310 AUSTRALIAN' COLEOPTERA : NOTES AKD XEW SPECIES, 



terior angles definite and obtuse; disc covered with large confluent punctures, the 

 short bristles more obvious on margins, lateral foliation not differentiated in 

 sculpture from disc. 



Scutellum triangular. 



Elytra considerably wider than prothorax at base ; punctate-striate, the striae 

 shallow, the seriate punctures large and seiiarated by transverse ridges; all inter- 

 vals gianulose and bristled, the alternate four intervals rather strongly convex, 

 forming — especially on basal area — rounded costae; underside coarsely and closely 

 punctate; tibiae not enlarged at apex. Dimensions: 7-8 x 4 (vix) mm. 



iJab.— Stanthorpe, Queensland (Von Wieldt). 



Three examples from the Queensland Museum show a species clearly distinct 

 from all described species, except G. custipenne Cart., in its sub-costate intervals, 

 but costipenne has a gi-anulose pronotuni, with other marked differences of sculp- 

 ture and clothing. Types in the Queensland Museum. 



HyOCIS INIJUILINA, n. sp. 



Short and rather wide; head, prothorax and appendages pale red, elytra 

 and underside brown, or reddish, whole surface opa(iue. 



Head and prothorax rough, not perceptibly punctured; joints of antennae 

 very closely adjusted, the apical four tumid. 



Prothorax convex, widest near front, sides gradually narrowed behind, scarce- 

 ly or very feebly sinuate behind, with clearly foliate margins; extreme edge very 

 minutely serrate, front angles rounded, hind angles obtuse. 



Elytra wider than prothorax at base, convex, slightly widened behind middle, 

 seriate-punctate; each with about 9 rows of large, rather shallow punctures, in- 

 tervals flat (or nearly so). Dimemions: U mm. (vix) long. 



llal)_ — Swan River, Western Au.stralia, in nests of the ant Tridomyrmex 

 conifera (J. Clark). 



I am indebted to that indefatigable collecter, Mr. Clark, for two specimens 

 of this interesting species. The smallest of the genus, it is easily distinguished 

 by its almost flat elytral intervals, and short, wide form. IJoth //. nigra Blackb. 

 and //. minor Cart, look comparatively large. Type in Coll. Carter. 



Elascus major, n. sp. 



Elongate, parallel, bi-o\vnish-bla<-k, surface in parts thinly clad with sliort 

 recumbent bristles. 



Read sub-depressed in front, tubereulate near base, antennal orbits widely 

 arched al)ove frontal surface; eyes round, sub-conically protuberant; antennae 

 very wide and strongly bristled except towards apex. 1st and 3rd joints longer 

 than rest (3rd twice" as long as 4th) 4th-8th successively a little narrowed, 9th 

 and 10th slightly wider than 8th, 11th truncate, shorter and narrower than 10th. 



Prothorax uneven in surface, strongly produceil in middle l)oth in front and 

 at base; anterior angles rectangular, posterior sligiitly wider but clearly defined; 

 sides nearly straiglit, a little widening behind, witii a rather wide horizontal 

 margin— thence rising steeply to the two irregular ridges extending from base 

 to apex and terminating in round tubercles on anterior margin, a wide central 

 depression, surface shagreened with some fine tubercles on margins. 



Elytra considerably wider than prothorax at base, shoulders sciuarely rounded, 

 sides without horizontal border; each elytron with three flexuous costae, ter-
