Head rather large, with a deep transverse interocular 

 excavation; densely punctate and opaque. Antennae com- 

 paratively long. Prothorax about as long as the greatest 

 width (near apex), base much narrower than apex, near base 

 with a wide and rather deep, closed depression. Elytra 

 moderately long; with minute, rugulose punctures. Basal 

 joint of front tarsi rather large, lopsided, and with a black 

 inner comb. Length, 2 mm.

In general appearance close to the preceding species, but 

 the head deeply transversely excavated; it is evidently close 

 in appearance also to H. nigriceps, but differs from the 

 description in being smaller, head with excavation bisinuate, 

 instead of trisinuate, posteriorly (the sinuations although 

 wide are feeble, and the space dividing them is very obtuse), 

 antennae longer, four of the basal joints partly or entirely 

 pale, and the knees pale. In my table it would be placed 

 with H. insularis, which is a much larger species, with the 

 excavation different, the part dividing the sinuations acute, 

 antennae wider, and knees no paler than the adjacent parts. 

 The head of the Mittagong specimen, when viewed from 

 behind, appears to have a minute tubercle on granule close 

 to each antenna, but on the type these are not evident. 



Helcogaster pignerator, n. sp. 



<5 . Black ; front of head and a large spot near each 

 eye, prothorax, and part of antennae flavous. With sparse, 

 dark hairs, more numerous on sides of abdomen than else- 

 where. 



Head rather large, with a wide, sinuous, interocular ex- 

 cavation, its posterior end trisinuate; inter- anten nary space 

 irregularly elevated ; in parts with dense punctures. Antennae 

 moderately long. Prothorax slightly longer than greatest 

 width (near apex), a wide but rather shallow and open 

 depression near base. Elytra rather long ; minutely rugulose- 

 punctate. Basal joint of front tarsi lopsided, with a black 

 inner comb. Length, 5 mm.

 Type (unique), I. 11907. 



The three conspicuous spots give the head a curious 

 appearance, the front one at first appears to be confined to 

 the inter-antennary space, but is continued along the sides 

 to near the eyes, and passes completely across the under- 

 surface; the other spots are smaller, round, and sharply 

 defined. In some lights the elytra have a faint bluish gloss, 

 and their extreme lateral margins from the base almost to
