146 RHYNCHOPHORA. 
variegate, forming two or three vague, slightly darker, transverse fascize, but sometimes 
they are nearly or quite unicolorous; there are regular series of deep punctures—these, 
when the scales are intact, appear rather small, but when the scales are removed they 
are seen to be large and each to be separated from the one behind it by only a slender, 
transverse interstice. Legs squamose, the teeth on all the femora acute. 
A good series was obtained of this species, all from the Atlantic slope, those from 
Guatemala coming from the Polochic valley. 
2. Bufomicrus globipennis, sp. n. 
Dense griseo-squamosus, subviridescens ; prothorace elongato ; femora omnia dentata. 
Long. 6 millim. 
Hab. GuateMaua, Yzabal (Saillé). 
This species is closely allied to B. sguamosus, but can be recognized by the more 
elongate thorax, the more convex eyes, and by the sete on the elytra being depressed 
and differing very little from the scales, so that at first sight they escape detection ; the 
rostrum is flat in front, without depression or fovea. 
I have seen only two examples of B. globipennis; they differ a little from one 
another in colour, and this character is probably of but little importance. 
8. Bufomicrus cristatus, sp.n. (Tab. VI. fig. 11.) 
Dense fusco-squamosus, parce hispidus, elytris cristis brevibus ornatis; femora intermedia et posteriora 
mutica. 
Long. 6 millim. 
Hab. Guatemata, Sinanja (Champion). 
Scape of antenne sinuous, slender and glabrous at the base, much thicker and 
clothed at the apex. Eyes rather convex, a fovea between them. Thorax elongate, 
rounded at the sides and narrowed in front, the surface apparently coarsely sculptured, 
but completely covered with squamosity. Elytra covered with dark squamosity, which 
is very obscurely variegate, bearing erect clavate sete, and with several short, slight, 
cristiform elevations. ‘Tibi rather slender, hispid. The front femora with a large 
angular dilatation beneath. 
Only one specimen was procured of this remarkable species; it differs from its 
congeners not only in the unarmed posterior femora, but also in the fact that the nasal 
plate is surrounded by a curvate, glabrous, explanate space or margin; the scrobes, too, 
are broader. 
MASEORHYNCHUS, gen. nov.
