MALACODERMATA. 333 
appearance of a Tillus, but the structure is not very different from that of the European 
TL. elongatus, and the claws are those of the genus. The size of our specimens is three 
and a half to four millimetres. The colour is entirely black, excepting a red patch 
covering nearly the whole of the upper surface of the thorax in the larger specimen. 
The smaller one is not so deeply coloured, being perhaps not quite mature, its legs 
accordingly are pitchy. . 
The insect, as is the case with 7’. elongatus, at least in England, is probably not often 
met with. 
CYMATODERA (p. 130). 
Cymatodera parallela (p. 132). 
To the localities given, add :—Panama, Bugaba, Volcan de Chiriqui 4000 to 6000 feet, 
Tolé (Champion). | 
The Bugaba specimens are rather less parallel than typical ones, and the subapical 
patch is developed into a broad somewhat arcuate fascia. 
Several specimens occurred. 
8 (a). Cymatodera sericans. 
Elongata, postice latiuscula, brunnea, obsolete seriatim punctata, subtus picea, subtilissime breviter sericeo- 
pubescens ; antennis pedibusque ferrugineis, interstitiis crebre, subtiliter irregulariter, punctatis. Long. 
15 millim. | 
Hab. Payama, Volcan de Chiriqui 4000 to 6000 feet (Champion). 
Head and thorax very finely and very closely punctate, the ocular canthus raised into 
a ridge which is prolonged over the insertion of the antenne to the base of the man- 
dibles; disc of the thorax finely wrinkled, but the wrinkles not so conspicuous as the 
punctures. Elytra gradually widening from the base to one fourth before the apex, 
which is quite simple, neither cut out nor sinuate; the eight series of punctures are 
not deep nor very even, and towards the apex become longitudinally confluent and - 
evanescent. The breast and abdomen are piceous; the latter with indistinct rufous 
spots on the sides of the four basal segments, which are clothed with shining silky hair, 
as is also the fifth segment, which is, in the male, rather broadly and angularly emargi- 
nate; a small sixth ventral segment is present, also cut out at its apex, but not deeply. 
The antenne have the apical joint scarcely longer than the tenth, acuminate. 
Difficult as the determination of the Cymatodere is, there is no species of our fauna 
yet described to which this could with propriety be assigned. It most nearly resembles 
C. lunulata, but the form of the body, its nearly unicolorous tint, rufous legs, &c. 
appear to me to indicate a distinct species, even if its larger size were not taken into 
account. 
One example.
