CISTELA. 453 
very shallow, the surface finely and densely punctured ; scutellum closely and finely punctured ; elytra a 
little more shining than the prothorax, slightly rounded at the sides, shallowly and very finely punctate- 
striate, the punctures becoming still finer towards the apex, the interstices flat and thickly punctured ; 
beneath finely and closely punctured ; legs fusco-testaceous, slender ; the tarsi similar in both sexes, their 
antepenultimate joint somewhat produced beneath. 
g. Abdomen with a short but hidden non-lobed sixth ventral segment; the central sheath laterally com- 
pressed. 
Length 53-73 millim. ; breadth 23-34 millim. (¢ 9.) 
Hab. Guatemata, Cerro Zunil 4000 feet, Sinanja, Senahu in Vera Paz 3000 feet 
(Champion). 
Numerous examples from Cerro Zunil and one only from each of the other localities. 
Narrower and smaller than C. nigricornis; the tarsi more slender, the first joint of the 
two hinder pairs more elongate, the central sheath of the cedeagus not hooked at the 
apex, &c. The description is made from the Zunil examples, the others being in a 
mutilated condition. 
3. Cistela cinerascens. 
Oblong ovate, somewhat depressed, piceous-brown, opaque, thickly clothed.with ashy pubescence. Head finely 
and rather closely punctured; eyes ( ¢ ) very small and very widely separated ; antenne ( ¢) long, fully 
reaching to the middle of the elytra, joint 3 short, about half the length of 4, joints 4-10 subserrate 
within, piceous; prothorax broad, strongly transverse, widest about the middle, the sides rounded, and 
narrowed a little posteriorly and more strongly so in front, the hind angles obtuse, the basal fovese 
obsolete, the disc shallowly longitudinally impressed in the middle behind, the surface very finely and 
densely punctured ; scutellum minutely punctured; elytra the width of the prothorax at the base, a little 
rounded at the sides, finely and shallowly punctate-striate, the punctures closely placed, the interstices 
very feebly convex and closely and minutely punctured; beneath closely and finely punctured; legs 
slender, fusco-ferruginous, the tarsi undilated in the male. 
g. Abdomen with a short but hidden non-lobed sixth ventral segment ; the central sheath slightly compressed. 
Length 5? millim.; breadth 23 millim. (¢.) 
Hab. Mexico, Matamoros Izucar (Hodge). 
A single male example. This species may be at once distinguished amongst its 
allies by the small and widely separated eyes (much smaller and more distant than in 
the females of the allied forms), and by the thorax being widest about the middle and 
very distinctly narrowed behind. It is, perhaps, nearest allied to C. nigricornis. 
4, Cistela calida. 
Ovate, rather convex, brownish-castaneous, slightly shining, thickly pubescent. Head finely and rather closely 
punctured ; eyes ( ¢) large and somewhat narrowly separated ; antenne (¢ ) rather short, about reaching 
to the first third of the elytra, joint 3 short, not twice the length of 2, joints 4-10 subserrate within, 
fusco-ferruginous, lighter towards the base ; prothorax strongly transverse, the sides rounded and 
narrowing almost from the base, the hind angles subrectangular, the basal foveee shallow but distinct, 
the surface densely and finely punctured ; scutellum closely punctured ; elytra rounded at the sides, finely 
but rather deeply punctate-striate, the interstices almost flat and closely punctured; beneath finely and 
sparsely punctured, the ventral surface more closely so along the middle, the metasternum with scattered 
punctures ; legs ferruginous ; the tarsi not dilated in the male. 
g. Abdomen with a short but hidden non-lobed sixth ventral segment; the central sheath somewhat com- 
pressed, and hooked at the apex above. 
Length 5} millim. ; breadth 23 millim. (¢.)
