types, the long series from the three localities in Guerrero belonging to the immaculate 
form. Coleocerus setosus varies in the same way in the colour of the scales. 
2. Eucoleocerus guttularius, sp.n. (Tab. XIV. figg. 19,194, ¢.) 
3. Oblong, subfusiform, convex, black, the tibiz, tarsi, and base of the antennzx ferruginous in one example; 
variegated with a dense clothing of whitish and fuscous scales, the dark scales on the prothorax wholly 
condensed into two broad narrowly divided vittee on the disc, and those on the elytra asymmetrically 
confluent, the scales on the scutellum, legs, and under surface whitish, with a faint cupreous tint, the 
ventral segments with intermixed decumbent white hairs; the upper surface also set with very short, 
curled, fine, semierect setae. Rostrum and antenne asin £. conicicollis. Prothorax transverse, gradually 
narrowing from the base, coarsely, closely punctate. Scutellum strongly transverse. Elytra longer 
than in £. conicicollis, and more developed at the sides inferiorly below the humeri (the lower margin 
appearing more strongly sinuate when the insect is viewed in profile); coarsely punctate-striate, the 
interstices convex (when the scales are removed). Ventral segments 1 and 2 very broadly hollowed 
down the middle. All the tibia unguiculate. 
Length 44, breadth 1,%,-2 millim. 
Hab. Mexico, Yucatan (Mus. Brit.). 
Two males: one, without definite locality, in very fresh condition, and labelled with 
the MS. name of Jekel’s used above; the other, from Yucatan, completely abraded, 
and showing how different the sculpture really is when the scales are removed. ‘This 
species differs from the maculate form of H. conicicollis in having the prothorax less 
widened towards the base and sharply fusco-vittate on the disc; the elytra more 
elongate, more developed inferiorly below the humeri, and with the lower margin 
strongly sinuate; and the first ventral segment more broadly excavate, and the fifth 
without numerous erect hairs, in the male. 
3. Eucoleocerus fuscovarius, sp. n. 
Oblong, subovate, narrow, convex, black, the tibie, tarsi, and base of the antenne ferruginous; variegated 
with a dense clothing of whitish and fuscous scales, the dark scales on the prothorax condensed into two 
broad narrowly divided vittz on the disc and a small spot on each side at about the middle, and those 
on the elytra into confluent asymmetrical markings, the scales on the legs and under surface uniformly 
whitish ; the upper surface also set with very short, curled, decumbent, scattered sete, the ventral 
segments 1-4 with adpressed white hairs down the middle. Rostrum as in £. conicicollis; joints 2 
and 3 of the funiculus subequal in length, 1 longer and stouter than 2. Prothorax transverse, convex, 
gradually narrowing from the base, the sides subparallel behind; coarsely, closely punctate. Scutellum 
transverse. Elytra oblong-subtriangular in ¢, subparallel in their basal half in 2 ; coarsely punctate- 
striate, the interstices (as seen with the scales removed) narrow, convex. First and second ventral 
segments hollowed down the middle, and the fifth closely set with short, erect, brownish hairs, in ¢. 
All the tibia in ¢ strongly, in 9 more feebly unguiculate. 
Length 3-4, breadth 14-13 millim. (¢ 9.) 
Hab. Guatemaua, El Jicaro in Baja Vera Paz (Champion). 
One male and two females. Narrower than EL. conicicollis; the prothorax more 
convex, less widened posteriorly, broadly fusco-vittate on the disc, and also with a 
brown spot on each side; the fifth ventral segment of the male clothed with shorter 
hairs,
