AND EASTERN NEW MEXICO. 27 



Fort Laramie. I have given the name Glyptina to a group of Ilalliciv interme 

 diate between genuine Ilaltica and Longilarsus. The head is marked with a deep 

 oblique line each side between the eyes, running forward to the frontal elevation : 

 the antennae are half as long as the body, slightly thickened externally; the 2d 

 and 3d joints equal in length : the thorax is quadrate, transverse, with the anterior 

 angles obliquely truncate, the disc moderately convex, without impressed lines. 

 The elytra oblong, wider than the thorax, with rows of punctures ; the hind tibitc 

 deeply sulcate above, with the edge of the groove very finely serrate, the terminal 

 spur small, the tarsi attached at the end of the tibiae, 1st joint equal to the others 

 combined, and nearly half as long as the tibiae. Besides the two species here 

 described, the Californian Ilaltica cerina Lee., Pacific R. R. Expl. and Surveys, 

 vol. xi, insects, 68, also belongs to this genus. 



CJ. lissotorqiies, tcstacea, nitida, fronte parum clcvata, vertice titrinque oblique sulcato, thorace 

 transverse, basi rotundato, lateribus parallclis, angulis antieis oblique tnmcalis, iiitido, Isevi, vix 

 obsolete parce punctulato, elytris oblongo-ovalibus, tlioracc latioribus, fortitcr punctato-striatis ; 

 antennis extrorsum vix infuscatis. Long. 08. 



One specimen with the preceding, which it entirely resembles, except in the 

 sculpture of the head and thorax. It is also found in Pennsylvania.

Fort Laramie. Broader than C. denticulate, and differing therefrom in many 

 particulars. I have retained the older name for this genus, as I know no reason 

 for the substitution of Redtenbachcr s Plcctroscdis, which is adopted by many 

 naturalists of Germany and France.

Santa Fe, Messrs. Kern and Fendler. Of the form and size of L. mcraca ( Galle- 

 ruca meraca Say), but known by the uniform color of the feet, the less distinctly 

 punciulate elytra, and the less rounded sides of the thorax.

Fort Rilcy, Mr. Xantus. Closely related to M. vittafa, but differs by the sides 

 of the thorax being entirely straight, as well as by the colors ; the thorax is very 

 narrowly margined with black, but is yellow both above and beneath, as is also the
