HOMOTRYSIS KERSHAWI, n. Sp. 



Elongate, subnavicular ; chocolate-brown, head and pro- 

 notum subopaque, elytra and underside nitid; labrum, palpi, 

 basal joints of antennae, and tarsi reddish. 



Head and p^othorax densely (confluently) punctate; the 

 eyes very large and prominent, separated by a distance of 

 about half the diameter of one eye; antennae long and very 

 slender, the joints linear, 3 longer than 4, 5-11 successively 

 shorter. Prothorax very convex, about as wide as long, 

 slightly narrowed anteriorly; apex a little sinuate, front 

 angles obtuse, but sharply defined, base truncate, hind angles 

 rectangular, sides nearly straight, on basal half gradually 

 contracting in front; basal foveae scarcely defined, disc with- 

 out medial line, thinly margined at base and sides, the lateral 

 margin not seen from above. Elytra considerably wider than 

 prothorax at base and about three and a half times as long; 

 striate-punctate, the striae wide, seriate punctures less obvious 

 near suture, but large, square, and divided by canoellate 

 ridges on external half; intervals convex, coarsely punctate, 

 with a line of thin pale recumbent hair on each. Sternum 

 coarsely, abdomen more finely punctate, each puncture on the 

 latter bearing a short recumbent red hair. Dim. — 10-11 x 

 3J-4 mm. 



Rah. — Overland Railway, 24 miles west of Kycherny 

 Soak, collected by Mr. Cliandler. Western Australia: Eucla. 



Four male examples show a species specifically like a 

 common Western Australian insect that I have doubtfully 

 identified as H. obscura, Borch., but differing in smaller size, 

 more prominent and closely-set eyes, antennae quite different, 

 elytra pilose, etc. It is evidently not H. scabrosa, Champ., 

 whose antennae are ''rather stout," joint 3 "shorter than 4," 

 etc. Type in the National Museum, Melbourne. 



HOMOTRYSIS PALLIPES, U. Sp. 



Elongate, subparallel, subopaque-black ; labrum, palpi, 

 legs, and tarsi testaceous, knees infuscate. Elytra with short, 

 sparse, reddish hairs, underside with longer recumbent hair. 



Head densely punctate ; eyes of male separated by a space 

 of half the diameter of an eye, in female more widely separ- 

 ated, antennal joints rather stoutly linear, 3-11 subequal in 

 length, 3-5 slightly widening apically. Frnfhorax truncate at 

 apex, slightly sinuate at base, sides nearly straight on basal 

 half, arcuately narrowed to apex; front angles obsolete, 

 posterior sharply rectangular; surface very densely punctate, 

 the punctures subcontiguous, a shallow basal impression near 

 angles, and a few short reddish hairs near sides. Scutellum
