Pac^iycrcBrifi spatt'osun, sp. n. 



Ovalis, parum depressus, nij3:er, nitidiis ; tlytris obscure iciieo-nif»ri3 ; 



capite imprcsso, stria integra ; pronoto stria marginali late inter- 



rupta. 

 L. 4 mill. 



Oval, ratlicr depressed, black, shining, with the elytra 

 feebly reneoiis ; tlie head is rather narrower than in P. cjjan- 

 escenSy Er., but the form of the stria and the frontal impres- 

 sion are similar allowing for the widtii, the punctuation is 

 slightly closer ; the thorax is also like Ericlison's species in 

 punctuation and in the lateral stria ceasing behind the eye ; 

 the elytra, stria3 1-3 complete, 4-5 coequal, apical and about 

 ^ of elytral length, sutural very short, terminating anteriorly 

 in a line with the fourth and fifth, subhumeral external 

 dimidiate ; tlie propygidium and pygidium are punctured 

 somewhat simiharly to P. ci/anescens, but the punctures are of 

 a slightly smaller grade and the segments are flatter ; the 

 prosternum is wide and the strias are parallel to each other 

 and terminate at the suture behind the anterior lobe; the 

 keel is as wide again as that in P. cj/anescens, and with the 

 lobe is punctulate ; the raesosternum, marginal stria complete, 

 but very fine at the space behind the keel ; the anterior tibiaB 

 are somewhat slender and have three or four small teeth. 



The species in some of its characters is intermediate 

 between P. cyanescens and P. latus, Lew.

Pachycrcerus cariniceps^ sp. n. 



Oblongo-ovatus, parum convexus, obscure rufo-brunneus ; capite 

 punctulate, stria carinata ; pronoto utrinque sinuato, stria lateral! 

 carinata, angulis anticis subfoveolatis ; elytris, striis 1-4 et 

 suturali completis, 5 apicali. 



L. 2| mill. 



Oblong-oval, rather convex above, obscure reddish brown, 

 shining ; the head obscurely and sparsely punctulate, frontal 

 stria complete and cariniform, the carina is the least strong on 

 the middle of the anterior edge, the clypeus is transversely 

 concave at the base, with a strong ridge dividing the concave 

 part from the anterior portion ; the thorax subfoveolate at the 

 anterior angle, distinctly sinuous laterally before the base, 

 the lateral stria cariniform, carina strongest at the sinuosity, 

 stria complete but fine and crenulate behind the head, surface 

 somewhat sparsely and finely punctulate ; the elytra — strise,
