CHAULIOGNATHUS. 77 
27. Chauliognathus scapularis. 
Callianthia scapulata, Sturm coll. 
Nigro-fuscus ; prothorace (punctis duobus nigris), plaga humerali, femoribus ad apicem, tibiisque flavis, abdo- 
mine segmentis singulis basi fuscis flavo marginatis. Long.11 millim. @Q. 
Hab. Muxico (Sturm, coll. Sallé). 
- The coloration of the elytra of this species is common to a great number of Mexican 
beetles both of this and of other families ; but this is not liable to be confounded with 
any other ; for the shining yellow thorax with two black round dots placed one on each 
side of the disk is only common to it and to C. collaris. 
The shoulder-stripe extends rather more than a third of their length down the elytra, 
and includes the whole callus and reflexed margin of the shoulder. ‘The antenne are 
wanting in the single female specimen, with the exception of the first two joints, which 
are black. ‘The apex of the elytra is very narrowly yellow; and they probably vary, as 
other species of the genus do, in the amount of the black and yellow colours. 
28. Chauliognathus morio. 
Callianthia morio, Sturm coll. 
Statura omnino Photini perelegantis, at aliquid major. Nigro-fuscus, opacus ; capite maculis duabus lateralibus 
ante oculos, prothoracis limbo frontali et laterali et margine reflexo, elytris sutura et margine tenuissime 
flavis ; antennis compressis, serratis. Long. 15 miliim. Q. 
Hab. Mexico (Sturm, coll. Sallé). 
Remarkably resembling some Photini, perhaps most an undescribed species of the 
eroup to which my Photinus perelegans belongs. 
The head is as long as in typical Chauliognathi; but the antenne are rather those of 
Daiphron. I should not be willing to admit it into that genus, however, at present, 
because the elytra are very parallel, and are long even for the present genus. The 
thorax is subquadrate, with a well-marked central channel in the centre of the disk. The 
scutellum and base of the elytra are fuscous. The pale margin begins immediately 
below the humerus; it is faint at the apex. The suture is entirely pale. ‘The elytra 
are finely coriaceous, rather more coarsely so at the base. The antenne are not more 
than half the length of the body. 
A single example only in Sallé’s collection, from that of Sturm.

Long. 11-14 millim. SQ.
