20. Collops intermedins. 



Collops intermedins, Gorh., Biol. Centr.-Am., Coleopt. iii, 

 2,p. 315(c^$). 



(^. Antennae with joint 1 curved, much widened outwards, 

 rounded at tip ; 2 with a short, slender appendage, which is entirely 

 received in repose in the large cavity. 



Hab. Panama, Chiriqui, Panama, 



Extremely like C. histrionicus, but distinguishable there- 

 from by the shorter and more slender appendage of the 

 second antennal joint of the male. The head in both sexes 

 is testaceous between the points of insertion of the antennae. 

 The basal joint of the latter is streaked with black in the 

 female and sometimes in the male also. The more shining 

 surface, deeper colour, and less densely punctate elytra, 

 characters relied upon by Gorham, are of no value, when 

 series of the two forms are compared. The head is some- 

 what deeply transversely depressed anteriorly in the male, 

 obsoletely so in the female. A female from Los Frailes, 

 Costa Rica {Mns. Brit.), with entirely dark head, may 

 belong here. 



[Collops tibialis. 



Collops tibialis, Schaefi., Canad. Ent. xliv, p. 186; Fall, 

 Journ. N. York Ent. Soc. xx, pp. 254, 271. 



(J. Antennae with joint 1 curved, moderately widened outwards, 

 convex within, rounded at the outer apical angle; 2 broader than 

 long, angularly dilated at about the middle externally, the appendage 

 long and slender. 



Hab. United States, Arizona and New Mexico, 

 Antennal characters taken from a male from Chiricahua 

 Mts., Arizona, sent by Mr. Fall. This insect has the 

 yellow anterior portion of the head trilobate behind, and 

 the large blue elytral spots longitudinally confluent.] 



21. Collops varipes, n. sp. 



(J. Rather short, shining, nigro-caeruleous, the head around and 

 between the points oi insertion of the antennae and in the middle 

 anteriorly, the labrum and clypeus, the bases of the mandibles 

 and palpi, the antennae, the prothorax, the elytra in part (except 

 a rather broad, common fascia at the base, and a large subapical 

 spot reaching the outer margin), the abdomen, tibiae and tarsi
