258 RHYNCHOPHORA. 
5. Corthylus comatus, sp.n. (Tab. VIII. fig. 7, 9 , antenna.) 
Fem. Oblonga, subovata, picea, antennis pedibusque ferrugineo-testaceis ; fronte densissime flavo-villosa ; 
clava antennali intus pilosa; elytris posterius minus angustatis, apice obtusis, sat dense irregulariter 
punctatis, declivitate juxta suturam subimpressa, lineato-punctata, subglabra, haud tuberculata. 
Long. 3:1 millim. 
Female. Oblong, subovate, deep piceous. Forehead impressed and set with concentric rows of close, short, erect, 
shining, yellow hairs ; antennee ferruginous, the club oblique subreniform, the upper and apical margins 
obliquely and conjointly rounded, the lower margin subangulate, apparently triarticulate, the upper half 
of the inner face with close yellow hairs, scarcely produced beyond the apical angle, the outer face 
shortly pubescent. Prothorax as long as broad, the apex subelliptically rounded and bisinuate, the 
sides parallel behind the middle, the base truncate; disc with the postmedian elevated line short, 
its anterior half asperate, the asperities not very transverse, the posterior half scarcely visibly punctured. 
Scutellum not small, rounded triangular. Elytra one-third longer than the prothorax, the side- 
margins slightly rounded and narrowed behind, inflexed in a rounded angle to the obtusely-rounded 
apex; surface with rather strong close irregular punctuation; declivity convex, subimpressed, and with 
two rows of punctures on either side of the suture, gibbous towards the sides, not tuberculate, and with 
very few hairs. Underside piceous-black, the abdomen rufescent. Legs ferruginous. 
Hab. Guatemata, Cerro Zunil (Champion). 
One specimen. This species is distinguished from those most nearly resembling 
it by the dense villosity of the forehead and the inner face of the antennal club, which 
shows no sensitive patch. 
[To this division belongs C. redtenbacheri (Ferr.) and perhaps C. castaneus (Ferr.), 
both from Venezuela, of which a short account is given to supplement Ferrari’s 
descriptions. 
Corthylus castaneus. 
Pseudocorthylus castaneus, Ferr. Borkenk. p. 59, 9 (lege ¢) nec gL 
Male. Oblong, rather elongate, castaneous. Head infuscate, somewhat dull, moderately strongly punctured, 
the punctures obsolete towards the mouth, above which is a transverse impression ; antennal club rather 
broad-oval or subrhombiform, with two oblique sutures, the basal suture nearly straight, the other 
slightly curved. Prothorax as long as broad, semielliptic, obliquely narrowed forwards from behind the 
middle, base finely margined and subtruncate, lateral border very fine, deflexed ; surface with a transverse 
postmedian elevation, the anterior half with moderately transverse asperities, the posterior half subopaque, 
impunctate. Llytra two-thirds longer than the prothorax, scarcely narrowed at base, subampliated 
about the middle, scarcely narrowed behind, inflexed at apex, the apical margin very obtusely rounded 
and finely bordered; surface with moderately deep irregular punctuation ; declivity convex, thinly 
pilose, subimpressed on either side of the suture and lineato-punctate, the subelevated sutural margins 
and sides with a few small tubercles. 
Long. 3°7 millim. 
flab. Vexuzveia! (Mus. Vind. Ces.). 
This species somewhat closely resembles C. columbianus, Hopk., from the United 
States; the chief difference (apart from colour, which is of doubtful value) being in 
the antennal club, which is narrower in C. columbianus, with nearly straight sutures. 
I have not seen sufficient examples of the two forms to be able to decide whether they 
are really distinct. C. columbianus comes in the next division.
