Piti, July 18, from pumpkin leaves having mildew, 28 examples, Swezey; Piti, June to November, 14 examples, Swezey; Yona, April 27, 29, among dead leaves, three examples, Bryan; Inarajan, July 25, Sept. 30, on rice, four examples, Swezey; Machanao, Aug. 11, on sugar cane, two examples, Swezey; Fonte Valley, Aug. 7, from weeds, five examples, Swezey; Fadian, Aug. 19, on Sida, two examples, Swezey .

First described from Linga, Sunda Islands, the species is widely distributed, being known from Ceylon ( F. quisquiliarius Nietner), Japan ( F. cribriceps Marseul) and the Chusan Archipelago (coll. J. J. Walker in British Museum). For synonymy see Krekich von Strassoldo (Wien. ent. Zeitung 32: 231, 1913).

A striking character in the female of this species that does not appear to be mentioned in any of the descriptions, is the high pointed crest on the pygidium. This is perhaps less developed in cribriceps than in quisquiliarius and the present form.
