454 HETEROMERA. 
Hab. Panama, David in Chiriqui (Champion). 
A single male specimen. ‘This insect is perhaps nearest allied to C. zunilensis ; but 
differs from it in its less elongate shape, much shorter and less serrate antenne, 
shorter legs, deeper (though fine) punctures of the elytral striz, &e. 
** Sixth ventral segment in the male with strongly-developed lateral lobes, hidden by the 
fifth; the basal joints of the anterior tarsi (except in C. decepta) more or less dilated 
in the male. 
5. Cistela decepta. (Tab. XX. fig. 23.) 
Oblong ovate, obscure reddish- or piceous-brown, opaque, thickly pubescent. Head finely and closely punc- 
tured, the anterior half more sparsely so; eyes (¢) large and rather narrowly separated; antenne (¢ ) 
ferruginous, the apical joints darker, rather slender and about reaching to the first third of the elytra, 
joint 8 short, scarcely twice the length of 2, joints 5-10 elongate-triangular in shape ; prothorax strongly 
transverse, the sides rounded and narrowing from a little before the base, the hind angles obtuse, the 
basal fover very shallow but distinct, the surface finely and densely punctured ; elytra distinctly wider 
than the prothorax, very little rounded at the sides, sculptured as in C. nigricornis ; beneath and the legs 
narrowing at the apex, much as in C. nigricornis, the tarsi, however, more elongate. 
¢. The lateral lobes of the last ventral segment widely separated at the base, abruptly and obliquely incurved 
about the middle, the apices blunt and coarsely setose within ; the central sheath broad and flat, abruptly 
narrowing at the apex, the latter slightly hooked above. (Fig. 23.) 
Length 74 millim.; breadth 33 millim. (¢ 2.) 
Hab. Panama, Volcan de Chiriqui (Champion). 
A single male example. C. decepta is closely allied to C. nigricornis and C. zunilensis, 
but differs from both in its very differently formed last ventral segment in the male; 
it is also narrower than C. nigricornis, and has longer tarsi. 
6. Cistela chiriquensis. (Tab. XX. figg. 24, 24a, ¢ .) 
Ovate, rather broad, moderately convex, piceous- or reddish-brown, scarcely shining, thickly pubescent. Head 
finely and somewhat closely punctured ; eyes (d) rather large, a little smaller and more widely separated 
in the female; antenne—( ¢) moderately long, joint 3 short, only a little longer than 2, joints 4-10 
broad and strongly serrate within, (Q) shorter, joint 3 much longer (though not nearly so long as 4) and 
more slender, joints 4-10 narrower, 9 and 10 triangular and wider than the others—varying in colour 
from brownish-piceous with the basal joints lighter, to ferruginous with the apical three joints piceous ; 
prothorax short, strongly transverse, the sides rounded and converging from a little before the base, the 
hind angles subrectangular, the basal fovese small but distinct, the surtace closely and finely punctured ; 
scutellum closely and finely punctured; elytra comparatively rather short, a little rounded at the sides, 
widest at the middle, rather coarsely punctate-striate, the punctures closely placed, the interstices feebly 
convex and closely and very finely punctured; beneath more shining, sparsely and finely punctured, the 
metasternum and ventral surface more closely so in the middle, the former with coarse impressions, and 
the latter longitudinally wrinkled, at the sides; prosternum narrow ; legs fusco-ferruginous. 
g. Anterior and intermediate tarsi dilated, the first joint of the anterior pair strongly so. The lateral lobes 
of the last ventral segment stout and very widely separated at the base, twisted and very abruptly con- 
stricted about the middle, the narrower apical portions obliquely converging, the latter roughened and
