as the prothorax, very minutely seriate-punctate, the interstices quite flat and each with an excessively 
minute row of punctures. Legs slender. 
Length 14 millim. 
Hab. British Honpuras, Belize (Blancaneauz). 
One specimen. Not unlike P. pallidus, Fahr., from St. Vincent, W.I., but with 
the punctuation of the upper surface much less distinct, the prothorax narrower, and the 
legs more slender. 
13. Phyllotrox depressus, sp. n. 
Oblong-ovate, somewhat depressed, shining, glabrous; piceous, the prothorax rufo-testaceous at the hase, the 
scape and funiculus of the antenne, the legs, the apex of the abdomen, and the elytra testaceous, 
the suture of the latter faintly infuscate in front. Rostrum fully as long as the prothorax, closely, 
finely punctate. Prothorax transverse, somewhat rounded at the sides, a little more narrowed in front 
than at the base, closely, finely punctate. Elytra slightly wider than the prothorax, oblong; the 
surface punctured like that of the prothorax, the obliterated strie, however, showing through from 
beneath. Legs stout, the four hinder tibiz acutely produced at the outer apical angle. Pygidium 
visible, unimpressed. 
Length 27 millim. (<d.) 
Hab. GuateMata, Cerro Zunil (Champion). 
One specimen, perhaps abraded. More depressed than any of the other Central- 
American forms, and with the elytra confusedly punctured, the strie, however, showing 
through from beneath. This insect has much the facies of a Derelomus. 
TERIOLTES, gen. nov. 
Rostrum elongate, slender, the scrobes rapidly descending and reaching the lower anterior margin of the 
eyes ; eyes rounded, prominent, somewhat widely separated ; antennee elongate, inserted at about one- 
third from the apex of the rostrum, the funiculus 7-jointed—joint 1 obconic, stout, much longer than 
broad, 2 smaller and shorter, 3-7 transverse, becoming very gradually wider, 7 much narrower than the 
club,—the latter ovate and acuminate, with the sutures not very distinct; head very little produced 
behind the eyes; prothorax convex; scutellum very small; elytra ovate, covering the pygidium ; 
anterior coxe contiguous; prosternum moderately long (2. cirewmdatus) or very short (Z'. nigripennis) ; 
ventral segments 1 and 2 connate, 3 and 4 very short, the sutures straight; femora more or less 
thickened, unarmed ; tibie narrow, straight, simply truncate and unarmed at the apex; tarsi rather 
slender, sparsely villose beneath, the third joint bilobed, the claws simple, divergent ; body oblong-ovate, 
very sparsely pubescent. 
The two small species referred to this genus are very closely related to Phyllotrox, 
but they cannot be included in it on account of the structure of the antenne, the 
funiculus being relatively longer and the outer joints much narrower than the club. 
The only other nearly allied American genus known to me is Ophthalmoborus 
(Anthobius olim), which has the head more prolonged behind the eyes, the antenne 
inserted at the middle of the rostrum, and the funiculus formed as in Phyllotroz. 
Xanthus, Dietz, is perhaps an allied form, but it is described as having a freely 
exposed pygidium, the antennal club loosely articulate, &c.
