 tL\ caualiculata, tliorace latitudiue baud longiore, lateribus rotundatis, ad basin late rotuudato, 

 puiictato subrugoso versus apicem sublaevi, elytris longiusculis, convexis, thorace latioribus, striis 

 baud impressis antice punctatis postice obsoletis, interstitiis alutaceis parce punctulatis. Long. -20. 



One specimen found at Foi't Laramie. 



MYOCHROrS. 



ITI. sqiiainosilS, loDgiusculus, piceo-Eeneus, dense griseo-squamosus, breviter pubescens, capite 

 tboraccque confertissimc punctatis, boc subrotundato, lateribus baud dentatis, elytris tliorace non 

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

 femoribus posticis baud dentatis ; antennis Tersus basin rufis. Long. -18. 



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

 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 Mijochrous 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 tibifc 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. 



CEDIOJIYCHIS Latr. 



<E. llig'ens, elongato-ovalis, atra opaca, tborace elytrisque auguste marginatis, illo disperse punc- 

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



Santa Fe, Mr. Fendler. Of the same shajoe, but smaller than CE. concimia 

 [Haltica 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 el^'tra 

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

 little beneath at the margin and tip. 



ffi. lobata, pallida, tborace angulis anticis acutis, lateribus late reflexis, elytris uigro-piceis subti- 

 liter punctatis, basi versus scutellum latins, margine laterali trilobato, maculisque utrinque duabus 

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



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

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

 also very different. 



HAIiTICA Illiger. 



H. piinctig'Cl'a, oblongo-ovalis, pallide (lava, tborace latitudine duplo breviore, punctnlato, late- 

 riljus rotundatis marginatis, dorso convexiusculo, punctis 4 uigris notato (externis SiEpe deficien- 

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

 juxta marginem uigris, tibiarum apicibus, tarsis antennisque fuscis, bis 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.
