Entisberus interruptus Scudder , sp.n.

(Fig. 4)

Female. Description. COLOURATION. Head dark blackish-brown; antennae ochraceous with basal three-fourths of first segment dark brown, and fourth segment medially brown; rostrum ochraceous with first segment vaguely brown basally. Pronotum with anterior lobe dark brown; posterior lobe ferrugino-ochraceous with ferruginous punctures, and with lateral areas and vague central and medio-lateral longitudinal brown streaks. Scutellum dark ferruginous-brown, with stem and arms of Y-shaped elevation ochraceous. Hemelytra ferrugino-ochraceous with ferruginous punctures; costal margin of corium with distal part near apex brown, and with a brown streak in apical half; area around pale spot at inner angle of corium also brown; membrane with distinct brownish area laterally and posteriorly. Legs ochraceous with basal third of fore femora, and basal four-fifths of middle and hind femora dark ferruginous; coxae and trochanters dark ferruginous. Venter dark ferruginous-brown. STRUCTURE. Dorsal surface dull with membrane somewhat shiny. Head with short, decumbent, golden setae, shorter than those on anterior lobe of pronotum; vertex moderately convex; eyes rather prominent with half of width projecting beyond anterolateral angles of pronotum; ocelli small and inconspicuous; antennae with prominent, rather erect setae, most of which almost twice length of thickness of second and third antennal segments, projecting beyond apex of head; venter of head with posterior end of bucculae prominent and ending at level of antennal insertion; antennal tubercles prominent from above; rostrum just surpassing fore coxae. Pronotum with punctures on anterior lobe smaller and more dense than those on posterior lobe; anterior lobe of disc with vague, oblique, impunctate lines, but lobe with dense, decumbent, golden pubescence, and not obviously pruinose; posterior lobe of disc without obvious setae, and with postero-lateral angles not prominently angled. Scutellum with Y-shaped elevation highest in middle, and with middle of ‘Y’ interrupted by dense punctures, making center rather ferruginous. Hemelytra macropterous and extending beyond end of abdomen; costal margin of corium distinctly sinuate, but at most with very small serrations basally; apical margin of corium gently sinuate, and distinctly concave near inner angle. Mesosternum without prominent spines. Abdominal venter with lateral parts of sterna bare, but with short, erect setae in median area; rugulose sutures prominent. MEASUREMENTS (n=3). Head width 0.63 (0.60–0.67); head length 0.49 (0.48–0.50); vertex width 0.36 (0.35–0.37); antennal measurements 0.35 (0.33–0.37): 0.42 (0.40–0.43): 0.31 (0.30–0.32); 0.39 (0.38–0.40); rostral measurements 0.25 (0.23–0.27): 0.22: 0.16 (0.15–0.17): 0.24 (0.20– 0.27). Pronotal width 1.28 (1.23–1.33); pronotal length 0.78 (0.77–0.78): scutellar width 0.78 (0.75–0.83); scutellar length 0.63 (0.60–0.65). Total body length 3.17 (3.08–3.25).

Holotype: Female, [Philippine Is.], Mindanao, Davao Province, Meran , Mt. Apo , E. slope, 6000 ft., beaten from tree ferns, original forest, 9.xi.1946 (H. Hoogstraal & D. Heyneman leg.) ( CNHM Philippine Zool. Exped. 1946-47) [ CASM] .

Paratypes: 2 ♀, data as type [CASM, Scudder Coll.].

Discussion. Similar to E. archetypus in general appearance, but distinguished from this species and E. bergrothi in the colour of the legs, the first antennal segment, and in the structure of the pronotum.

Etymology. The specific epithet is the Latin adjective interruptus from interrumpo (meaning break in the middle) referring to the pale Y-shaped elevation on the scutellum being interrupted by dense punctures, making the centre rather ferruginous.
