CALOSOMA SUBAENEUM Chaud. 



ORIGINAL DESCRIPTION. 



[Translation.] 



Length 17 mm. Like discors in form, but more narrow and much smoother. Head 

 very slightly punctate, base and anterior margin smoother, impressions of face heavier. 

 Thorax a little smaller, very finely and irregularly -wrinkled above, more punctured 

 toward sides and the base and especially towards the posterior angles which are less 

 prolonged backward, more broadly rounded, sides of base very hollow near the angles, 

 lateral margin renexed, especially backward. Base of elytra almost as broad as 

 thorax, broadening toward the middle and rounding somewhat to the end. one half 

 longer than broad, humeral angles more square although rounded; anterior part of 

 sides rectilinear, less convex above; striae not impressed, composed of rows of small 

 dots, moderately near each other, from each of which a very small transverse wrinkle 

 covers the interstices; these dots and transverse wrinkles are more prominent at the 

 sides and near the end and give the outer border a very wrinkled appearance. Shin- 

 ing black the upper side slightly tarnished; sides and base of thorax as well as all 

 surface of the elytra, olive green bronze; on each are three rows of dots, slightly 

 larger than those on the striae, the first two are obsolete near the base. As it differs 

 from all other species on account of the sculpture of the elytra and also by its narrowed 

 form I have placed it provisionally at the end of the series. 



One specimen reported from California by M. Lorquin. 



This species was described as above by Baron De Chaudoir in 

 1869. * It occurs in California, Idaho, and Washington. 



CALOSOMA MONILIATUM Lee. 



(Syn.: C. laqueatumJjec.) 



ORIGINAL DESCRIPTION. 



Obscurely bronze, dark, head and thorax closely rugose and punctate, the thorax 

 twice shorter than broad, somewhat narrowed posteriorly, sides moderately rounded, 

 margin scarcely reflexed, base broadly emarginate. angles slightly produced, elytra 

 one-half longer than broad, closely grooved, calli on both sides smooth, oblong, and 

 pits arranged in triple row. Length .65. Oregon. ' Length 17 mm. Oregon. Mon- 

 tana. 



Longer than rest, about the size of Carabus serratus Say. 



This species was described by LeConte in 1852. 2 



In 1860 LeConte 3 described Oalosoma laqueatum (Proc. Phila. 

 Acad. Nat. Sci.; vol. 12, p. 318), but later reduced it to a synonym 

 of moniliatwm. C. mon'diatum occurs in Arizona, California, Idaho, 

 Montana, Nebraska, Oregon, Washington, and in the Northwest Ter- 

 ritory, Canada.
