Species of THater'idx. 421 



stria complete and straight anteriorly ; the thorax — inarginai 

 stria rather fine, incurved at the base, terminating in front 

 behind the eye, inner stria complete, rather strong, deflected 

 behind the eye, interstices between the stria3 somewhat wide ; 

 the elytra — humeral .stria3 tormed as in //. Jatilihius^ but fine, 

 dorsal 1-3 complete, J little shortened at the base, 5 apical, 

 terminating before the middle ; the ])ropygidium moderately 

 punctured, impressed on either side ; the ])ygidium evenly 

 and densely punctured on its upper surface, apex smooth ; 

 the prosternum — keel narrow before the coxte and without 

 sculpture ; the mesosternum emarginate, with a fine stria 

 laterally, stria obsolete in front ; the tibice are very broad, 

 anterior pair 3-dentate, the others spinose on the outer edge ; 

 tarsi very short. 



This species is larger than Hister latitibius^ Mars. ; the 

 chief differences are — the inner thoracic stria is not shortened 

 at the base, the sutural dorsal stria is absent, and the meso- 

 sternum has no clearly marked marginal stria. In one 

 example the frontal stria is sinuous anteriorly. Hister lati- 

 tibiiis is now considered to be a Contipus (Ann. Mus. Civ. 

 Genov. vol. xii. 1891, p. 23).

Homalopygus cavifrons^ sp. n. 



Oblongo-ovalis, rufo-briinneua, nitidus; antennis pedibusque con- 

 coloribus ; fronte excavata, punctata, utrinque striata ; clytris 

 striis l"-;j'" iutegris, suturali autice et postice abbreviata. 



L. 3 miU. 



Oblong-oval, reddish brown, shining ; the forehead sparsely 

 punctate, with a stria over the eye, excavated between the 

 antenna", excavation angulated posteriorly ; the thorax — mar- 

 ginal stria fine, invisible above at the sides, feebly crenulate 

 behind the neck, anterior angles rounded off, punctuation 

 rather large at and behind the anterior angle and continuing 

 less thickly to the hind angle, punctures evanescent on the 

 disk and before the scutellum ; the elytra — stride 1-3 complete 

 and crenulate at the edges, 4 apical and punctiform, scarcely 

 traceable, sutural fine, commencing at the middle and 

 shortened before the ajiex, there are a few -icattered punc- 

 tures on the apical portions of the elytral interstices and on 

 the interspace between the fourth ar i sutural strit« ; the pro- 

 iiyo-idium and pygidium are clearly, not thickly, punctured, the 

 ])unctuation of the latter is a little smaller ; the prosternum 

 is truncate at the base, striate, stria feebly crenulate, joining 

 at the base, diverging anteriorly, and terminating before the
