602 SEERICORNIA. 



The elytral punctuation is finer than in that species. The apical red patch is very 

 sharply defined. The elytra appear to be clothed with intermixed cinereous and 

 brownish hairs. 



PRIONOSCIRTES. 



Head very broad, deflexed ; maxillary palpi with, the apical joint oval, pointed at the tip ; labial palpi with 

 the apical joint oval, arising from near the base of the second joint, and at a right angle to it ; antennas 

 serrate, joint 1 stout, oval, dilated on the inner side, 2 and 3 very short, 2 moderately stout, globose, 

 3 narrower and subtriangular, 4-11 rather elongate, flattened, and somewhat dilated, subparallel towards 

 their apex, gradually decreasing in length ; hind coxae contiguous along the median line, the dilated inner 

 portion of the coxal plates transverse oval ; legs as in Scirtes. 



The extraordinary little insect from Guatemala from which the above characters are 

 taken may be described as a Prionocyphon with the saltatorial hind legs of a Scirtes, 

 and the hind coxae of a Helodes or Cyphon. The antennae are formed as in Priono- 

 cyphon, except that the basal joint is less dilated. The hind tibiae are shorter than in 

 most of the species of Scirtes of the same size. The species has quite the facies of the 

 European Prionocyphon serricomis, but it is very much smaller. 



1. PrioilOSCirteS Saltitans. (Tab. XXVI. figg. 23; 23a, antenna; 23 5, 

 hind leg.) 



Rotundate-elliptic, very convex, shining ; rufo-testaceous, the eyes black, the antennae and legs testaceous ; 

 clothed with fine yellowish pubescence. Head and prothorax sparsely, exceedingly minutely punctate ; 

 eyes moderately large and not prominent ; antennae about, three-fourths the length of the body ; prothorax 

 very short and convex, the margins not visible from above ; elytra thickly, minutely punctate, the punc- 

 tuation much more distinct than that of the prothorax ; hind tibiae slightly bowed inwards and rather 

 short, about equalling the femora in length, the upper spur about two-thirds the length of the first tarsal 

 joint, the lower spur small.

One specimen, probably a male, from the lower slope of the Volcan de Fuego.

This name * is retained for various species which differ from Scirtes as follows : — 

 Posterior coxae contiguous in front only along the median line, separated posteriorly 

 by the raised intercoxal process of the abdomen, less abruptly dilated inwards, the 

 inner portion not forming a subquadrate plate as in Scirtes ; middle coxae contiguous 

 behind, or separated by a very thin lamina ; prothorax and elytra explanate and 

 acutely margined at the sides. The head is margined at the sides below the eyes, as 

 in many Scirtes. Clark, who described the tibiae as unarmed and did not observe the 

 form of the coxae, referred this genus without hesitation to the Halticida3, but its true
