466 RHYNCHOPHORA. 
4. Tylodinus feedus, sp.n. (Tab. XXII. figg. 30, 30 a, 3.) 
Oblong-ovate, dull, black, the antenne ferruginous ; somewhat sparsely clothed with small dark brown scales 
and very short, erect, blunt sete, the legs with a few whitish sete intermixed. Head rugulosely punc- 
tate; rostrum rugosely punctate and unicarinate in its basal half, bare and sparsely punctured thence 
to the tip; antenne with joint 2 of the funiculus slightly longer than 1, 3-7 short, the club elongate. 
Prothorax broader than long, much narrowed in front, slightly hollowed at the base, somewhat flattened 
above; sparsely granulate and minutely punctate, the disc transversely depressed anteriorly, binodose at 
the middle, and with a very short median carina. Elytra somewhat pentagonal, slightly wider than the 
prothorax, bisinuate at the base; shallowly, interruptedly seriate-punctate and sparsely granulate ; each 
elytron with two very large, compressed, oblong, narrowly separated, lamelliform prominences on the 
outer part of the disc (the anterior one oblique), a conspicuous prominence at the shoulder, another below 
this projecting laterally, and two towards the suture. Femora feebly unidentate. 
Length 73, breadth 43 millim. (¢.) | 
Hab. Guatemata, Las Mercedes, Pacific slope (Champion). 
‘One specimen. In this insect the large lamelliform prominences on the elytra are 
placed further forwards than in 7. 4-lamellatus, and the humeri are each armed with 
a compressed tubercle, the elytra themselves being very little wider than the prothorax 
at the base. 
5, Tylodinus 16-tuberculatus, sp.n. (Tab. XXIL figg. 29, 294, 3.) 
Oblong-ovate, moderately shining, black, mottled with rufo-piceous ; sparsely clothed with intermixed brown 
and fulvous scales, the elytra also set with short, semierect, fuscous sete, the legs with fuscous and white 
sete. Head rugulosely punctate; rostrum rugulosely punctate and shallowly sulcate in its basal half, 
much smoother and bare thence to the tip, the antenne inserted at the middle, joints 1 and 2 of the 
funiculus subequal in length, 3-7 short, the club ovate. Prothorax nearly as long as broad, abruptly 
narrowed and tubulate in front, somewhat flattened on the disc, feebly hollowed at the base ; closely, very 
finely punctate, the more convex basal portion also granulate, the latter depressed down the middle. 
Elytra subpentagonal (as viewed from above), slightly wider than the prothorax at the base, the base 
itself bisinuate ; irregularly, interruptedly, seriate-punctate and conspicuously granulate, each elytron 
with eight large, rounded, granulate elevations on the disc, the posterior one on the third interstice the 
largest and the anterior one on the seventh projecting laterally. Femora unidentate. 
Length 73, breadth 4} millim. (¢.) 
Hab. Guaremaa, Quiché Mountains 9000 feet (Champion). 
One specimen. The subpentagonal, coarsely multituberculate elytra, the granulate, 
anteriorly tubulate prothorax, &c., distinguish this species. 
6. Tylodinus maculifrons, sp. n. (Tab. XXIII. fig. 1, @.) 
Oblong-ovate, moderately shining ; black, the antennez and the tips of the tarsi ferruginous 
with fulvous and dark brown scales, the fulvous scales on the prothorax condensed into 
elytra with a few white scales intermixed on the apical declivity, 
scales in front, the upper surface also thickly set with short, blunt, suberect, fuscous sete, the legs with 
fuscous and white setw. Head densely, rugulosely punctate 
; rostrum dilated towards the base, the basal 
portion rugulose, for the rest bare and almost smooth 3 antenne with joint 2 of the funiculus much longer 
than 1, 3-7 short, decreasing in length, the club ovate. Prothorax broader than long, abruptly narrowed 
anteriorly, the-base hollowed; closely, very finely punctate, the interspaces feebly granulate towards the 
sides, the dise transversely depressed before the middle and also depressed in the centre at the base.
