BYRRHID^E 33 



moderately separated, with the interspaces where visible polished 

 and without minute sculpture, the elytra with fine striae, the broad 

 flat intervals smooth, polished and almost punctureless, the entire 

 upper surface very densely clothed with short, coarse, subsquami- 

 form hairs, with conspicuous blackish bristles interspersed, the 

 vestiture generally blackish, with condensed black vittae on the 

 alternate intervals of the elytra, the latter also with a transversely 

 lunate area inclosed by pale bands nearly as in the preceding; pro- 

 thorax rather short; elytra notably long, three and one-half times 

 as long as the prothorax, evenly elliptic in outline; under surface, 

 with coarse, close sculpture, the metasternum with the coarse trans- 

 verse punctures coalescent anteriorly but isolated posteriorly, the 

 rather slender erect stiff hairs of the abdomen attached each at the 

 posterior margin of a flat tubercle, the latter large and strong through- 

 out on the last segment, giving an eroded appearance, the tubercles 

 moderately separated, the interspaces granulato-reticulate. Length 

 3.7-3.8 mm.; width 2.25-2.3 mm. Manitoba (Aweme), Norman 

 Criddle hystrix n. sp. 



In the European murinus, as represented by a German specimen 

 at hand, the abdominal sculpture is stronger and denser throughout 

 and the hairs of the under surface are shorter, more decumbent and 

 more squamiform than in either of the above species; the bristles 

 of the upper surface are less numerous and scarcely more than 

 half as long. The dimensions of this European example are 3.7 X2. 3 

 mm., which coincide very nearly with the proportional dimensions 

 (2^X1^ 1.) given by Melsheimer (Pr. Acad. Phila., 1844, p. 117) 

 for his Byrrhus undatus, of which glabellus Mels. (1. c., p. 118) is a 

 synonym both described as Pennsylvanian. If undatus Mels., 

 is really the same as murinus Fabr., the latter will have to be 

 listed in our catalogues, but not having seen a specimen I am 

 unable to decide; undatus and glabellus may possibly have been 

 founded upon accidental importations, which failed to establish 

 the species here, though the genus Porcinolus is not only endemic, 

 as indicated by the two quite different species above described, 

 but is probably much more developed here than in Europe. Pos- 

 sibly hystrix may be the same as undatus Mels., but of this I have 

 no means of judging. 



Curimopsis Gangl. 



The species of this genus inhabiting North America are recorded 

 in our lists under the name Syncalypta, and, though placed as a 

 subgenus of the latter in the European catalogue, I think the 

 differences are sufficiently pronounced to compel its recognition
