PSEUDOMOPSIS. 489 
apical declivity, at about one-third from the apex. Head densely punctate, the eyes moderately distant ; 
rostrum rugulosely punctate and faintly carinate, with the apex sparsely punctate, the apical half smoother 
in the 9. Prothorax transverse, subconical, feebly constricted in front, densely punctate. Scutellum 
minute. Elytra convex, very much wider than the prothorax, subtriangular, almost parallel at the base, 
the humeri rounded and not prominent ; seriate-punctate, striate towards the suture, the interstices almost 
flat and minutely punctulate. Femora unarmed. 
Length 31,-32, breadth 14-2 millim. (¢ 9.) 
Hab. Panama, Volcan de Chiriqui 4000 feet (Champion). 
Five specimens. In this insect the elytra are set with numerous broad, semierect 
scales along the second and fourth interstices to as far as the transverse subapical 
fascia, where they are clustered into fascicles. The white spots or streaks on the 
anterior part form an interrupted irregular fascia. ‘The dark scales on the prothorax 
show a tendency to form two or three interrupted transverse bands. 
7. Pseudomopsis notaticollis, sp.n. (Tab. XXIV. fig. 2.) 
Rhomboidal, shining, black, more or less mottled with ferruginous, the antenne and tarsi also of that colour ; 
densely clothed with brownish-white or pale ochreous scales, the vestiture sparser and in part blackish 
on the middle of the prothorax (the dark scales clustered into two oblong patches on the disc) and on a 
common transverse space on the disc of the elytra at the base, the elytra each with an oblique brownish 
streak below this, their alternate interstices set’ with a few widely scattered, coarse, semierect scales ; 
the vestiture of the legs and under surface whitish and ochreous intermixed, Head densely punctate, 
the eyes large and rather narrowly separated ; rostrum thickly punctate, rugulose at the base, smoother 
towards the apex in the 2; joints 1 and 2 of the funiculus subequal in length. Prothorax transverse, 
conical, densely punctate, except along the smooth median line. Scutellum minute. Elytra convex, 
much wider than the prothorax, subtriangular, parallel at the base, the humeri rounded and not promi- 
nent ; punctate-striate, the interstices flat. Femora unarmed. 
Length 3-34, breadth 13-1§ millim. (¢ @.) 
Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion). 
Three specimens. Near P. mexicanus, Chevr., but with the elytra relatively broader 
at the base and the raised setiform scales larger and confined to the alternate 
interstices, the prothorax more constricted in front and with the scales differently 
coloured, &c. The vestiture of the head and elytra (except at the base) is so dense 
as to hide the whole of the sculpture. 
8. Pseudomopsis mexicanus. 
Pseudomus mexicanus, Chevr. Le Nat. ii. p. 279 (Sept. 1880) ’. 
Subrhomboidal, narrow, rather elongate, shining, piceous, the antenne and the tips of the tarsi ferruginous ; 
densely clothed with intermixed ochreous and whitish scales, the latter sometimes condensed into small 
spots on the prothorax and two indistinct oblique fascie on each elytron, the space between the fasciz 
often more sparsely squamose and with some blackish scales intermixed, the dorsal interstices each with 
a row of small slightly raised scales, Head densely punctate, the eyes rather narrowly separated ; rostrum 
rugulose and squamose at the base, thickly punctate at the tip, smoother in the 9. Prothorax slightly 
broader than long, narrowing from the base ; densely punctate, and sometimes feebly carinate. Scutellum 
minute. Elytra convex, slightly dilated below the base and rapidly narrowing thence to the apex, the 
humeri rounded; shallowly seriate-punctate, the interstices almost flat. Femora unarmed. 
Length 3-34, breadth 12-1} millim. (3 Q .)
