PEECILESTHUS.—STRONGYLIUM. 341 
rated by the impressed head, more convex thorax, testaceous scutellum, much finer and 
more lightly impressed elytral strie, slightly convex and closely punctured interstices, 
shorter legs, &c.; and also by the maculation of the elytra. 
9. Pocilesthus maklini. (Tab. XIV. fig. 15, 3.) 
Oblong ovate, moderately convex, testaceous, shining. Head very sparingly and minutely punctured, the 
vertex unimpressed; antennz moderately long, gradually widening outwardly, joints 5-10 subtriangular, 
much longer than broad, almost equal in length, the apical joint ovate and as long as but rather narrower 
than the tenth, joints 7-11 black, the basal halves of 4~6 stained with piceous, the rest (and the extreme 
apex of the eleventh) testaceous or fusco-testaceous; prothorax strongly transverse, moderately convex, 
the base feebly bisinuate, the apex nearly straight, the sides feebly rounded and but little narrowing in 
front, the anterior angles rounded, the base deeply grooved within in the middle, the basal fovese mode- 
rately deep, the surface sparingly but very distinctly punctured on the disc, obsoletely so towards the 
sides, the middle of the base slightly stained with piceous; scutellum smooth, piceous; elytra compara- 
tively rather short, moderately convex, subparallel in their basal half, rather shallowly punctate-striate, 
the interstices flat and rather closely but very minutely punctured, the suture (except at the apex) 
and a longitudinal patch (placed about the middle and extending from the third to the eighth interstices) 
on the disc of each piceous ; beneath smooth, impunctate, the epipleure stained with piceous; legs rather 
long and slender, the apices of the femora and the outer edges of the tibie stained with fuscous, the tarsi 
with piceous; anterior tibie in the male strongly curved (the intermediate pair also but not so distinctly), 
and with the inner margin thickly clothed with hair. 
Length 74 millim.; breadth 3 millim. (¢.) 
Hab. Guatemaa, San Juan in Vera Paz 2000 feet (Champion). 
A single example of this distinct species was captured by myself on the forest-clad 
mountain-slope north of the Polochic valley. P. mdklini is perhaps nearest allied to 
P. immaculatus ; it is separated from that species by the thorax being more rounded 
at the sides and less narrowed in front; the elytral striz finer and not so deeply 
impressed, and the interstices quite flat; and also by the elytra being maculated.

Maklin in his monograph of this genus enumerates 266 species, of which 189 are 
from the New World; the 189 New-World species are apportioned thus:—North 
America 3, Mexico and Central America 36, South America 145, and the Antilles 
5. Since that time (1864) 39 additional species have been recorded, 5 only of 
which are from the New World, viz. 2 from Florida, and 3 from Tropical South 
America. 
A large number of undescribed forms, however, exist in’ collections, and the total
