NOTES ON COLEOPTERA. 



By Frederick Blanchard. 



Dyschirius hispidus Lee. Besides the distinctions given in the 

 synoptic table in the Bulletin of the Brooklyn Ent. Soc, vol. II, p. 17, 

 this species is readily known by having only the normal number of seti- 

 gerous punctures on the thorax, namely, an anterior and a posterior one 

 on each side, while in se/ost/s and pilosus there are several intermediate 

 ones. 4 — 5 in setosus ; the other I have not seen. 



Stenus. Lieut. Casey has said, — Revision of Stenini, p. 5, — that 

 the tib:ae are unarmed in this genus, or group, as he prefers to consider 

 it. Two exceptions have come under my notice; 



In Stenus strangulatus Casey, the hind femora of the $ are 

 each armed with an acute tooth inside near the base. The femora are 

 also all stouter in the rj\ 



Again in Stenus erythropus Mels. , the $ hind tibiae have each 

 an obtuse tooth inside one-fourth from the apex. In this species the meso- 

 sternum of the ^ is furnished with a tuft of long yellow hair. 



Stenus juno Fabr. This species also has in the <$ a mesosternal 

 tuft of long hair as in erythropus, not observed by Lt. Casey, although 

 mentioned by Fauvel, "Faune Gallo-Rhenane," III, 246. There is also 

 a conspicuously longer and more dense pubescence on the basal half of 

 the posterior femora of the $ on the inner side not mentioned by either 

 author. 



Hister repletus Lee. This species, which appears in the Henshaw 

 List in the position originally given it by Maj. Leconte, should follow sub- 

 opacus, it belonging to the section Psiloscelis and conforming in habits 

 with the other species, being found in the nests of a small black ant. 



Prionus laticolhs Drury. The entire surface of the metasternum 

 and of the hind coxae in the $ is clothed with a long pubescence which 

 also extends more or less upon the mesosternum and its side pieces. In 

 the 9 however the hairs are so short and inconspicuous as to give the 

 under surface the appearance of being quite glabrous. In pocularis both 

 sexes are similarly clothed beneath with a long pubescence. Of the other 

 species of the genus I can only say now, owing to the absence of speci- 

 mens, that the Q of californicus and the ^ of itnericornis are pubescent 

 beneath, while the Q of palparis has the underside entirely glabrous. 



Prionus. — At my request Dr. Horn has kindly sent me the follow- 

 ing additional notes on the presence or absence of metasternal vestiture :
