23 (s). Chauliognathus forreri. 
Flavo-ochraceus, opacus ; antennis, palpis, tibiis tarsisque nigris ; capite inter oculos nigro bimaculato ; prothorace 
maculis sex nigris, duabus anterioribus et duabus intermediis cuneiformibus, duabus basalibus transversis. 
Long. 11 millim. 9. 
Hab. Mexico, Ventanas 2000 feet (Forrer). 
I have as yet seen only three females of C. forreri. It is allied to a South-American 
species, the Telephorus scriptus of Germar and Castelnau, but is to be distinguished by 
the yellow head. 
23 (c). Chauliognathus hieroglyphicus. 
Sordide flavus, subnitidus ; capite, antennis, palpis, pectore, tibiis tarsisque nigris; prothorace nigro-maculato, 
maculis plus minusve confluentibus, scutello elytrorumque basi maculis duabus nigris. Long. 83- 
9 millim. g 2. 
Hab. Mexico, Guanajuato (Dugeés, coll. Sallé). 
This species is in the markings of the thorax allied to the preceding, but it is of a 
shorter form, and shining instead of opaque. It is, moreover, very different in many 
details. The head is wholly black in all the individuals, eight in number, which I have 
yet seen. The thoracic spots are, typically—a wedge-shaped one in the middle of the 
front of the disc, an irregular one on each side of the middle of the base (formed of 
the transverse basal and two intermediate spots of C. forreri united), and an oblique 
one on each side not touching the margin; these spots coalesce in various degrees, 
the last to unite being the oblique lateral ones; in one example they are reduced to six 
as in C. forreri, but the other differences remain the same. The abdomen is spotted 
with black ; the male has the valvular plate yellow. 
23 (p). Chauliognathus subulipennis. 
Latus, sordide rufus; ore, antennis, palpis, femoribus apice, tibiis tarsisque nigris ; elytris opacis, fuscis, postice 
valde attenuatis, margine basali et laterali, epipleurali versus apicem late, et sutura tenuiter rufis; pro- 
thorace valido, subquadrato, punctis quatuor sulcoque mediano obsolete impresso. Long. 13 millim. 9¢. 
Hab. Mexico, Tehuantepec (Sumichrast). 
A species not very nearly allied to any other here described, but which, in the absence 
of the male, cannot be very satisfactorily compared. Its broad thick build, with the 
elytra strongly narrowed from the rather wide base almost to a point at their apices, is 
alone sufficient for its recognition. The antenne are rather long, and I observe that 
their third joint is nearly as long as the fourth, instead of being, as in some species of 
this section, much shorter. Three female specimens. 
25 (a). Chauliognathus —— ? 
Hab. Mexico, Puebla (Sallé). 
A single female example of a black Chauliognathus with a red thorax is probably 
distinct from C. collaris.
