522 RHYNCHOPHORA. 
GuatemaA, Cubilguitz in Vera Paz (Champion), Coban (Conradt); NicaRaeua, 
Chontales (Belt, Janson) ; Panama, Bugaba, Volcan de Chiriqui (Champion) .—CoLoMBIA 
(Mus. Brit.). 
Found in numbers in Chiriqui, under the sappy bark of fallen trees. The sexes are 
so different as to appear to be specifically distinct. The male is broader than the 
female, and has the prothorax more transverse, and very much smoother on the disc ; 
the anterior femora very stout and unarmed, the anterior tibie curved, with the apical 
spurs approximate (fig. 294). The female has the disc of the prothorax coarsely, 
sparsely punctate ; the anterior femora toothed, and the anterior tibie straighter, with 
the apical spurs more distant (fig. 30); the rostrum smoother at the tip. 
ZASCELIS. 
Zascelis, Leconte, Proc. Am. Phil. Soc. xv. p. 256 (1876). 
The species here referred to Zascelis are of elongate, oblong, or ovate shape, and 
have the general facies of a large Baris. They agree in the following characters :— 
Head convex, not carinate above the eyes, the latter almost or quite hidden in repose, depressed, coarsely 
facetted, and laterally placed ; rostrum strongly retractile, curved, subcylindrical, rather slender ; antenne 
inserted at or behind the middle of the rostrum, the funiculus 7-jointed, the club ovate or oblong-ovate ; 
prothorax broader than long, deeply bisinuate at the base, with prominent ocular lobes ; scutellum flat- 
tened or convex, the cavity large ; elytra wider than the prothorax, oblong, flattened on the disc, coarsely 
seriate-punctate, the humeri rounded and not prominent; rostral canal nearly or quite reaching the 
metasternum ; metasternum rather long, with broad episterna; ventral segment 2 longer than 3, 1 and 2 
free, or connate at the middle (Z. glabrata and Z. rugosa), the first suture straight or curved ; legs short, 
stout ; femora feebly clavate, unidentate, the intermediate and posterior pairs sulcate beneath; tibie 
broad and compressed, all sharply carinate on their outer edge, the carina sometimes broken up into teeth 
on the intermediate and posterior pairs; tarsal claws simple. 
In addition to the three species placed in this genus by Leconte, Zascelis will include 
Cryptorhynchus affaber, Boh., a common Central-American insect, and various new 
forms described below. C. geminatus, Boh., from Brazil, is a near ally of Z irrorata, 
Lec., but it has a shorter rostrum and subcontiguous eyes. Z. rugosa would be almost 
equally well placed in Metriophilus, and Z. glabrata will probably have to be separated 
eventually. 
a. Ventral segments 1 and 2 separated by a distinct, almost straight suture, 
2 a little longer than 3: body sparsely squamose. 
a’. Head without lateral sulci.
