ART. 8. BUPRESTID BEETLES OF MEXICO—FISHER. 95 
This is the first species of this genus to be described from Central 
America, although the species of this genus extends from the United 
States into South America. When these small and apparently rare 
insects are better known, there probably will be a number of species . 
found in Central America and Mexico. 
Genus EXAESTHETUS Waterhouse. 
Exaesthetus WATERHOUSE, Biol. Centr.-Amer. Coleopt., vol. 3, pt. 1, Suppl., 
1889, pp. 192-193, pl. 9, figs. 15, 15a-e. 
Only one species is described in this genus and, as it is unknown 
to the writer, a copy of the original description is given in full. 
Antennal sockets small, not very approximate. The antennae a little longer than 
the head and thorax together, hairy; the first and second joints moderately large, 
the following ones slender, elongate (Tab. ix, fig. 15a). Thorax convex, transversely 
impressed at the base, finely margined at the sides, the anterior angles deflexed 
and not visible from above. Scutellum elongate, arcuately acuminate (fig. 15b). 
Elytra as broad as the base of the thorax, subparallel, arcuately narrowed at the 
apex, without costae. Prosternum without chin piece; the intercoxal process sub- 
quadrate, obtusely rounded at the apex, almost truncate, and met posteriorly by a 
slight projection of the metasternum. Metathoracic episterna moderately wide, 
subparallel. Posterior coxae of nearly equal width throughout (fig. 15c). Abdomen 
with the first and second segments united into one; the intercoxal process acuminate. 
Legs rather slender; the tibiae straight; the tarsi moderately long, the second and 
third joints with a very small lamina, which is scarcely distinguishable when dry, 
the fourth joints with a rather large, delicate lamina; the claws dilated at their basal 
half (figs. 15d, e). 
I think this very abberant Buprestid may be placed next to Mastogenius. Its 
general appearance is suggestive of Haplocnemus in the Dasytidae. 
EXAESTHETUS DASYTOIDES. 
Elongatus, paullo convexus, nitidus, subtus fere niger, supra nigrescentiaenevg; 
capite leviter convexo, sat crebre subtiliter punctato; thorace antice angustato, 
convexo, sat crebre evidenter punctato, lateribus sat rotundatis; elytris sat crebre 
fortiter punctatis. Long. 2 lin. 
Hab. Mexico, Jalapa (Hége). 
The head has an impression in the middle of the lower part of the face. The thorax 
jis impressed at the base, convex on the disk; the punctures are very distinct, rather 
close together. The elytra have the punctures rather strong and moderately close 
together.
