600 RHYNCHOPHORA. 
finely punctate thence to the apex, smoother in the 2, the antennex inserted beyond the middle in both 
sexes. Prothorax transverse, rounded at the sides anteriorly, feebly constricted and much narrowed in 
front; densely punctate, and sometimes obsoletely carinate. Scutellum small. Elytra much wider 
than the prothorax, narrowing from a little below the base; shining, seriate-punctate, the interstices 
punctulate and feebly convex, 9 narrowly costate. Beneath rather sparsely punctate ; terminal dorsal 
segment of the abdomen tridentate at the apex in the 2. Femora moderately clavate, unidentate. 
Length 33-44, breadth 13-21 millim. (¢ 2.) 
Hab. Panama, Volcan de Chiriqui (Champion). 
Six specimens; a seventh from Sinanja, Vera Paz, with rather darker scales and 
shorter sete may also belong here. Smaller and narrower than 7. imbellis, the 
antenne inserted beyond the middle of the rostrum in both sexes, the rostrum very 
slightly widened towards the base, the vestiture ochreous and black intermixed, the 
hidden terminal dorsal segment of the abdomen of the female tridentate (instead of 
simply truncate) at the apex, the femoral tooth less acute. 
16. Tyrannion stolidus, sp. n. 
Very like 7. admixtus, but with the vestiture brown, cinereous, and black intermixed, the cinereous scales 
somewhat fasciculate on the elytra, the setiform scales short, the black ones clustered into a small 
fascicle near the base of the third elytral interstice; the antenne inserted a little further from the tip 
of the rostrum, the latter less elongate in the 9, carinate at the base, reaching to the middle of the 
intermediate coxe; the ventral segments closely punctate. 
Length 4-43, breadth 2-23 millim. (¢ 2.) 
Hab. Guatemata, San Juan in Vera Paz (Champion). 
Three specimens, apparently including both sexes, the male partly abraded. 
17. Tyrannion squalidus, sp. n. 
Subovate, nigro-piceous, the antenne: and tarsi more or less ferruginous; somewhat thickly clothed with 
brown scales, the elytra mottled with blackish in one specimen, the upper surface also set with short, 
semierect, pallid, and blackish, setiform scales. Head rugulosely punctate, the eyes distant ; rostrum 
curved, subcylindrical, reaching to the middle of the intermediate coxe, rugosely punctate and carinate 
at the base, and sparsely, minutely punctate thence to the tip, the antenne inserted midway. Prothorax 
transverse, rounded at the sides, constricted and much narrowed in front; densely punctate. Elytra 
a little wider than the prothorax, narrowing from near the base, the humeri rounded; seriate- 
punctate, the interstices feebly convex, rugulose, and subgranulate. Beneath sparsely punctate. 
Mesosternum U-shaped. Legs short; femora clavate (the anterior pair somewhat strongly), sharply 
unidentate. 
Length 45-43, breadth 2-21 millim. ( 9.) 
Hab. Mexico, Jalapa (Hége), Teapa (H. H. Smith). 
Two specimens, the one from Teapa with the elytral vestiture mottled with black, 
the other with the scales of a uniform brownish colour. Near 7" stolédus, but with 
the elytra relatively narrower, the anterior femora more clavate.’ The less widely 
separated, partly exposed eyes, &c., separate 7. sgualidus from all the species here 
referred to Metriophilus.
