EXOPHTHALMUS. 265 
anteriorly, hollowed down the middle and towards the sides, the median sulcus faintly canaliculate 
towards the apex, the base feebly bisinuate; foveato-punctate and transversely wrinkled. Elytra broad, 
gradually widened to the middle, acuminate and mucronate at the tip, the humeri not very prominent ; 
with rows of rather fine scattered punctures which are each placed in a large fovew, the fovea themselves 
here and there transversely confluent, the interstices uneven throughout, 
Length 131-153, breadth 44-52 millim. 
Hab. Guatemaua, Cerro Zunil 4000 fect, Pacific slope (Champion). 
Five specimens, probably all females. The prothorax and elytra in this insect have 
alternate pale blue and golden-green stripes, and the surface very uneven. ‘The 
following is an allied form from the Atlantic slope of the same country. 
27. Exophthalmus bilineatus, sp.n. (Tab. XII. fig. 5, 2.) 
. Oblong, black ; densely clothed with golden-green and flesh-coloured (or pale cupreous) scales, the latter 
predominating on the head and rostrum, and condensed into two vittz on the dise of the prothorax, a 
spot at each angle of the latter, and two stripes on each elytron (one, sinuous, running down the middle 
of the disc to near the apex, the other along the lower margin), the legs green with golden and cupreous 
tints, the minute scales between the bristles on the antenne (except on the brown club) pale cupreous : 
the surface also set with very short, fine, adpressed, scattered hairs. Head and rostrum rugulosely 
punctate, the rostrum finely carinate, the carina followed by a short inter-ocular groove; eyes large, 
rounded, moderately prominent. Prothorax a little broader than long, narrowed anteriorly, depressed 
down the middle; confluently foveato-punctate. Elytra broad, parallel in their basal third, acuminate 
and mucronate at the tip, the humeri rather prominent; closely seriato-foveate, the rows 3-5 (covered by 
the carneous sinuous stripe) irregular or interrupted before the middle, the third interstice distinctly 
raised, the space between it and the suture flattened anteriorly. 
Length 143, breadth 54 millim. 
Hab. GuateMata, Purula in Vera Paz (Champion). 
One specimen in very fresh condition. Very near FE. ceruleovittatus (9), but with 
the elytra parallel at the base, and each ornamented with a sinuous flesh-coloured 
stripe, which is limited inwards by the slightly raised third interstice, the prothorax 
with two similarly coloured vittz on the disc; the fovee (in which the small seriate 
punctures of the elytra are placed) large, the rows 3-5 interrupted or irregular. 
28. Exophthalmus sulcipennis, sp. n. (Tab. XII. fig. 6, 2.) 
>. Elongate, subcuneiform, shining, black; above sparsely, the legs and under surface densely, clothed with 
scintillating metallic-green scales, those on the prothorax condensed into a narrow vitta on each side of 
the disc and those on the elytra into a stripe down each alternate interstice. Rostrum longer than broad, 
with a rather broad, smooth, raised median line, which is continued narrowly backwards beyond the 
inter-ocular fovea; antennal scape reaching the posterior margin of the eyes, the latter rounded and 
prominent, Prothorax about as long as broad, subquadrate, slightly narrowed in front, feebly bisinuate 
at the base, and hollowed down the middle; irregularly, confluently foveolate and finely punctate. 
Scutellum rounded. Elytra elongate, widened to the middle, transversely depressed at the base, 
acuminate and sharply mucronate at the apex, the humeri not very prominent; with twelve rows of 
coarse punctures, the interstices transversely confluent, 3, 5, 7, and 9 raised, the others almost flat and 
squamose. Tibi without denticles, the anterior pair strongly unguiculate. 
Length 17, breadth 54 millim.
