Hemicistela teStacea, n. sp. 



Elongate-oblong, whole surface and appendages testaceous 

 and glabrous; eyes black; suture of elytra, apical segments 

 of abdomen (sometimes), pronotum (rarely) fuscous. 



Head very finely punctate; eyes widely separated, moder- 

 ately prominent; antennae long, joints very narrowly tri- 

 angular, 3-10 subequal, 11 ■ shorter and finer than 10. 

 Prothorax depressed; truncate at apex and base, widest at 

 middle, thence arcuately narrowed to apex and obliquely 

 feebly narrowed to base; disc uniformly finely punctate; 

 medial line lightly impressed or wanting; two small trans- 

 verse foveae at base. Scutellum small, semi-circular. Elytra 

 wider than prothorax at base and four times as long, parallel, 

 or lightly enlarged behind middle; finely but clearly striate- 

 punctate, punctures in striae round, fine but distinct through- 

 out; intervals quite flat and minutely but clearly punctured. 

 Underside smooth and nitid. Legs simple, hind tarsi with 

 basal joint as long as the next two. Divi. — 5-6 x lf-2-| mm. 



Hah. — Western Australia: Swan River (A. M. Lea). 



Fourteen examples show a fragile insect without strongly 

 defined characters. The prothorax is shaped as in //. 

 discoidalis, Blackb., and indeed the two species are very 

 similar in structure. The mandibles are clearly simple at 

 apex. H. testacea differs from discoidalis in colour paler, 

 without the lateral obfuscation of elytra, antennal joints more 

 elongate, elytral intervals quite differently punctured (closely 

 and finely in testacea, sparsely "subfortiter" in discoidalis). 

 Types in the South Australian Museum. 



As the following two species have never been identified 

 in any Australian collection, and were quite inadequately 

 described in three lines (each) of Latin — in one instance 

 without any dimensions — I append fuller descriptions : — 



DiMORPHOCHTLUs (Allecula) gouldii, Hope. 



Elongate, ovate, red or black, glabrous; antennae, tibiae, 

 and tarsi red. 



Head produced strongly in front, labrum very prominent; 

 mandibles simple (one-pointed) ; sparsely and finely punctate; 

 eyes large and prominent, separated (in both sexes) by a 

 space of about half the diameter of one ; antennae linear, very 

 slender, joint 3 slightly larger than 4, 4-6 equal, 7-10 shorter 

 and wider than preceding, 11 much narrower than 10. Pro- 

 thorax (about 2x3 mm.) truncate at apex and base, hind 

 angles rectangular, sides parallel behind, arcuately narrowed 

 on front half, anterior angles obsolete ; disc sparsely, lightly 

 punctate, with small transverse bp>sal foveae, and without
