Genus Distypsidera. 



DiSTYPSlDERA VOLITANS Macleay, var. obscura, var.nov. 



In my "Revision" (These Proceedings, 1906, p.334), I placed 



under B. gruti Pascoe, as •' yar.'?A", a species of Distypsidera 



from the neighbourhood of Cairns. Subsequently I received, 



from Mr. F. P. Dodd, more specimens of this form, taken by him 



in the open forest country inland from Cairns (Mareeba and 



Mount Garnet). An examination of the specimens sent by Mr. 



Dodd shows that this form is actually more nearly allied to D. 



volitans than to D. gruti. It must be considered probably to be 



a variety of D. volitans rather than a distinct species. I can 



differentiate it from D. volitans only by its wanting the whitish 



apical spots of the elytra. It may be differentiated from D. gruti 



by the pronotum less convex, more opaque, more closely and 



strongly transversely rugose, lateral borders more strongly 



developed; and by the elytral sculpture. In D. gruti the 



posthumeral white stripe becomes wider backwards, and bears 



few, if any, punctures; and the sculpture between this stripe 



and the suture is undulate-plicate; in D. volitans and var. 



obscura the posthumeral stripe, if present, does not become wider 



backwards, and its course is as coarsely punctate as the adjoining 



parts of the elytra, the space between this stripe and the suture 



being coarsely punctate, and hardly undulate-plicate. In D, 



gruti there is normally a juxta-scutellar white spot, but in I>. 



volitans and var. obscura the base is never maculate near the 



scutellum. The male of D. volitans and var. obscura differs from 



that of D. gruti by having the penis hooked at the apex. 



Length 12-14 mm.

In my " Revision," p. 328, I have said of the labrum : " In the 

 Diatypsidera-like form the setae are marginal, a seta being found 

 in every notch between the teeth." This is erroneous; in the 

 Cicindelce spurice of my " Revision " the labrum bears only four 

 tactile marginal setce — the first in the deep notch on each side of 

 the apex; the others, one on each side, in the hindmost lateral
