76 Mr. G. C. Champion's Revision of the Mexican 



Moderately elongate, widened posteriorly, shining; varying in 

 colour from black, with the elytra (a transverse patch at the base 

 of each elytron excepted), the outer edge of the two basal joints of 

 the antennae, and the legs and abdomen in great part testaceous 

 to testaceous, with a humeral spot, the posterior legs in part, the 

 antennae (except at the base), and the tips of the palpi black; 

 finely, sparsely pubescent and also somewhat thickly set with long, 

 suberect, pallid hairs. Head broad, transverse, closely, minutely 

 punctate; antennae rather short in both sexes. Prothorax trans- 

 verse, convex, minutely punctate. Elytra widened posteriorly, a 

 little broader than the prothorax at the base, rather sparsely, 

 minutely punctate. Legs slender; posterior tibiae curved in both 

 sexes. 



(J. Anterior tarsi apparently 4-jointed, the prolonged upper 

 portion of the fused joints 1 and 2 about reaching the apex of 3; 

 posterior tibiae slightly produced at the apex. 



$. Posterior tibiae produced at the apex into a long dentiform 

 process, which reaches as far as the apex of the first tarsal joint. 



Length 2-2 J mm. (c?$.) 



Hab. Guatemala, Mirandilla {Cham/pion : $) ; Nica- 

 ragua, Chontales {Janson : ^^); Panama, Taboga Island 

 {Champion : $). 



Three females and one male. The pair from Chontales 

 ^re taken as the types, the male differing from the female 

 in having the head testaceous to near the base. The 

 Guatemalan example ($) has the sides of the prothorax 

 broadly and a large humeral patch nigro-piceous ; the 

 Taboga specimen ($) is testaceous, with a black humeral 

 spot. Anthocomus fuscescens (^ calcaratus) (Gorh.), has 

 similar posterior tibiae in the female, but the male of that 

 insect has simple 5- jointed anterior tarsi. In the unique 

 male of the present species the basal joint of the anterior 

 tarsi cannot be distinguished for certain, it being either 

 extremely short or fused with the second. 



51. Attains coelestinus. 



Attains coelestinus, Gorh., Biol. Centr.-Am., Coleopt. iii, 

 2, p. 320. 



(J. Anterior tarsi with jomts 1-3 somewhat thickened, 1 short, 

 3 as long as 2, 4 small, 2 rounded at the apex as seen in profile; 

 antennae moderately long, serrate. 



$. Antennae shorter and more slender.
