Mas. — Abdominis segmentis quinto et sexto Uictc flavi?, 

 nitidis. 



Femina. — lisden in medio et ad latera fusco notatis. 



The oblong form nearly evenly rounded in front, and at 

 the apex of the elytra combined with the fuscous elytra, of 

 "which only the extreme margin, tlic suture, and the raised 

 nervures are paler, will readily distinguish this from any 

 of the section A. The discoidal nervure is costate, nearly 

 straight, not reaching the apex ; between this and the 

 suture is a second, but finer and less raised, and vanishing 

 at two-thirds of the elytral length. The body beneath, the 

 legs and antennae are entirely pitchy, with only the dia- 

 phanous segments paler.

Aspidosoma costatum, n. sp. 



Oblongo-ovale, thorace macula transversa basali, vitta 

 mediana, utrinque miniata piceis, maculis lateralibus paulo 

 distinctis ; elytris fusco-piceis, bicostatis, sutura et costis 

 tenuissime, margineque laterali latius pallidis. 



Long. lin. 4 — 5. (5", ? . 



Head, body beneath and legs pale, more or less clouded 

 with fuscous ; thorax pale and sub-diaphanous, markings 

 as in hilineatum,, but the lateral spot only indicated by a 

 darker spot about the middle of the margin. Elytra with 

 the discoidal costate nervure well marked and the callus 

 strongly raised.

The females of this genus are still unknown. I have 

 nine examples before me, all of which are males. The 

 dorsal abdominal plates are wide and lobed, or acutely 

 angled at the sides. The eyes are enormous, and the 

 antennas short and rudimentary; their apical joint termi- 

 nates in one or more mucronatc points. The species seem 

 readily divisible by the proportions of the antennal joints, 

 and by the form of the pygidium.
