EXOPHTHALMUS. 259 
greenish male from Teapa (fig. 17); a female, agreeing with the type of P. farino- 
lentus, from oxpam (fig. 18); a female of a greenish variety from Chiapas (fig. 19); 
and a female of the var. a from Santacomapan (fig. 20). 
14. Exophthalmus distigma, sp. n. (Tab. XI. fig. 21, ¢.) 
Oblong, black; densely clothed with cinereous scales, which are usually cupreous, purplish, or greenish in 
certain lights, and also set with small, scattered, adpressed setz, the vestiture sometimes more or less 
hidden or disguised by a yellowish exudation. Head and rostrum rugulosely punctate, the rostrum a 
little longer than broad and finely carinate to the rather long inter-ocular groove; eyes rounded, 
moderately large, feebly convex ; antenne rather long and slender, the scape about reaching the anterior 
margin of the prothorax, joint 2 of the funiculus slightly longer than 1. Prothorax transverse, obliquely 
narrowed from the middle forwards, feebly bisinuate at the base, broadly depressed or flattened, and 
sometimes obsoletely canaliculate, down the centre ; with a few, coarse, scattered punctures intermixed 
with a close fine punctuation. Scutellum prominent, rather large. Elytra subparallel in their basal 
half in ¢, broader and widened to the middle in @, feebly mucronate at the tip, the humeri rather 
prominent ; with rows of scattered punctures placed in small foves, the interstices densely punctulate, 
3 slightly raised to beyond the middle, and the space between it and the suture flattened or depressed, 
5 with a more or less distinct, transverse, bare, almost smooth, foveiform depression at about the basal 
third, and 4 sometimes with a similar depression beyond the middle, Anterior tibis strongly, and the 
intermediate tibie more feebly, unguiculate in both sexes. 
Length 77%,-124, breadth 24-5 millim. (¢ ¢ .) 
Hab. Guaremaua, Cerro Zunil, Volcan de Atitlan, and Mirandilla, Pacific slope 
(Champion). 
Found in abundance at Cerro Zunil in August 1880. ‘This is the Guatemalan form 
of the Mexican E. agrestis, from which it differs in having the elytra broadly flattened 
or hollowed along the suture (the depression extending forwards on to the disc of the 
prothorax), the seriate punctures more scattered, and the third interstice slightly raised. 
‘The upper surface usually has a cuprecus or greenish lustre. The bare depression on 
the fifth elytral interstice is constant. 
15. Exophthalmus scalptus, sp.n. (Lab. XI. fig. 22, ¢-) 
Oblong, narrow (¢), broader (Q ), black ; densely clothed (the head and rostrum more sparsely) with pearly- 
white scales (which sometimes have a cupreous or greenish tinge), the prothorax and elytra with small, 
scattered, bare—transverse, oblique, or foveiform—asymmetrically-arranged spots ; the surface also set 
with minute, widely scattered, adpressed, setiform scales. Head and rostrum rather sparsely punctate, 
the rostrum short, about as broad as long, hollowed on each side of the stout, arcuate median carina, 
the latter followed by a small inter-ocular fovea, the eyes large and somewhat depressed; antenne 
rather slender, the scape extending beyond the anterior margin of the prothorax. Prothorax transverse, 
convex, rounded at the sides, feebly bisinuate at the base; the spaces between the scattered, bare, 
irregular, foveiform depressions densely punctulate. Scutellum well developed. Elytra_ elongate- 
triangular in d, broader and widened to the middle in @, separately mucronate at the tip, the humeri 
not very prominent ; interruptedly seriate-punctate, the interstices (except in the places occupied by the 
bare transverse marks) densely punctulate, 3 usually a little raised and the space between it and the 
suture flattened or depressed. Anterior tibix feebly denticulate and with a long claw at the tip. 
Length 3-5, breadth 93-13 millim. (¢ Q.) _
