352 HETEROMERA. 
middle; elytra moderately long, gradually narrowing from the base, rounded at the apex; lege and under 
surface pitchy-brown or reddish, the latter densely pubescent. 
Length 77-10 millim. 
Hab. Mexico, Jalapa (Hoge). 
Two female examples. P. lineata differs from all the species described by Gerstacker 
in having the three basal joints only of the antenne simple. 
3. Pelecotomoides bivittata. 
Pelecotomoides bivittata, Chevr. in litt. 
Q. Closely resembling the same sex of P. lineata, but differing as follows:—The antennex entirely reddish, 
with the five basal joints simple—2 and 3 very short, 4 and 5 wider, about as broad as long, 5 a little 
wider than 4,—6-10 very strongly serrate, 6 twice as wide as 5; the brownish-pubescent median vitta of 
the prothorax more dilated at the middle and less sharply defined ; the longitudinal golden-pubescent vitta 
on each elytron wider and less oblique, extending inwards in front and reaching the base, the brown pubes- _ 
cence on the rest of the surface with intermixed golden hairs. 
Length 83 millim. 
Hab. Mrxico, Cordova (Salié). 
One female example. Closely resembling the same sex of P. lineata, but differing 
from it by the small non-serrate fourth and fifth joints of the antenne. This specimen 
has the seventh antennal joint on one side abnormally formed, it being biserrate. 
P. bivittata agrees in some respects with the description of P. bistriata (Gerst.), from 
Peru; but it cannot be satisfactorily identified therewith. As in P. lineata, the elytral 
stripes are confluent at the suture a little before the apex. 
A second specimen from Cordova (Sad/é) has the upper surface very densely and 
uniformly greyish-yellow-pubescent; it may be a variety of P. bivittata, or it may be 
referable to P. helva, Perty (the figure of which it closely resembles), but as the 
antenne are broken off it is impossible to identify it. P. helva (2), according to 
Gerstacker, has the five basal joints simple, the third joint twice as long as the second. 
4. Pelecotomoides nebulosa. (‘Tab. XVI. figg. 4, 40,9.) 
Q. Moderately elongate, rather broad, brown or blackish-brown, thickly pubescent, densely and finely punc- 
tured; the pubescence yellowish-grey, more or less mottled with fuscous (the dark hairs showing a 
tendency to form a median patch on the prothorax, and transverse, irregular, partly confluent patches on 
the elytra). Head small; the eyes widely separated, deeply emarginate, finely granulated; antennz rather 
short, black or piceous, with the five basal joints more or less rufous, joints 2, 4, and 5 very short, 3 about 
twice as long as 2, 5 acutely produced within, 6-10 very strongly serrate, 6 nearly twice as long and twice as 
wide as 5; prothorax convex, about as long as broad, with the sides a little rounded and rapidly converging 
from the base, the hind angles acutely produced behind, the basal lobe emarginate in the middle ; elytra 
moderately long, gradually narrowed from the base, a little flattened on the disc anteriorly, obtuse at the 
apex, the apices slightly divergent and somewhat angular; beneath brown or reddish-brown, densely 
cinereo-pubescent, the apical ventral segment with some brown pubescence at the tip; legs pitchy-brown 
or reddish, the tibial spurs black. 
Length 74-11 millim. .
