TYRANNION. 5995 
metasternum, rugosely punctate and subcarinate at the base, the apical half very finely punctate, the 
antenne inserted beyond the middle. Prothorax transverse, rounded at the sides, constricted and much 
narrowed in front; closely punctate, the narrow interspaces alutacecus, the disc feebly binodose. Elytra 
much wider than the prothorax, narrowing from near the base, the humeri obtuse; seriate-punctate, 
the interstices punctulate and feebly convex. Beneath rather sparsely punctate. Mesosternum U-shaped, 
the walls hollowed. Femora unidentate. 
Length 5, breadth 22 millim. 
Hab. Panama, Volcan de Chiriqui (Champion). 
One specimen, apparently with the vestiture of the prothorax partly abraded, 
though the fascicles of blackish setee on the middle of the disc are conspicuous. 
The clothing of the elytra is almost entirely fulvous. This insect superficially 
resembles Hubulus atricollis. 
4. Tyrannion scabidus, sp.n. (Tab. XXIX. figg. 10, 10a.) 
Subovate, black, the antennz and the tips of the tarsi ferruginous ; somewhat thickly clothed with fulvous scales, 
which are clustered into four small fascicles across the middle of the prothorax and numerous fascicles 
on the elytra (becoming more conspicuous on the elevated portions of the surface), the elytra also with a 
short, transverse, curved, black streak near the suture at about the middle, the setiform scales decumbent 
and inconspicuous ; the vestiture of the under surface sparse and pale. that of the lege close, fulvous and 
cinereous intermixed, Head rugosely punctate, carinate between the eyes, which are large and narrowly 
separated ; rostrum strongly curved, rather slender, somewhat tapering, reaching the front of the meta- 
sternum, carinate, shallowly sulcate, and rugulosely punctate at the base, almost smooth in its outer half, 
the antenne inserted at about the middle. Prothorax transverse, rounded at the sides, constricted and 
much narrowed in front; densely, finely punctate and obsoletely carinate. Scutellum oblong. Elytra 
fully one-half wider than the prothorax, narrowing from a little below the base, flattened on the disc 
anteriorly, the humeri somewhat swollen ; seriate-punctate, the interstices punctulate, faintly granulate, 
here and there nodose, 3 with a more distinct prominence below the base and another at the middle. 
Ventral segments sparsely, coarsely punctate. Mesosternal cavity long, parallel-sided. Legs moderately 
long ; femora feebly clavate and sharply unidentate ; tibize and tarsi rather slender. 
Length 6-63, breadth 3-3} millim. (@.) 
Hab. Panama, Volcan de Chiriqui (Champion). 
Two specimens. Narrower than 7’ tricristatus, the prothorax wanting the dorsal 
hump, &c., the elytra more nodose, with less prominent humeri, the black spot near 
the suture transverse, curved. 
5. Tyrannion nigrosellatus, sp.n. (Tab. XXIX. fig. 12.) 
Ovate, convex, black, the antenne and the tips of the tarsi ferruginous ; somewhat thickly clothed with 
small reddish-brown scales, with a few cinereous or whitish scales intermixed (especially on the front of 
the humeri, along the suture and flanks of the elytra, and on the legs), the elytra also set with scattered, 
coarser, decumbent, setiform scales and each with a short, broad, curved black streak at the base (arising 
from near the scutellum and obliquely truncated behind); the vestiture of the under surface coarse and 
pale. Head rugulosely punctate, arcuately depressed in front, the eyes rather narrowly separated ; rostrum 
strongly curved, reaching the front of the metasternum, rugosely punctate, subcarinate, and a little 
widened at the base, the apical half almost smooth, the antenne inserted at the middle. Prothorax 
strongly transverse, feebly constricted in front, the sides rapidly, arcuately converging from the base, the 
latter deeply bisinuate; closely, finely punctate and obsoletely carinate, the disc transversely swollen 
at the middle. Scutellum oval. Elytra rather short, convex, much wider than the prothorax, rounded-
