228 Mr. Arthur M. Lea's Revision of the 



and apical half of antennae black ; intermediate joints of the latter 

 and apical joints of tarsi more or less infuscate. 



Head without excavations ; slightly flattened and with very- 

 distinct punctures between eyes. Antennae thin, almost extending 

 to hind coxae. Prothorax elongate, strongly impressed at base. 

 Elytra almost impunctate. Basal of joint tarsi moderately long, 

 slightly rounded and with a black inner rim. 



Length to apex of elytra If, of abdomen 3 mm.

The simple head of the male (in shape much as that of 

 ohliquice])s) readily distinguishes it from most species of the 

 genus ; the elytra are coloured much as in some of the 

 varieties of varius. The colours much resemble those of 

 the preceding species except that a greater space in each 

 shoulder is pale, but in that species the head is largely 

 excavated. 



A specimen (evidently the female) differs from the two 

 males before me in having the head smaller, more convex 

 and with smaller and sparser punctures ; its elytra also 

 have their basal marking larjijer and continuous across the 

 suture. 



Helcogaster bilobus, n. sp. 



^ . Black ; apical half of upper and the entire lower surface of 

 head, prothorax, shoulders and a short space behind them, knees 

 (largely), base of tarsi, and basal joints of antennae, flavous or 

 reddish-flavous. 



Head distinctly and almost regularly punctate, base transversely 

 strigose, concave but not largely excavated between eyes and without 

 frontal tubercle. Antennae long and thin, almost extending to 

 hind coxae. Prothorax moderately elongate, strongly impressed at 

 base. Elytra with sparse and very indistinct punctures. Basal 

 joint of front tarsi comparatively small but with a black inner rim. 



Length to apex of elytra 2h, of abdomen 4 mm. 



$ . Differs in being larger, the head more convex, with a scarcely 

 traceable median impression the eyes smaller, more to the front and 

 the front tarsi simple.
