PANDELETEIUS. 205 
from Salazar. A rather depressed form, with a mesially vittate, undulate, subtubulate 
prothorax; narrowly and obliquely bifasciate elytra, the suture of which is set with 
long hairs on the apical declivity in the female; the under surface pilose ; and some- 
what closely denticulate anterior tibia. 
34. Pandeleteius microcephalus, sp. n. 
Moderately elongate, narrow, nigro-piceous, the antenne and the tips of the tarsi ferruginous; thickly 
clothed with small brown scales, with a few whitish scales intermixed, these latter condensed into faint 
oblong spots on the third and fifth elytral interstices before and beyond the middle, the prothorax with 
an indistinct darker median vitta, the suture and alternate interstices of the elytra also set with rather 
stout, blunt, rigid sete, which become erect and conspicuous on the apical declivity ; the scales on the 
under surface in great part whitish. Head and rostrum together shorter than the prothorax, the head 
rather small, the rostrum transverse, moderately emarginate at the tip, hollowed, and canaliculate ; eyes 
not prominent. Prothorax about as long as broad, strongly constricted at the base, narrowed and 
feebly constricted in front, rounded at the sides, and somewhat produced at the apex, sparsely punctate ; 
vibrissee moderately long. Elytra a little wider than the prothorax, subparallel in their basal half, 
flattened on the dise anteriorly, abruptly declivous behind; coarsely punctate-striate, the interstices 
rather narrow, I (suture), 3, and 5 raised posteriorly. Anterior tibiz moderately long, bowed at the 
apex, unguiculate, and armed with about 7 small teeth. Intermediate and posterior tibie hollowed on 
the inner side near the tip. 
Length 4, breadth 13 millim. (¢.) 
Hab. Mexico, ‘‘ Sierra de Durango” (/Zége, ex Solar). 
One specimen. A small narrow form, with comparatively small head, a very short 
rostrum, and narrow, subparallel elytra, with erect, rigid, blunt sete on the alternate 
interstices. The head is much smaller than in P. ciliatipennis. 
35. Pandeleteius albisquamis, sp. n. (Tab. VIII. figg. 28, 28 a, ¢.) 
Moderately elongate, piceous, the prothorax usually with a darker median vitta, the legs (the anterior femora 
and claws excepted) and antenne (the club excepted) more or less ferruginous; densely, uniformly 
clothed with shining chalky-white scales, those on the under surface with a faint cupreous tinge. Head 
and rostrum together not longer than the prothorax, somewhat sparsely punctate, the rostrum flattened, 
emarginate at the tip, obsoletely canaliculate, the nasal plate triangular; eyes depressed. Prothorax 
broader than long, rather convex, feebly constricted at the sides before the apex, closely punctate ; 
vibrissee long, few in number. LElytra very little wider than the prothorax, subparallel in ¢, widened to 
beyond middle in @ and with the suture subangulate towards the apex (seen in profile) in this sex, 
the base slightly hollowed, the humeri obliquely truncate ; finely, conspicuously punctate-striate, the 
interstices almost flat. Anterior tibia moderately long, curved, denticulate, pilose, and sharply ungui- 
culate, the intermediate pair also with a minute claw in ¢. 
Length 43-6, breadth 12-2 millim. (¢ 9.) 
Hab. Mexico, San Andres Tuxtla (Sallé), Oaxaca (Hége); Guatemaua, Duefias 
(Salvin, Champion), San Geronimo (Champion). 
Found in abundance at Duenas. Lasily recognizable by the uniform dense white 
squamosity, which, however, does not hide the larger punctures on the upper surface, 
these being very conspicuous along the stri of the elytra. There are no short curled 
hairs amongst the scales. ‘The humeri are oblique, as in P. nodifer.
