slightly obscui'ed by pubescence. The extreme base of the head is 

 transversely strigose, but this portion is usually concealed. 



9 . Head less transverse and with smaller eyes, not excavated and 

 with distinct piinctures, basal third regularly convex, apical two- 

 thirds flattened, with a feeble median longitudinal elevation in 

 front. 



It will be well for future entomologists before describing 

 new species of the genus to try to identify this species; 

 the sculpture of the head of the male is very distinct but 

 the colours are very variable and eachof its colour varieties 

 is exactly or almost exactl}^ represented in other species. It 

 is widely distributed in New South Wales, and fully half 

 of the specimens of the genus taken by myself or sent to 

 me for examination belonged to it. The cljaracteristic 

 appearance of the male head is best seen from behind, the 

 five tubercles being quite conspicuous and apparently 

 (though really not so) in an even line. The head of the 

 female, however, is much as in many other species.

Helcogaster carinaticeps, Lea (Carphurus), I. c, p. 248. 



I was deceived by the sculpture of the head of the type 

 of this species and noted it as a male Carphurus ; its front 

 tarsi are simple, however, and it is really a female 

 Helcogaster. I do not know its male, but the tricarinate 

 should render the female easy of recognition.
