MORDELLISTENA. eas 349 
cinereo-pubescent fascize. ‘The pubescence of the elytra is rather sparse and the punc- 
tuation comparatively coarse. M. palpalis belongs to the subgenus Tolida, Muls., as 
defined by Emery. 
73. Mordellistena pulicaria, 
Short, cuneiform, black, finely pubescent, the elytra with two cinereo-pubescent fasciee—one basal, the other 
postmedian,—the rest of the pubescence partaking of the ground-colour. Head short and broad; palpi ( 2 ) 
fusco-testaceous, the last joint of the maxillary pair oblong-ovate with the apex obliquely truncate; 
antennee ( 9 ) fusco-testaceous, very short, joints 3 and 4 narrow, subequal, 5-11 a little thickened, 5-10 
as broad as long, 11 longer than 10; prothorax transverse; elytra short, gradually narrowing from the 
base; beneath black, the sides of the breast in front and of the venter cinereo-pubescent ; pygidium mode- 
rately long; legs piceous, the anterior pair obscure testaceous, the hind tibial spurs testaceous ; the hind 
tibiee with two ridges towards the tip—the first obliquely extending across the outer face of the tibia, the 
other short, subapical; the first joint of the hind tarsi with a single ridge. 
Length to end of the elytra 14, to tip of the pygidium 13, millim. ( 9.) 
Hab. GuateMata, Zapote (Champion). 
Though we have but:a single female example of this little insect, I do not hesi- 
tate to give ita name. It comes nearest to W/. perexiqua, but differs from that species 
in its finer pubescence, smaller head, and shorter elytra, the latter with the anterior 
fascia at, not below, the base. The pygidium is also shorter, and the first ridge on 
the hind tibie extends across their outer face. ‘The species is of about the same size 
and build as WV. minutissima. 
74. Mordellistena fasciculata, (Tab. XV. figg. 25; 25a, maxillary palpus.) 
Very elongate, narrow, subparallel, black, the sides of the prothorax narrowly and the pygidium reddish ; the 
prothorax with the base narrowly and an indistinct line on either side of the disc, the scutellum, and 
numerous small, transverse, partly confluent spots scattered irregularly all over the elytra golden-pubescent, 
the rest of the pubescence on the prothorax and elytra black, that on the head yellowish, the pubescence 
coarse and somewhat dense. Head rather small, the eyes not very large; palpi very elongate, testaceous, 
the last joint of the maxillary pair elongate-triangular, moderately stout, its inner and apical sides about 
equal in length and very much shorter. than the outer side, the latter slightly concave, the apical side 
rounded; antenne obscure testaceous, very slender, filiform, moderately elongate, joint 3 narrow, short, 
4 considerably longer than 3, 5 longer than 4 or 6, 5-11 elongate, 6-10 subequal, 11 longer than 10 ; 
prothorax transverse, much wider than the head; elytra very elongate, more than four times the length 
of the prothorax, subparallel in their basal half; beneath black, the apical margin of each ventral segment 
testaceous ; pygidium elongate, slender, more than twice the length of the hypopygium ; legs testaceous, 
the middle and hind femora, the hind tibiz in part, and the extreme tips of the tarsi piceous; the hind 
tibie with a short subapical ridge only; the first joint of the hind tarsi with traces of several oblique 
ridges. 
Length to end of the elytra 3-4, to tip of the pygidium 33-43, millim.; breadth 3-1 millim. 
Hab. Mexico, Omilteme in Guerrero 8000 feet (H. H. Smith). 
Two examples, probably females. This peculiar species has a subapical ridge only 
to the hind tibie, and in this respect agrees with Mordella; but it evidently belongs 
to Mordellistena, the following closely allied form being intermediate between it and 
those species with the ridges on the hind legs not very sharply indicated. The larger
