150 RHYNCHOPHORA. 
9. Auleutes biolleyi, sp.n. (Tab. 1X. fig. 3, 2.) 
Short ovate, black, the antenne, apical margin of the elytra, knees, and tarsi ferruginous; variegated above 
with a somewhat dense clothing of small cinereous (or pale ochreous) and brown scales, the dorsal 
elevations of the prothorax and the base of the suture blackish. Head finely, rugulosely punctate, 
slightly depressed between the eyes; rostrum arcuate, comparatively slender, longer than the prothorax, 
rugulose and dull in the g¢,a little more elongate, shining, and almost smooth in the 9. Prothorax 
narrowing from near the base, densely, finely punctate, the disc sulcate and binodose, the lateral 
tubercles prominent, the anterior margin notched in the middle and armed with two small compressed 
tubercles, Elytra broad, finely punctate-striate, the interstices rugulose, the alternate ones rather 
convex, the sutural region depressed anteriorly. Mesosternal excavation almost obsolete, limited on 
each side by a distinct ridge. Fifth ventral segment shallowly foveate, and the intermediate tibie 
unguiculate at the inner apical angle, in the g. 
Length 2, breadth 14 millim. (¢ @.) 
Hab. Costa Rica, San José (Biolley). 
One pair. This species has wholly the facies of a Phytobiid, but as the mesosternal 
depression is traceable, and the funiculus is 7-jointed, it must be placed in Auleutes. 
The rostrum is almost smooth in the female, and rugose in the male, as in A. znspersus. 
10. Auleutes dispersus, sp. n. 
Short ovate, black, the antennz, anterior margin of the prothorax, apical margin of the elytra, knees, and 
tarsi ferruginous; the vestiture very fine, cinereous intermixed with brown, the cinereous scales on the 
elytra not clustered into definite spots, the under surface with scattered whitish scales. Head rugulosely 
punctate, carinate on the vertex; rostrum very stout, arcuate, rather longer than the prothorax, rugosely 
punctate. Prothorax densely, finely punctate, the disc shallowly suleate, not or obsoletely binodose, the 
lateral tubercles prominent, the antcrior margin notched in the middle. Elytra punctate-striate, the 
interstices rugulose and feebly convex. Mesosternum somewhat deeply excavate, the metasternum also 
slightly depressed between the middle coxe. Fifth ventral segment feebly foveate in the ¢. Legs 
rather slender ; intermediate and posterior tibixe sharply unguiculate at the inner apical angle in the ¢. 
Length 2-21, breadth 13-13 millim. (¢ 9.) 
Hab. Mexico (Truqut, in coll. Fry), Xucumanatlan and Amula (H. H. Smith). 
Three specimens. Closely related to A. mexicanus and A. similis, the prothorax 
finely punctate and without definite tubercles on the middle of the disc, the vestiture 
very fine, not clustered into definite markings on the elytra. 
11. Auleutes inermis, sp. n. 
Short ovate, black, the antenne, the extreme base of the femora, knees, and tarsi (the apical joint excepted) 
ferruginous ; the vestiture very fine, fuscous above, with scattered coarser white scales intermixed, these 
latter condensed into a narrow longitudinal line on each side of the disc of the prothorax, which extends 
outwards along the basal margin, and various faint spots and streaks on the elytra (a short streak on the 
second interstice below the base and a transverse mark at the middle of the sides conspicuous), the under 
surface also with white scales. Head rugulosely punctate, the eyes separated by rather less than the 
width of the rostrum; the latter stout, feebly arcuate, a little longer than the prothorax, rugulosely 
punctate and finely carinate. Prothorax constricted in front, narrowing from near the base; densely, 
very finely punctate, the anterior margin notched in the centre, the dorsal and lateral tubercles wanting. 
Elytra subcordate, deeply punctate-striate, the interstices rugulose and somewhat convex. Mesosternal 
excavation very shallow. Legs comparatively slender ; intermediate and posterior tibixw feebly ungui- 
culate at the inner apical angle. 
Length 1%, breadth 1,4, millim. (<¢.)
