netc Species o/'IIisterida?. 189 



bistriato et margiue clevato ; clytris, striis 1-3 et subhuraorali 

 integris, 4 dimidiata, 5 subobsoleta, sulurali utrinque abbrcviata ; 

 propygidio pygidioque dense punctatis. 

 L. 4^-5 mill. 



Shortly oval, convex above, black, shining ; the head 

 wholly but irregularly punctured, stria coniijlete, carinifonn, 

 and straight anteriorly, with two somewhat feeble impressions 

 behind the stria ; the a])ex of the cpistoma is transverse and 

 the anterior edge is reHexed ; the thorax narrowest at the 

 anterior angles, then widening to the base, anterior angles 

 depressed and somewhat produced, the external lateral edge 

 is narrowly carinate and within it are two complete cariniform 

 strife; the interstice between the marginal rim and the outer 

 carinate stria is of the same breadth as that between the outer 

 and inner carinate stria, the interstices mentioned are irregu- 

 larly punctured ; the innermost lateral stria is continued 

 (somewhat finely and crenulate) behind the neck, the one 

 next the outer rim terminates behind the eye, the lateral 

 margins within the strife are broadly strigose-punctate, some- 

 what resembling the sculpture seen in //. longi'coUis, Mars., 

 but less strigose, the punctures spread out along the anterior 

 margin, but almost disappear behind the middle of the neck ; 

 the elytra, striaj 1-4 and inner subhumeral equally complete 

 and distinct and very obscurely crenulate, the internal sub- 

 humeral at its base turns towards the first dorsal stria, the 

 fourth stria is apical and scarcely reaches the middle (it is 

 broken and punctifbrm), the fifth is similar but more feeble, 

 the sulural is fine, shortened before the apex, and extends a 

 little only beyond the middle of the dorsum ; the propygidium 

 is somewhat closely and clearly punctured, punctures mostly 

 oval ; the pygidium punctures less oval and more dense. 



This peculiar species may be placed near B. longicollis^ 

 Mars.

This remarkable species is more circular in outline and flatter 

 than H. cosnosus, Er. ; the prosternum is without strife, irregu- 

 larly punctured with a microscopic strigose sculpture, and the 

 anterior lobe is clearly marginate ; the mesosternum is emar- 

 ginate and the marginal stria sinuous and complete. The 

 elytral subhumeral stria is complete.
