Adult habitus. Unknown, notes lost.

Male. Unknown.

Female. Unknown, notes lost.

Larva. Unknown.

Egg. Spindle shaped with low, button-like collar ( Fig. 28 ). Total length ca. 446 μm, equatorial width ca. 360 μm. Much of chorion beyond shoulder covered with faint hexagonal follicle cell impressions bearing obscure pits in floors of follicle cell impressions ( Fig.30 ); area surrounding collar without follicle cell impressions ( Fig. 31 ). Micropylar row subequatorial, orifices almost linear, canals vertical ( Fig. 31 ).

Comments. One of us (IS) examined a single female in the collection of the Institute of Zoology, Academia Sinica, Beijing and obtained the egg sample. Unfortunately notes and sketches made for this specimen were lost during travel. The egg of this species differs from those of C. drukpa , C. semibrachyptera and C. sabulosa (described above). Additional material is needed in order to determine the identity of this species.
