CAMARIA.—MOPHON. 247 
acuminate, horizontal, the apex much produced and received by the deeply concave V-shaped mesosternum ; 
beneath shining, brownish-eneous, the ventral surface longitudinally wrinkled. 
Length 233 millim. (¢.) 
Hab. Panama, Bugaba (Champion), Chiriqui (Zrétsch). 
This species is allied to the undescribed C. wraria, Dej., of South America; in the — 
structure of the head it approaches C. clandestina, Pasc., from Para. 
Two examples, both males.

nulla). 
This genus contains about six species, all of large size; three only have been 
described as yet. Blapida is confined to the tropical regions of the New World; one 
species is now known to inhabit Central America; the genus ranges from the Amazon 
valley to Guatemala. The different species bear a certain superficial resemblance to 
the Buprestide ; all have the apex of each elytron produced into a sharp spine. 
1. Blapida neotropicalis. (Tab. XI. fig. 5, ¢ .) 
Dull greenish-bronze, rarely reddish-brown tinged with green. Head very finely and clasely punctured, the 
vertex more sparingly so; prothorax broader than long, subquadrate, scarcely narrowing anteriorly, the 
sides straight from the middle to the base, the anterior angles rather broadly rounded, the posterior angles 
rectangular, the surface exceedingly finely and rather sparingly punctured ; elytra deeply striate, the 
strie in some examples very closely, finely, and subtransversely punctured throughout, in others obsoletely 
so towards the suture, the interstices slightly convex, smooth, dull greenish-yellow in light-coloured fresh 
examples, obscure brownish-olivaceous in dark-coloured faded specimens, the striz more or less stained 
with grass-green, the terminal spines strong and darker in colour ; legs varying in colour—red, reddish- 
brown, or dark bronze ; intermediate tibie widened on the inner side at the apex in the male; beneath 
dark bronze, shining, almost imperceptibly punctured. 
Length 18-21 millim. (¢ 2.) 
Hab. Guatemata, El Jicaro in Vera Paz (Champion); Nicaragua, Chontales (Belt, 
Janson, coll. F. Bates). 
Numerous examples. We figure a light-coloured male from Chontales. An allied 
undescribed species is found in Southern Colombia. 
MOPHON. 
Mophon, F. Bates in litt. 
Mentum trapezoidal, deflexed at the sides; last joint of the labial palpi very broad, rounded at the apex, that 
of the maxillary pair broad and securiform ; mandibles truncate at the apex; head large, not deeply sunk 
into the prothorax, the epistoma short, well defined, broadly truncate in front, and separated from the 
prominent labrum by a membranous clypeus, the antennary orbits slightly swollen and rounded externally ;
