this specimen as it is said to do from bicolor, and I believe the 

 differences to be sexual, the Benalla specimen is certainly a 

 female (its ovipositor is protruding and its elytra do not 

 entirely cover the abdomen, but this latter may be character- 

 istic of the gravid female only), the other is certainly a male 

 (its front tarsi are noticeably dilated). Blackburn noted the 

 type as having "traces of a central longitudinal keel, and 

 some discal furrows" on the pronotum, which he thought 

 were possibly abnormal. On neither of the specimens before 

 me is there trace of a central keel, but on the specimen from 

 his own collection there is a large shallow subfoveate depres- 

 sion on each side of the middle towards the base ; on the 

 Benalla specimen these are much less in evidence. 



Trichosalpingus obscurus, Blackb. 

 A specimen from Galston possibly belongs to this species; 

 it is the size of the type (1|- lines) and differs from brunneus 

 as the type is said to do, but its appendages are entirely pale, 

 whereas on the type apparently only the tarsi are paler than 

 the other parts. 



Trichosalpingus variabilis, n. sp. 



Of a dingy reddish- or piceous-brown, with paler mark- 

 ings. Closely covered with short, ashen pubescence. 



Head rather more convex than usual. Eyes large, lateral, 

 and prominent. Antennae rather thin, but apical joints 

 slightly dilated, scarcely passing base of prothorax. Prothorax 

 slightly wider than long, sides gently rounded and widest near 

 apex, with a rather deep oblique impression on each side of 

 base. Elytra much wider than prothorax, sides gently 

 dilated to apical fourth and then widely rounded, with vague 

 traces of striation. Length, 3-3^ mm.

There is a single specimen from each locality before me 

 and no two are exactly alike ; quite possibly some other 

 specimens that have been put aside unnamed should also have 

 been referred to the species ; they mostly have the appendages 

 more or less distinctly paler than the body-parts, but the 

 sides of the elytra are also usually paler than the adjacent 

 parts. The type (from the Dividing Range) has two pale 

 spots on each elytron : a large one commencing on the shoulder 

 and terminating near the suture at the basal third, and a 

 small subsutural one beyond the middle, the space between 

 the spots appearing as an obscure fascia. The specimen from
