PCECILESTHUS. 339 
5. Pecilesthus guatemalensis. 
Oblong ovate, rather convex, bright reddish-testaceous. Head coarsely and rather closely punctured, the 
anterior half much smoother, shallowly longitudinally impressed between the eyes; antenne rather short, 
widening outwardly, joint 6 the length of but much wider than 5, subtriangular, joints 7-10 decreasing 
slightly in length, wider than 6, 7 and 8 about as long as broad, the apical joint longer and narrower 
than the tenth, joints 1-5 and the extreme apex testaceous, the rest black; prothorax short, convex, 
strongly transverse, the sides a little rounded about the middle and narrowing anteriorly, the base and 
apex nearly straight, the anterior angles rounded, the basal foves very shallow, the surface coarsely and 
rather closely punctured; scutellum depressed in the middle; elytra moderately long, rather convex, 
subparallel in their basal half, shallowly striate-punctate, the interstices perfectly flat and each with about 
three rows of rather coarse punctures (the punctures nearly as coarse as those of the strie); beneath 
almost smooth, the flanks of the prothorax somewhat coarsely punctured; legs slender, unicolorous, 
testaceous ; anterior tibie in the male curved and sinuous, a little widened on the inner side towards the 
base, and with the inner margin clothed with short hairs. 
Length 6} millim.; breadth 24 millim. (¢.) 
Hab. GuatemMAa, Teleman (Champion). 
A single male example captured by myself in the Polochic valley. An obscure 
species, though abundantly distinct from any other of the genus known to me. 
6. Pecilesthus laticollis. (Tab. XIV. fig. 10, 2 .) 
Oblong ovate, moderately convex, testaceous or fusco-testaceous, shining. Head very finely and sparingly 
punctured, in one or two examples almost smooth, the vertex nearly or quite unimpressed, the eyes more 
or less piceous in tint; antenne ( Q ) comparatively short, widening outwardly, joints 6-8 subtriangular, 
8-10 equal in width but decreasing in length, the apical joint longer and rather narrower than the tenth, 
testaceous, joints 4-6 more or less stained with fuscous, 8-11 black, the extreme apex of the eleventh 
testaceous ; prothorax exceedingly short, twice as broad as long, slightly convex, very strongly mar- 
gined, the base feebly bisinuate, the apex nearly straight, the sides feebly emarginate about the middle 
and slightly narrowing in front, the anterior angles broadly rounded, the base deeply impressed within 
between the fovese, the surface very sparingly, shallowly, and finely punctured, much more coarsely so on 
the basal portion of the disc, the basal half of the disc and the margins usually stained with piceous ; 
scutellum more or less stained with fuscous or piceous, sparingly punctured; elytra moderately long, 
feebly convex, subparallel in their basal half, rather deeply punctate-striate, the interstices feebly convex 
and finely and sparingly punctured, the shoulders, a rather large patch on the disc (sometimes represented 
by a short oblong streak on the second and fourth interstices) of each near the base, a transverse band of 
longitudinal streaks about the middle (these streaks placed on the alternate interstices from the second to 
the eighth, that on the second being very much the longest), a streak on the second interstice near the 
apex, and a triangular patch at the point of junction of the third and sixth striw, piceous or black; 
beneath almost smooth, the sides of the meso- and of the metasternum and side-pieces, and the epipleure, 
sometimes stained with piceous; legs moderately long, the apices of the femora, the tibie and tarsi more 
or less stained with fuscous. 
Length 62-8 millim.; breadth 22-33 millim. ( 9.) 
Hab. Mzxico, Cordova (Sallé), Tapachula in Chiapas (Hoge); GuaTemaLa, Zapote 
(Champion). 
Var. The elytral markings obliterated, the rest as in the type. 
Hab. Guatemata, Zapote (Champion). 
Six female examples. This species is allied to P. decem-signatus, Makl., and some 
undescribed forms from Tropical South America. ‘The exceedingly short, broad, and
