350 Goleopterological Notices, VII. 



G. tlioracica n. sp. — Eatber stouter than jamis, but similar in color 

 and vestiture. Head mucb longer than wide, broadly subtruncate and rounded 

 at base, the sides becoming nearly parallel behind the eyes; antennse long and 

 rather thick, the basal joints unusually long. Prothorax large, a little longer 

 than wide, similar in form to that of janus but more finely and densely punc- 

 tate and pubescent. Elytra black with scarcely a trace of violaceous reflection, 

 dull, % longer than wide, slightly more than twice as wide as the prothorax 

 and about three times as long ; outline and sculpture nearly as in janus, the 

 pubescence a little denser. Under surface blackish, the prosternum, pro- 

 pleurse and legs pale throughout. Length 21.0 mm. ; width 7.0 mm. 



Florida. 



Differs from janus in its larger size, and especially in its much 

 larger and more finely and closely sculptured prothorax. The 

 joints of the antennse are relatively more elongate, and the first 

 is less narrowed at base and less clavate. 



G. iiifirina n. sp. — Color as in calif ornica, the body smaller and less 

 elongate. Head but slightly elongate, similar at base, in sculpture and in the 

 large rufous central spot to californica ; antennse but slightly more than J^ as 

 long as the body. Prothorax relatively small, but slightly wider than the 

 head, somewhat longer than wide, nearly similar to that of californica, but 

 with the sides more reflexed toward apex and less convergent and more feebly 

 sinuate toward base. Elytra unusually short, 3i longer than wide, 2% times 

 as wide as the prothorax and only 3 times as long, distinctly wider behind the 

 middle than at base; strise quite coarse and somewhat impressed; punctures 

 fine and close-set. Length 14.0 mm. ; width 5.0 mm. 



Arizona (Yuma). Mr. Dunn. 



Allied to californica, but differing very much in its shorter, 

 more coarsely striate elytra and smaller prothorax. The pubes- 

 cence is in great part rubbed off from the basal and sutural parts 

 of the elytra, but that which remains does not seem to be erect 

 as it is in californica and lecontei, which last appear to be 

 mutually different. This is much the smallest species of the 

 genus within our territorial limits, as tlioracica is the largest. 



There are before me two well marked geographic subspecies of 

 hicolor; the first, which maj^ be called obliqua, being larger and 

 stouter than the normal forms, though nearly similar in other re- 

 spects, except that the prothorax is narrowed anteriorly from a 

 point more posterior ; it occurs in the extreme southern parts 

 of Florida, the specimens in my cabinet being from Lake Worth. 

 The second is represented by an example somewhat smaller than 

 the typical forms, with relatively shorter elytra and more ab- 

 breviated prothorax, the latter not longer than wide, and the head
