base ; the elytra are scarcely punctulate ; the antennae and feet are entirely 

 black.

Texas ; I owe three specimens to the liberality of Mr. Ulke. This species 

 differs from all the preceding by the third joint of the antennae being scarcely 

 longer than the second, and both united are not longer than the fourth. I 

 infer from European works that it represents the genus Calomicrus 

 Stephens, of which Redtenbacher observes, that he finds no difference between 

 it and Luperus, except the equality of the second and third joints of the 

 antennae in the former. 



In the three specimens before me, the ventral segments 1 4 are nearly 

 equal in length, and the fifth is much longer, marked with two distant deeply 

 impressed lines extending from tbe hind margin nearly to the base of the 

 segment. The antennae are more than two-thirds the length of the body, and 

 I consider them all as males. 



AGELASTICA. Redt. 



The body in this genus is ovate and convex, resembling in form e d i o n y- 

 chis among the allies of Haltica. The head is deeply channelled between 

 the eyes, and the usual transverse siuuated line is faint ; the front between 

 the antennae is scarcely elevated. The antennae are rather long and stout, 

 with the second joint half as long as the first, the third is a little longer than 

 the second, and both together are longer than the fourth. The maxillary 

 palpi are very stout, the last joint is shorter than the preceding, conical, 

 scarcely longer than its width at base. Prothorax transverse, broadly 

 emarginate in front, and rounded at base, with the angles not prominent. 

 The disc is marked each side with a deep excavation. Elytra convex, dilated 

 behind, obtusely rounded at tip, marked with two foveae at base ; epipleuras 

 distinctly defined, extending to the tip ; lateral margin thick and obtuse 

 toward the tip. Anterior coxae conical, prominent, contiguous ; tibiae not 

 sulcate externally, ungues with a broad angular basal dilatation. 



The characters of this genus are not very well defined, but its more robust 

 form and stronger sculpture will enable it to be readily distinguished. 



1. A. hale ns is, rufo-testacea, occipite cyaneo, thorace transverso nitido, 

 utrinque profunde excavato. elytris laete cyaneis, fortiter licet subtiliter 

 punctatis, autennis nigris, pedibus rufis, tibiis apice tarsisque nigro-piceis.

 Panz., &c. 



Two specimens of this common European species were given me as col- 

 lected at Farinington, Connecticut, by Mr. Edward Norton. 



GASTROGYNA Lee. 



Body different in form in the two sexes, above glabrous, nearly smooth. 

 Head with a short medial impressed line between the eyes ; front before the 

 antennae transversely broadly impressed, labrum large, not emarginate. 

 Maxillary palpi slender, last joint longer than the preceding, pointed at tip. 

 Antennae long and rather stout, second joint one-third as long as the first, 

 third somewhat shorter than the fourth ; eyes small, rounded, not very promi- 

 nent. Prothorax transverse, truncate in front and behind, sides nearly 

 straight, front angles prominent, but rounded at tip, hind angles- not promi- 

 nent, slightly obtuse. Elytra elongate and parallel in the male, wider
