Coleopteva, Part I. 119 



side of apex of elytra and of each of the abdominal segments ; 

 the two apical sefrments, however, with numerous hairs. 



Antennae comparatively short. ^ Prothorax large, strongly 

 convex, moderately transverse, closely enveloping the bead, 

 posterior angles rounded hut pnxluced and enveloping the 

 elytra ; indistinctly punctate. Elytra narrower than prothorax 

 at base and much narrower at apex, posterior angles strongly 

 rounded, shorter along suture than towards sides, rapidly di- 

 minishing in vertical height from base to apex, sides just 

 perceptibly projecting outwards and downwnrds; densely and 

 finely punctate. Length 3, to apex of elytra IJ mm. 



Hah. — W. Australia : Bridgetown. 



A very distinct species, appearing top-heavy from the un- 

 usually large and convex prothorax and peculiar elytra : the 

 punctures and pubescence of the latter are very sparse in the 

 vicinity of the scutellum. Numerous specimens were seen in the 

 nest of a species of " sugar " ant under a stone. 



Conosonia ;n\r>necophihiui, n. sp. 



cT. Moderately shining. Dull reddish-testaceous, appendages 

 paler : base of prothorax, apex of elytra and middle of abdomen 

 slightly infuscate. Densely clothed with short and somewhat 

 golden jDubeseence, longer on abdomen than elsewhere ; front of 

 head, sides of prothorax, elytra and abdomen with long brownish 

 or blackish hairs, denser on abdomen than elsewhere. 



Antennae rather stout, fifth to tenth joints transverse. 

 eleventh almost as long as three preceding combined. Prothorax 

 decidedly transverse, base gently emarginate throughout ; indis- 

 tinctly punctate. Elytra comparatively large, outline con- 

 tinuous with that of prothorax, and not much wider at base 

 than at apex, slightly longer than prothorax ; apex truncate, 

 the posterior angles very slightly rounded ; sides slightly flat- 

 tened out but not upturned ; with dense subasperate punctures. 

 Subapical segment of abdomen deeply triangularly excised. 

 Length 3, to apex of elytra \\ mm.

1 Although I have now foui- specmiens, I have not been able to place the antennae of 

 any of them in a satisfactoiT position for close exaniination.
