Proholosternus hrevistriuSy sp. n. 



Oralis, parum convexus, niger, nitidus; fronte minute pimctulata, 

 antice hand impressa, stria marginali integra ; pronoto iKvissime 

 et sparse punctulato ; elytris striis 1-4 iutegris, 4 basi hamata, 

 5 dorsali brevissima, suturali dimidiata ; propygidio fere laevi, 



L. 3| mil]. 



Oval, ratlier convex, black and shining ; the head, marginal 

 stria complete, not impressed ; the epistoma, surface very 

 minutely and sparsely punctulate ; the thorax, marginal stria 

 complete, surface sparsely and finely punctured, with an 

 antescutellar fovea ; the elytra, interstices of strise smooth, 

 striffi, outer humeral fine, inner humeral and 1-4 dorsal strong 

 and complete, 4 being markedly hamate at the base, 5 is very 

 sliort and dorsal, being just behind the middle of the disk ; 

 pygidia are almost smooth, but a few fine points are seen in 

 certain lights ; the prosternum narrow and bistriate ; the 

 mesosternum markedly raarginate ; the tibise are dilated. 



The short discal fifth stria distinguishes this species from 

 the other four at present known.

Ovatus, convexus, nigro-piceus, nitidus ; fronte conspicue rugoso 

 punctata ; pronoto stria marginali integra ; elytris striis tenuiter 

 impressis, margine late rufis ; prosterno striis antice conjuuctis ; 

 mesosterno parum acuto, marginato ; pedibus rufis. 



Oval, convex, piceous and shining; the head nigosely 

 punctured, especially on the anterior part, marginal stria 

 interrupted in the middle, apparently obliterated by the 

 rugosities ; the thorax, marginal stria complete, surface 

 ratlier closely punctured at the sides, less and more finely so 

 behind the head, and on the disk nearly smooth ; tlie elytra 

 someM'hat broadly red at the sides and along the apical 

 margin, the outer humeral is complete, inner very short and 

 basal, dorsal 1-4 complete, 5 very short and apical, sutural 

 complete and hamate at the base ; the propygidium is densely 

 punctured ; the pygidiura has a fine punctuation at the base 

 and is nearly smooth on the apex ; the prosternum, strias 

 widen out slightly at the base, are parallel along the sides, 

 and join, forming an arched outline anteriorly ; tlie meso-
