344 Coleopterological Notices, VIZ. 



In latipennis, the sides of the prothorax are parallel and quite 

 evenly arcuate throughout, and the edges of the elytra behind 

 the humeri are said to have a few serrations, of which there is no 

 trace in arcuata ; at the same time, however, there is no trace of 

 them discoverable in the single specimen before me from Tulare 

 Co., California, which I have assumed to represent latijyennis. 



Notes. — Of calida, a species of extended distribution, I 

 have before me specimens which seem to represent rather well de- 

 fined subspecies. One of these, from Lake Superior, which I 

 have called stellata, is similar[_in form to the typical calida, but 

 has the elytral striae quite feeble, with the greenish-golden spots 

 very large and brillant and more approximate than in the normal 

 forms. Another, from Keokuk, Iowa, which may be named ex- 

 pansa, has the prothorax very large, with the sides very broadly 

 reflexo-explanate and distinctly greenish-metallic in lustre ; the 

 elytra in the male are onlj^ a fourth wider than the prothorax, but 

 quite similar in every other respect to those of the normal forms, 

 except that the coppery spots are smaller. A third, from Las 

 Vegas, New Mexico, which may be denominated laticollis, has 

 the body larger, broader and less convex than in the normal 

 forms, the elytra more parallel and only just visibly wider behind 

 the middle than at base ; the antennae are deep black throughout, 

 and do not become pale toward apex as in the usual forms, and 

 the coppery spots of the elytra are obscure. 



In a similar manner with regard to sayi, I have taken specimens 

 at the electric lights in Norfolk, Ya., which represent quite a 

 marked subspecies ; it is narrower, with the middle tibiae of the 

 male less bent and the pubescent pad of the first tarsal joint en- 

 tire ; in the larger western forms of sayi, this pad is divided 

 along the median line by a glabrous area. This subspecies may 

 be called virginica. 



A female specimen from Indiana appears to form a subspecies 

 of frigida, which may be named levettei. It is similar in form 

 and sculpture to the normal forms, but is a little more elongate, 

 with a smaller and less transverse prothorax, which has no trace 

 of the concave lateral margin of frigida, the surface being even in 

 curvature to the reflexed marginal bead ; the disk is distinctly 

 less than twice as wide as long. In the typical forms the surface 

 of the elytra has a feeble violaceous lustre, but in levettei the en- 

 tire surface is deep black.
