108 [June, 



in Canada (Kirby). The general direction of the markings of the elytra is 

 transverse, sometimes they are so numerous that the elytra appear dull cinereous, 

 with a few transverse black lines. 



5. D. murinus, oblongus niger, pubescens, capite thoraceque cinereo-ful- 

 voque variegatis, elytris cinereo-variegatis, scutello densius pubescente, infra 

 albidus, abdomine lateribus segmentoque ultimo nigris, hoc basi albo-bipunc- 

 tato, antennis nigris. Long. *3. 



Linn. Faun. Suec. (synon. vid. Erichson, Ins. Deutschl. 429). 



Middle and Southern States and Nebraska ; probably imported. This species 

 differs from the last by the color of the antennae : the markings of the elytra are 

 less disposed to become confluent. 



6. D. s o b r in u s, oblongus, niger, subaequaliter fusco-pubescens, (sparsius 

 in elytris) ; subtus albidus, abdomine maculis nigris quadruplici serie ornato, 

 femoribus albo-annulatis, antennis obscure ferrugineis. Lonjj. -32. 



One specimen, Texas, Mr. Haldeman. This has entirely the form of D. 

 nubilus, but the uniform pubescence, and the four abdominal series of spots will 

 enable it to be readily recognized : the last joint of the abdomen is white, with 

 two lateral and two fainter internal black spots at the base, corresponding to 

 the spots on the other segments. 



7. D. talpinus, oblongus, niger, pubescens, capite thoraceque cinereo va- 

 riegatis, pilis fulvis intermixtis, scutello fulvo pubescente, elytris lineolis 

 angustis transversis cinereis variegatis; subtus albidus, abdominis lateribus seg- 

 mentoque ultimo nigris, hoc basi albo bimaculato, antennis piceis apice dilutiori- 

 bus, femoribus albo annulatis. Long. *24 '32. 



Mannerheim, Bull. Mosc. 1853, 257. 



California and Oregon ; abundant. The lines of the elytra are very narrow, 

 and occasionally are varied with fulvous hairs : the color appears from the nar- 

 rowness of the markings much darker than in our Eastern species. 



8. D. r a 1 1 u s, oblongus magis elongatus, griseo-pubescens, (maculis denudatis 

 variegatis) thorace minus subtiliter punctato, subtus albidus, abdomine griseo 

 nebuloso, antennis nigris. Long. '20'. 



One specimen, California, Mr. Child. This species is a little narrower than 

 the preceding, and from the appearance of the hair of the upper surface looks as 

 if well preserved specimens would be uniformly pubescent, as in the densely 

 pubescent varieties of D. murinus. The specimen being a female, I am not 

 certain that it belongs to this division, but have placed it near those to which it 

 seems most closely allied. The hairs of the thorax appear slightly intermixed 

 with fulvous, and the punctures are more distinct than usual. The pectus is 

 white as usual, but the abdomen is of a dirty clouded white color, becoming 

 white only at the middle of the base. 



9. D. m u c o r e u s, oblongus, magis elongatus, nigro-piceus, pubescens, tho- 

 race lateribus et apice, elytrisque versus basin densius pubescentibus, subtus 

 candidus, segmentis abdominis gutta utrinque nigra notatis, (pedibus anten- 

 nisque piceo-rufis). Long. -23. 



One mile from New York. This specimen is evidently immature, but the 

 white undersurface, marked only with the black lateral spots will enable it to 

 be recognized : the last segment of the abdomen is white, having only the lateral 

 spot each side at the base. The femora are not annulated. The appearance is 

 that of a small D. vulpinus, but the sexual characters are those of the present 

 group. 



10. D. p u 1 c h e r, oblongus, rufus, subtilius cinereo pubescens, elytris nigris 

 hurneris oblique runs. Long. *25. 



Philadelphia, Mr. Newman, in a dead oak tree. A moderately robust species, 

 uniformly but not densely pubescent, both above and beneath, and very re- 

 markable by its color. The elytra in some lights show some very faint traces 

 of striaj behind the middle. Five specimens were found.
