‘TARPELA. 297 
Kight examples. This species is allied to 7. atra, from which it is separated by 
the longitudinal impressions on the elytra being much shorter and finer (not coarser 
outwardly as in 7. atra) and confluent (thus forming strie); the legs are pubescent, the 
femora still more closely and coarsely punctured; the prosternum, though similarly 
declivous, is armed with a short conical tubercle at the apex (in 7. atra it is almost 
simple), &c. 
17. Tarpela hogei. 
Closely resembling 7’. jalapensis, and differing as follows:—The head shorter, more confluently punctured, the 
frontal impression deeper; the antenne more slender, the third joint comparatively much longer, reddish- 
brown in colour, the three apical joints darker; the prothorax shorter and more transverse, the apex still 
more feebly emarginate, the anterior angles less prominent and obtuse, the sides not sinuate before the 
base but gradually narrowing to the obtuse hind angles, the punctures more or less confluent; the elytra 
with the base straight in the middle, the humeri obliquely cut off and not prominent and broadly and 
‘shallowly impressed within, the rows of confluent elongate impressions rather more deeply impressed, 
the interstices much more finely and more sparingly punctured; the legs more slender, though (including 
the femora) equally coarsely punctured; the prosternum only slightly transversely raised at the extreme 
apex. 
Length 82 millim. (@.) 
Hab. Mexico, Ventanas (H6ge). 
One example. From 7. oblonga and T. socia it will be known by its less prominent 
humeri, more coarsely punctured femora, complete epipleure, &c. 
18. Tarpela setigera. (Tab. XIII. fig. 4, 2.) 
Elongate ovate, subparallel, narrow, dark reddish-brown, with a slight bronzy tint, slightly shining, sparingly 
clothed with short bristly hair. Head long, shallowly transversely impressed in front, very closely, equally, 
and rather coarsely punctured; antenne (female) short, closely punctured, dark reddish-brown, the basal 
joint red; prothorax rather narrow, transverse, convex, very narrowly margined, the sides rounded, widest 
about the middle, very feebly sinuate behind, and a little more narrowed towards the base than in front, 
the angles obtuse, the apex feebly emarginate (straight when viewed from above), the surface very closely, 
coarsely, and equally punctured, the disc with a smooth central line in the basal half, the base almost 
straight, the basal fovew indistinct; elytra considerably wider than the prothorax, long, subparallel, the 
base truncate in the middle, the humeri rounded, with rows of short, longitudinal impressions, the 
impressions closely placed, somewhat coarse and deep, and not coarser outwardly, the interstices very 
slightly convex and very finely and sparingly punctured ; legs (including the femora) closely, coarsely, and 
roughly punctured, thickly clothed with very short hairs ; beneath pubescent, sparingly and somewhat 
coarsely punctured, the metasternum more coarsely and closely so at the sides, the flanks of the prothorax 
confluently punctured ; prosternum rounded off and declivous, the apex not produced; mesosternum very 
shallowly excavate; epipleure extending to the apex of the elytra. 
Length 9 millim.; breadth 33 millim. ( 2.) 
Hab. Mexico, Cordova (Sallé). 
One example. This species in its general form, and in the shape of the thorax, 
prosternum, &c., nearly agrees with 7. atra; it differs from that insect in being clothed 
with short bristly hairs, and in this respect somewhat resembles 7’. hispidula.
