SPAENUS. 451 



1. Sparnus chiriquensis. (Tab. XXVI. fig. 23.) 



Broadly ovate, dark reddish fulvous ; the six apical joints of the antennas black ; the extreme lateral margin 

 of the elytra and the tarsi testaceous ; thorax remotely puuetured ; elytra deeply punctate-stnate. 



Simpur^the frontal tuhercles divided by a deep longitudinal .groove ; the palpi moderately W 

 sate antenna, less than half the length of the body, the third joint the longest, the ast six joints 

 Averse Tbort and blaek; thorax about three times as bread as long, the sides very slightly rounded 

 bXre the middle the posterior margin sinuate and broadly rounded and produced near the middle, the 

 afteriorangrooUqnely rounded, the surfaee without depressions, distantly punctured; elytra very 

 Lnvex without a Lai depression, very strongly pnnctate-striate, of a reddish fulvous colon, • (like 

 the rest or the body), the extreme lateral margin thickened, testaceous; postenor tibne with a double 

 spur. 



Bab. Panama, Volcan de Chiriqui (Champion). A single specimen. 



It seems to me that the length of the posterior femora and tibia, which served Clark 

 as a distinguishing character between the genus Sparnus and Cyrton, is of little, if any, 

 value as the sexes frequently differ in that respect in the same species ; the simple or 

 appendiculate claws are, however, characters which may be used with advantage. 



2 Sparnus apicalis. (Tab. XXVI. fig. 24.) 



Subglobose, glabrous, convex, below fulvous ; lower part of the face, the antenna, and tibi* flavous ; head 

 and thorax black; elytra sanguineous, their apices black ; femora black. 



^flltf Imall fovea at the middle of the vertex, the latter with a few minute punctures, black ; the lower

Led the third ioint longer than the first, the two following ones nearly equal m length, the sixth joint 



hickened bug and of cylindrical shape, the rest short ; thorax three times as broad a, long, the sides 



^TSS the anterior angles obliquely truncate, the surface nearly impunctae, black the basal 



m^Sa^ith rufous; elytra without a basal depression, regularly and strongly punctate-stnate, 



Apices nf ar ; impunctie, i a bright blood-red colour, the apices with * tr", ta-g*^ 



shaped black band; femora black, the posterior ones sometimes rufous below; posterior tibiae armed 



with a single strong spur; claws appendiculate. 



Hab. Panama, Bugaho, {Champion). 



In one specimen, probably immature, the colour of the elytra is flavous instead of 

 red, but the apices are as in the typical form. 



3 Sparnus flavicollis. (Tab. XXVI. fig. 25.) 



Broadly ovate, glabrous, flavous; head and thorax impunctate; elytra bright red, shining, finely punctate- 

 striate, the interstices obsoletely costate ; legs flavous, the posterior femora red. 



Length 2 lines transverselv „ r00 ved between the eyes; the frontal tubercles scarcely indicated; palpi 

 ^S^Sl^ate joint; anlnme flavous, stout and rather short, the fir^omt

 Xng j intstSLrand longer, the rest short, gradually thickened ; thorax three times as broad as 

 W the ides angulate before the middle, the surface flavous, impunctate ; scutellum flavous; elytra
