neiv Species of Histerldse. 2')'i 



stria complete and the interstice between it and the lateral 

 stria is rather broad, only narrowing at the base ; the elytra, 

 striai 1-4 complete, 1-3 strong and rather wide, 4 liner, 5 and 

 sutural apical, short and broken, humeral striee absent ; the 

 propygidium is coarsely and thickly punctate, with a rather 

 wide impression on either side; the pygidium is also coarsely 

 punctate, with a gibbosity on either side near the base (re- 

 sembling H. coronatus, Mars., in this character) ; the pro- 

 sternum, anterior lobe with scattered shallow punctures, 

 keel bistriate, striai joining before and behind, are ratlier 

 fine and before the coxaj sinuous ; the mesosternum is sligiitly 

 sinuous behind the keel of the prosternum, marginal stria 

 rather fine and crenulate ; the metasternum has a similar 

 stria which follows the sutural line and widens out laterally 

 beliind ; anterior tibise 4-dentate, apical tooth bifid. 



This species must be placed in the American series close 

 to H. nodatus and buUatus, Lew., and near to II. coronatus^ 

 Mars., which it resembles in the form of its pygidium.

L. 4i mill. 



Rather shortly oval, convex, black and shining; the head 

 very finely, not densely punctulate, stria rather strong, arched 

 anteriorly, angulate above the eyes, and joining a transverse 

 stria before the neck ; the thorax, marginal stria very fine, 

 visible above at the anterior angles, outer lateral stria ceases 

 behind the eye and continues halfway down the lateral edge, 

 inner is complete and slightly crenulate, especially behind the 

 anterior angles, the basal edge is punctate, but the points do 

 not reach the scutellar region ; the elytra, dorsal strise, 1-4 

 complete, 5 apical and very short, sutural much shortened in 

 front and a little shortened behind; the propygidium and 

 pygidium are densely and coarsely punctate, the former is 

 impressed on either side behind, the latter is slightly bi- 

 lobed ; the prosternum, anterior lobe margined with a fine 

 stria and has large shallow conspicuous punctures, keel 

 bistriate, striee clearly joined before and behind and are widely 

 sinuous in the middle ; the mesosternum is feebly sinuous in
