MALACODERMATA., 279 
This fine species is not unlike the variety of C. togatus with black apex to the 
elytra. It is, however, of a clearer and more shining red, and has the head red. The 
prothorax, in all the specimens sent by Mr. Morrison, has two thin linear marks 
like those in C. bilineatus.

About a dozen specimens of the variety, with as many of the typical form of this 
species, were collected by Mr. Champion. ‘The insect is usually wholly pale testaceous, 
with the exception of the antennz, and even these are very pale fuscous; the variety 
has some resemblance to the species now described as C. submarginatus. 
18 (a). Chauliognathus submarginatus. (Tab. VI. fig. 16, 2.) 
Pallide testaceus; elytris albescentibus ; capitis basi; antennis, palpis, thoracis lineolis duabus, elytrorum

Although this is undoubtedly very near to C. exsanguis, I feel convinced it is really 
distinct. The head is black at the base; the thorax is more orbicular and more
