596 RHYNCHOPHORA. 
triangular, the humeri swollen, obtuse; seriate-punctate, the interstices punctulate, 9 narrowly costate, 
the others flat. Beneath coarsely, rugosely punctate. Mesosternum long, horseshoe-shaped. Legs 
rather short ; femora feebly clavate, each with a long tooth; tibiz sinuous within, rounded at the base 
externally. 
Length 5, breadth 3 millim. (2 ?) 
Hab. Nicaragua, Chontales (Belt). 
One specimen. <A species of ovate, convex form, with a sharply-defined, broad, 
curved black streak at the base of each elytron (the two markings together forming an 
interrupted saddle-shaped patch), the rostrum long and strongly curved, the ventral 
segments and metasternum very coarsely, rugosely punctate. 
6. Tyrannion irregularis, sp.n. (Tab. XXIX. figg. 13, 13 a.) 
Broad ovate, black, the elytra variegated with piceous, the antenne obscure ferruginous; the head, elytra, 
and legs thickly clothed with cinereous scales, with fulvous scales intermixed, the fulvous scales clustered 
into large indeterminate patches on the elytra, the latter with an irregular series of black spots along the 
suture and a small triangular black patch at the sides near the apex; the prothorax clothed with short 
erect black scales, and with a curved fulvo-cinereous stripe on each side of the disc; the elytra also 
thickly set with rather coarse suberect sete; the vestiture of the under surface very sparse. Head 
rugulosely punctate, arcuately depressed in front, the eyes distant ; rostrum stout, strongly and abruptly 
curved, cylindrical, reaching to the middle of the intermediate coxe, rugose, carinate and depressed at 
the base, and closely, finely punctate thence to the apex, except along the smooth median space, the 
antennee inserted midway.. Prothorax short, much narrowed in front, the sides arcuately converging 
from the base; densely punctate. Scutellum small, oblong. Elytra much wider than the prothorax, 
moderately convex, rounded-triangular, the humeri obtuse ; seriate-punctate, the interstices punctulate, 
almost flat, 9 narrowly costate posteriorly. Beneath coarsely and closely, the ventral segments 2-4 more 
sparsely, punctate. Mesosternum horseshoe-shaped. Legs stout; femora sharply unidentate; tibie 
rounded at the base externally. 
Length 64, breadth 33 millim. (¢.) 
Hab. Panama, Volcan de Chiriqui (Champion). 
One specimen. A broad, ovate form, with the elytra densely and the prothorax 
sparsely squamose; the elytra with a series of irregular black spots along the suture 
(much as in Cryptorhynchus illex, Germ.) and the disc clouded with fulvous. 
7. Tyrannion suffusus, sp.n. (Tab. XXIX. fig. 14.) 
Broad ovate, robust, black, the antenne ferruginous ; somewhat thickly clothed with reddish-brown scales, 
the elytra with a broad space before the middle indeterminately cinereous, and some irregular markings 
on the apical half of the sutural region, and the apex itself, black; the upper surface also set with 
scattered, coarse, suberect, fulvous and black, setiform scales, the black scales condensed into a small 
fascicle below the base of the third elytral interstice. Head rugosely punctate, the eyes somewhat 
narrowly separated ; rostrum strongly curved, nearly reaching the metasternum, rugosely punctate and 
subcarinate at the base, the apical half almost smooth, the antenne inserted at about the middle. 
Prothorax transverse, somewhat dilated at the sides, rapidly narrowed from the middle and constricted 
in front; densely punctate. Scutellum small, oval. Elytra about one-half wider than the prothorax, 
rapidly narrowing from a little below the base, transversely depressed before the middle, the humeri 
obtuse and rather prominent ; seriate-punctate, the interstices punctulate, flat or feebly convex, 9 sub- 
costate. Beneath closely, coarsely punctate. Legs rather short and stout; femora sharply unidentate. 
Length 7-75, breadth 4 millim. 
Hab. Panama, Volcan de Chiriqui (Champion).
