convex, flatter towards the base. Anterior femora strongly clavate. Anterior tibie curved, moderately 
long, unguiculate, and armed with 5 or 6 small scattered teeth. Intermediate tibiz hollowed near the 
apex within in ¢. 
Length 54, breadth 24-23 millim. (d 2.) 
Hab. Guatemaua, San Gerénimo [ 2 ], Capetillo [| ¢ |] (Champion). 
Three specimens, assumed to be sexes of the same species, the female (taken as the 
type, fig. 23) being much broader than the Capetillo examples (males ?) and in very 
fresh condition. They all have a common, sharply-defined, undulate, whitish, subapical 
fascia, but the transverse patch on the disc varies in size, though very conspicuous in 
the female. The Capetillo specimens have slightly larger scales than the San 
Gerdénimo insect. The curled hairs on the upper surface are smaller, shorter, and 
much less conspicuous than in P. fasciatus when the two forms are viewed in profile. 
The elytral markings, too, in P. fasciatus show no tendency to coalesce into a common, 
well-defined, pallid, subapical fascia. 
29. Pandeleteius vitticollis, sp.n. (Tab. VIII. fig. 24.) 
Moderately elongate, piceous or obscure ferruginous, the legs and antenne partly or entirely rufo-testaceous ; 
variegated with a dense clothing of opaque whitish, pale brown, and fuscous (or blackish) scales, some of 
which have a faint cupreous lustre in certain lights, the dark scales on the prothorax almost wholly 
condensed into a broad median vitta, and those on the elytra into a narrow, oblique or angulate, subapical 
fascia (followed by a broader whitish one) and various irregular scattered spots or streaks; the upper 
surface also set with scattered, very minute, short, curled hairs, which are uniseriately arranged down 
each elytral interstice. Head and rostrum together about as long as the prothorax, finely punctate, the 
rostrum subquadrate, triangularly notched at the tip, slightly hollowed and feebly canaliculate down the 
middle, and with a very shallow transverse inter-antennal groove, the scrobes curved, narrow, and 
not descending to the lower surface; eyes somewhat prominent; joint 2 of the funiculus not longer 
than 3 and 4 united. Prothorax transverse, rounded at the sides, strongly constricted towards the apex, 
and constricted and much narrowed behind; sparsely punctate, the disc transversely depressed before 
and behind the middle; vibrisse long. LElytra at the base considerably wider than the base of the 
prothorax, widening to the middle and inflated posteriorly, strongly so in 9, transversely flattened on 
the disc anteriorly ; finely punctate-striate, the interstices becoming convex towards the apical declivity, 
Anterior tibie long, slender, feebly curved, unguiculate, armed with about 8 small teeth. Intermediate 
and posterior legs slender. 
Length 34-6, breadth 12-23 millim. (¢ 9.) 
Hab. Mexico (Mus. brit.), Refugio in Durango, Cordova (Hége), Amula (H. H. 
Smith); GuarEMALA, near the city (Salvin, Champion), Capetillo, San Gerdnimo, San 
Joaquin (Champion); Nicaragua, Managua (Solari); Panama, Volcan de Chiriqui 
(Champion). 
Numerous examples, including a long series from San Gerdénimo. This species may 
be known by the arcuately dilated, basally and apically constricted, fusco-vittate 
prothorax; the posteriorly widened, obliquely unifasciate, fusco-maculate, finely 
punctate-striate elytra; the long, slender, feebly curved anterior tibia ; and the slender 
intermediate and hind legs. The single example from Panama is much smaller than 
the others. P. vitticollis may prove to be inseparable from P. robustus, Schaeff., from
