TYRANNION. 597 
Three specimens, probably including both sexes. Broader than 7. nigrosellatus, 
the eyes more approximate, the rostrum longer and not so stout, the head more 
rugose, the prothorax more dilated at the sides, the elytra differently marked and with 
more prominent humeri, &c. 
8. Tyrannion diffusus, sp. n. 
Broad ovate, nigro-piceous or black,.the antennz and the tips of the tarsi ferruginous; somewhat thickly 
clothed with brown scales, with a few lighter and darker scales intermixed, the latter clustered 
into small scattered spots on the basal half of the elytra, the elytra also with a series of semierect 
coarser scales along each interstice and a small fascicle of dark sete near the base of the third; the 
vestiture of the under surface sparse. Head rugosely punctate, flattened above the eyes, the latter rather 
widely separated ; rostrum strongly curved, reaching to the middle of the intermediate coxe, coarsely, 
rugosely punctate at the base, and for the rest sparsely, very finely punctate, the antenne inserted 
at about the middle. Prothorax transverse, rounded at the sides, much narrowed and feebly constricted 
in front; densely, finely punctate, and sometimes feebly carinate. Scutellum oblong. LElytra about 
one-half wider than the prothorax, arcuately narrowing from a little below the base, the humeri rather 
prominent, obtuse ; seriate-punctate, the interstices punctulate and sparsely granulate, 3 slightly swollen 
below the base. Beneath shining, sparsely punctate. Mesosternum U-shaped. Femora feebly clavate. 
_ sharply unidentate. 
Length 53-64, breadth 3-34 millim. 
Hab. Guatema.a, Senahu and San Juan in Vera Paz, Atlantic slope (Champion). 
Five specimens (one now without a head), probably including both sexes. More 
convex than 7’. suffusus, the vestiture not so coarse and more uniformly coloured (the 
elytra not suffused with cinereous before the middle, nor with a blackish apical 
patch), the eyes less approximate, the elytral interstices each with a conspicuous series 
of raised scales, the legs not so stout. Metriophilus discretus, Faust, from Venezuela, 
is not unlike the present species; but it has a less transverse prothorax, with more 
prominent ocular lobes, a smaller scutellum, obtuse humeri, &c. 
9, Tyrannion pictilis, sp.n. (Tab. XXIX. fig. 15.) 
General characters as in 7’. diffusus; the vestiture of the upper surface brown, the elytra with small, 
scattered, irregularly distributed, whitish spots, including one at the apex of the fifth interstice, the third 
with a small cluster of dark setiform scales below the base, the other raised scales inconspicuous; the 
rostrum rugosely punctate and carinate at the base ; the prothorax less dilated at the sides; the elytra 
broadly flattened on the disc anteriorly. 
Length 54-6,,, breadth 3-3} millim. 
Hab. Mexico, Toxpam in Vera Cruz (Sallé). 
Three specimens. This is the Mexican representative of the Guatemalan 7. digfusus, 
and requires a separate name. The elytra are more depressed and shorter than in 
T. ochreopunctatus, and the spots are paler and less sharply defined. 
10. Tyrannion disparilis, sp.n. (Tab. XXIX. fig. 16.) 
Closely related to 7’. diffusus, but with the elytra relatively longer, the vestiture brown, mottled with 
cinereous and black, the cinereous scales condensed into two interrupted, transverse, sinuous fascie
