190 On new Species of Ilisteridie. 



Fairm., as the type, and JY. 5-striatus, nodlcornis^ dux, and 

 imitans, Lew. Some of the generic characters correspond to 

 those in Notolister, especially in the form of the sterna, but 

 the antennal fossettes are in the anterior thoracic angles, not 

 just behind them ; the antennae have a nodule on the scape j 

 the body is more convex and sometimes gibbous ; there is no 

 transverse frontal stria and the thoracic lateral sulcus, so 

 conspicuous in Notoliater, is wanting ; the raesosternum is 

 sometimes sinuous and sometimes not ; the anterior tibia? are 

 multidentate. 



Pachycrcerus lat'iceps, sp. n. 



Subcylindricus, niger, nitidus, pedibus piceis ; capita lato, fronte 

 punctata, stria Integra, clypeo impresso ; thorace stria marginali 

 antice interrupta ; elytris striis 1-3 integris, 5 dimidiata, 4 et 

 suturaU ante basi abbreviatis ; prosterno bistriato, striis rectis; 

 mesosterno margiuato ; tibiis anticis o-deutatis. 



L. 4-4^ mill. 



Somewhat cylindrical, black and shining ; the head is hirge 

 and clearly but not densely punctate, frontal stria complete ; 

 the thorax is rather irregularly punctured, the punctures on 

 the scutellar region being very fine and few, marginal stria is 

 interrupted behind the middle of the head ; the elytra, strise, 

 outer humeral apical and dimidiate, inner wanting, 1-3 dorsal 

 complete, 4 and sutural are shortened before the base, 5 

 dimidiate or a little longer, the interstice between the second 

 and third striiB widens out at the base; the propygidiura and 

 pygidium are clearly but not densely punctate ; the pro- 

 sternum, anterior lobe coarsely punctured, keel rather wide 

 and bistriate, striae are feebly carinate and parallel to each 

 other in front of the coxee ; the raesosternum, its projection is 

 somewhat robust and prominent and the marginal stria 

 complete. 



The form and colour of the species resemble those of 

 P.facetus, Mars., but its head is much more robust and more 

 coarsely punctured, the fourth dorsal stria is not complete, 

 and the prosternal keel is much wider and the marginal striaj 

 are parallel, not joined anteriorly, and the raesosternal jiro- 

 jection is more robust and prominent.

Pelorurus ruptistrius, sp. n. 



Breviter oralis, nigro-cuprcus, nitidus ; elytris viridi-cxruleis, fronte 

 tenuiter impressa vix dense punctulata ; prouoto stria inlt'gra,
