tufts. Elytra elongate and narrow, with series of punctures made obscure by the 
clothing, fuscous, with vague white markings, the apical margins expanded by means 
of protruding pallid scales; the male just above the apex with two long squamose 
protuberances, the female with two small tubercles instead. Under surface and legs 
more pallid than the upper surface, nearly white; rostrum, however, as dark beneath 
as above. 
Three specimens. 
Allied to U. pannosus, Boh., but smaller, with the head shorter and less lobed 
behind. 
2. Ulocerus sordidus, sp. n. 
Angustus, squalide fusco-squamosus; antennis latiusculis, haud difformibus. 
Long. 9 millim. 
Hab. Panama, Bugaba (Champion). 
A very narrow insect, of which we have received only one male example. ‘The head 
is short and rather broad, the eyes small and but little prominent. The antenne are 
covered with very coarse, seta-like scales arranged in whorls and subdepressed ; joints 1-6 
are rather dark fuscous; the seventh and eighth joints are more pallid; the ninth is 
small, acuminate, dark, but not black, its clothing fine, not coarse like that of the 
preceding joints. Thorax long and narrow, very densely squamose, its surface a little 
uneven. Elytra very narrow, like the thorax extremely densely squamose ; the sculp- 
ture (which is probably coarse and deep) concealed by the clothing; each apical angle 
squamose, the tubercle above the apex indistinct. 
3. Ulocerus mexicanus, sp. n. 
Angustus, pallide fusco-squamosus, in elytris squamis erectis nigro-fuscis vestitus ; antennis fere gracilibus. 
Long. 8 millim. 
Hab. Mexico, Playa Vicente, Cordova (Sallé). 
This insect is very closely allied to U. sordidus, but the head is of a different shape, 
being longer and narrower, with the eyes more exposed from above; the antenne are 
not so broad, and the erect squamosity on the elytra is more distinct. The form of the 
elytral apices is much the same as in U. sordidus, there being only a small tuft above 
the prominent apical angles; the two sexes are similar in this respect. ‘The antenne 
have the basal joint rather long ; the rostrum, head, and thorax are sulcate along the 
middle, the back of the head exhibits very little lobing of the angles. The lower 
surface is paler than the upper; the legs are slender.
