456 PHYTOPHAGA. 



and the following joints of equal length, rather short, the third joint slightly longer ; thorax slightly 

 loDger than broad, narrowed in front, the sides very little rounded before the middle, the surface ferru- 

 ginous, thickly clothed with yellow hairs which conceal the punctuation ; elytra distinctly narrowed 

 behind, of a dark fuscous colour at the disc, the sides obscure fulvous, the suture very narrowly clothed 

 with a thin pale flavous pubescence in the shape of a stripe which widens at the apices into a triangular 

 patch, a similar but still more obscure stripe extends obliquely from the shoulder to below the middle ; 

 legs fulvous ; posterior tibiae armed with a single spur ; claws bifid. 



Eab. Panama, Bugaba (Champion). A single specimen. 



This species differs from any of those described by Clark in its coloration in 

 connection with the size; the elytral pale stripes can only be seen when the insect 

 is viewed sideways, the punctuation is close and distinct, gradually diminishing 

 posteriorly. 



3. Khinotmetus albopilosus. 



Black ; antennae fulvous, the two basal and the sixth, seventh, and eighth joints, and the apical one, piceous ; 

 thorax granulate-punctate, with a lateral stripe of white pubescence ; elytra deeply punctate-striate, the 

 interstices strongly costate, sparingly clothed with silvery-white hairs. 



Length 1| line. 



Head granulate at the vertex, with a short longitudinal tubercle between the eyes, the latter very large ; the 

 lower part of the face obscure testaceous, glabrous, forming nearly a plane surface; palpi filiform; 

 antennee nearly half the length of the body, the last six joints short and thicker than the others ; 

 thorax subquadrate, the sides deflexed anteriorly, the lateral margins very obsolete, somewhat rounded 

 and produced anteriorly, the surface entirely granulate, black, the sides clothed with silvery-white pubes- 

 cence in the shape of a longitudinal stripe ; elytra deeply depressed below the base, black, shining, the 

 entire disc very strongly and longitudinally costate, the interspaces strongly punctured, sparingly clothed 

 with silvery pubescence which assumes the shape of a spot at the middle, more distinctly pubescent at the 

 sides ; femora black, sparingly pubescent ; tibia? piceous, the posterior pair armed with a double spur. 



Eab. Panama, Bugaba (Champion). 



This species is sufficiently distinguished by its black colour, the costate elytra, and 

 the white pubescence. One specimen, which differs from the type in having the elytra 

 piceous with the sides fulvous, instead of black, is probably immature ; other differences 

 I cannot find. 



4. Khinotmetus canescens? 



Rhinotmetus canescens, Clark, Cat. of Halticidae, p. 52 (1860) 1 . 

 Eab. Guatemala, Capetillo (Champion). — Brazil 1 . 



A single specimen of a MMnotmetus from Capetillo answers so nearly the description 

 of B. canescens, Clark, that I must refer it to that species. The entire insect is clothed 

 with yellow pubescence ; the head, thorax, and legs are flavous, but the elytra are dark 

 fulvous, thickly clothed with yellow hair which just allows the punctuation to be seen. 

 The antennae are half the length of the body and dark fulvous, but what Clark means 

 by saying that they are " contiguous at the base " I cannot quite understand ; no such 

 structure is known to me amongst the present section. In the specimen before me the
