One specimen found at Fort Laramie. 



mrocHRous. 



HI. s(|iiniilO*iiK, longiusculus, piceo-oeneus, dense griseo-squamosns, breviter pubescens, capite 

 tboraceque confertissime punctatis, hoc subrotundato, lateribus baud dentatis, elytris thorace non 

 latioribus, punctis subquadratis striatim positis, postice obsoletis ; tibiis anticis intus subarmatis, 

 femoribus posticis haud dentatis ; autennis versus basin runs. Long. '18. 



Platte river, under dried buffalo excrement. Differs abundantly from M. dentl- 

 collis by the absence of serration on the sides of the thorax, as well as by the 

 posterior femora being not armed with a tooth ; the scales of the upper surface of 

 the body are broad. 



The genus Myoclirous consists of elongated pubescent Eumolpi, in which the 

 thorax is slightly lobed behind the eyes; the latter are small and prominent; the 

 antepectus is excavated for the reception of the head ; the claws of the tarsi are 

 not perceptibly toothed. The anterior tibiae are armed with a more or less promi- 

 nent denticle on the inner surface near the middle ; the posterior femora are some- 

 times simple, and sometimes toothed. 



4i;i>IO\Y4 HIS LATR. 



<E. lilgens, elongato-ovalis, atra opaca, thorace elytrisque anguste marginatis, illo disperse punc- 

 tato,, ad basin late rotundato, abdominis segmentis dorsalibus pallidis. Long. -21. 



Santa Fe, Mr. Fendler. Of the same shape, but smaller than CE. concinna 

 (Hallica concinna Fabr.), and easily known by its dull opaque black color, and by 

 the base of the thorax not being sinuate near the posterior angles. The elytra 

 appear irnpunctured ; the pale color of the dorsal surface of the abdomen shows a 

 little beneath at the margin and tip. 



<E. lohala. pallida, thorace angulis anticis acutis, lateribus late reflexis, elytris nigro-piceis subti- 

 liter punctatis, basi versus scutellum latius, margine lateral! trilobate, maculisque utrinque duabus 

 disci pallidis, sutura anguste pallescente ; subtus fusco-testacea, pedibus pallidis. Long. - 20. 



One specimen from Kansas river. Allied to CE. quercata, but larger, and with 

 the elytra less broadly margined ; the arrangement of the colors on the latter is 



also very different. 

 



HALTTCA ILLIGER. 



H. punctigera, oblongo-ovalis, pallide flava, thorace latitudine duplo breviore, punctulato, late- 

 ribus rotundatis marginatis, dorso convexiusculo, punctis 4 nigris notato (externis saipe deficieii- 

 tibus), elytris dense subtiliter punctatis, sutura, vitta discoidea apicem haud attingente, alteraque 

 juxta marginem nigris, tibiarum apicibus, tarsis antennisque fuscis, his articulis tribus primis 

 subtus flavis. Long. -30. 



Kansas, near the Rocky mountains. Belongs with a numerous series of species 

 allied to H. aUernata ; it is broader than that species, the thorax is more convex 

 and more rounded on the sides; and the elytra are finely, but strongly and densely 

 punctured.
