TYRANNION. 601 
18. Tyrannion unipustulatus, sp.n. (Tab. XXX. figg. 12, 12a.) 
Subovate, nigro-piceous, the antenne and the tip of the rostram more or less ferruginous; thickly clothed 
with small brown scales, the elytra usually with a few minute cinereous scales intermixed, the humeri 
or base fulvous, the prothorax with an oval or oblong, whitish or ochreous, spot in the middle behind ; 
the upper surface also set with short, suberect, fulvous and black setw, the latter clustered here and there 
into small, transverse or oblique, patches; the femora faintly annulate, cinereous at the base. Head 
rugulosely punctate, transversely depressed in front, the eyes very large and narrowly separated; rostrum 
strongly curved, nearly reaching the front of the metasternum, rugulosely punctate and carinate, the 
apical half finely punctate, smoother in the 2, the antenne inserted at (2) or beyond (¢) the middle, 
joints 1 and 2 of the funiculus subequal in length, the club ovate. Prothorax transverse, rounded at 
the sides, narrowed and constricted in front, deeply bisinuate at the base; densely, finely punctate. 
Scutellum oval. LElytra much wider than the prothorax, narrowing from a little below the base; with 
rows of oblong punctures placed in narrow, shallow strizw, the interstices becoming feebly convex towards 
the sides, 3 slightly raised near the base. Ventral segments 2-4 very sparsely punctate, 5 with a broad, 
depressed, pilose space in the centre at the apex, and also foveate at the tip,in the ¢. Legs rather short ; 
femora unidentate. 
Length 33-6, breadth 2-2,9, millim. (¢ 9.) 
Hab. Gvuatema.a, San Juan in Vera Paz (Champion); Nicaragua, Chontales (Janson) ; 
Panama, Bugaba, Volcan de Chiriqui (Champion). 
Eleven specimens, all but two from Chiriqui, the one from Guatemala larger than 
the others, more coarsely setose, and with a larger spot at the base of the prothorax. 
T. unipustulatus bears a superficial resemblance to Hubulus reticulatus. 
19. Tyrannion curtipennis, sp.n. (Tab. XXIX. fig. 19.) 
Broad ovate, short, black or piceous, the antenne, the sides of the rostrum, and the tips of the tarsi ferruginous ; 
somewhat thickly clothed with small brown scales, with ochreous and blackish scales intermixed, the 
ochreous scales sometimes condensed into a few indistinct spots on the elytra, the elytra also sparsely set 
with suberect setiform scales. Head rugosely punctate, flattened above the widely separated eyes ; 
rostrum strongly curved, reaching to the middle of the intermediate cox, rugosely punctate and carinate 
at the base, and very finely punctate thence to the apex, the antenne inserted slightly beyond the middle. 
Prothorax transverse, rounded at the sides, much narrowed and feebly constricted in front, deeply 
bisinuate at the base; densely, finely punctate, and obsoletely carinate. Scutellum small. Elytra 
short, broad, much wider than the prothorax, widening to near the middle and rapidly narrowing thence 
to the apex, the humeri obtuse ; seriate-punctate, the interstices subseriato-granulate, the outer ones a 
little raised, 3 slightly swollen and setose near the base. Beneath sparsely punctate. Mesosternum 
horseshoe-shaped. Legs short; femora unidentate. 
Length 44-4,%,, breadth 22-24 millim. (¢ ?) 
Hab. Guatemata, Cerro Zunil (Champion). 
Four specimens, one somewhat immature and with the base of the elytra reddish. 
The short, broad, posteriorly widened form separates 7. curtipennis from the allied. 
species. The elytral vestiture is somewhat variable in colour, the blackish scales being 
sometimes numerous on the apical declivity; the interstices are distinctly seriato- 
granulate, the first (sutural) excepted. 
20. Tyrannion albosignatus, sp.n. (Tab. XXIX. fig. 20.) 
Ovate, rather broad, nigro-piceous, the antenne and the tip of the rostrum ferruginous ; somewhat thickly 
clothed with brownish or fulvous scales, with blackish scales intermixed, the elytra with a sharply-defined
