456 HETEROMERA. 
Hab. GuatTeMALA, Las Mercedes 3000 feet (Champion). 
One male example only, differing as above from the corresponding sex of C. deli- 
tescens. 
9. Cistela juquile. 
Oblong ovate, rather depressed, piceous-brown, opaque, thickly pubescent. Head finely and rather sparsely 
punctured ; eyes (2) rather small, widely separated; antenne (2) ferruginous, moderately long, joint 3 
about twice as long as 2, and much shorter than 4, joints 4-10 narrowly elongate-triangular ; prothorax 
moderately transverse, the sides parallel behind and rounded and narrowing from about the basal third, 
the hind angles subrectangular, the basal fovew very shallow, the surface finely and somewhat densely 
punctured ; elytra a little rounded at the sides, finely and very shallowly punctate-striate throughout, the 
interstices flat and closely and minutely punctured, the humeri very little rounded; beneath finely and 
rather sparsely punctured ; legs ferruginous, the tarsi rather stout. 
Length 8 millim.; breadth 32 millim. (?.) 
Hab. Mexico, Juquila (Sallé). 
Two female examples. This insect closely resembles C. decepta, but differs from it in 
the thorax being less transverse, with the sides more parallel behind and the disc less 
densely punctured, and the elytra more depressed and with less rounded humeri. From 
the corresponding sex of C. delitescens its larger size and stouter limbs sufficiently 
distinguish it. I include C. jyugut/e provisionally in this section of the genus, it having 
considerable affinity in many of its characters with C. delitescens. 
10. Cistela alternans. (Tab. XXI. fig. 1, ¢.) 
Oblong ovate, depressed, obscure reddish-testaceous, subopaque, sparsely clothed with short pubescence. Head very 
finely and sparsely punctured ; eyes(d) rather small; antenne (< ) reaching to the middle of the elytra, 
rather stout and gradually widening outwardly, joint 3 shorter than 4, joints 4-10 long and subtriangular, 
testaceous, the last three or four joints darker ; prothorax short, transverse, the sides rounded and con- 
verging from a little before the base, the hind angles obtuse, the basal fovec rather deep, the surface very 
finely and rather closely punctured, the anterior half of the disc more sparsely so, the disc somewhat flat- 
tened, and broadly suffused with fusco-piceous ; scutellum very finely and closely punctured; elytra sub- 
parallel in their basal half, rounded at the shoulders, finely and shallowly punctate-striate, the interstices 
quite flat and thickly punctured, the alternate ones fusco-piceous; beneath finely and rather closely 
punctured, the sides of the metasternum coarsely and sparsely punctured in front and smooth behind, the 
venter darker at the sides ; anterior and intermediate coxe narrowly separated; metasternum moderately 
long ; legs testaceous, long and slender. 
g. Anterior and intermediate tarsi slightly dilated, the first joint of the anterior pair rather broadly so. The 
lateral lobes of the last ventral segment curved, their apices bluntly rounded off and clothed with longish 
hairs. 
Length 63 millim.; breadth 22 millim. (¢.) 
Hab. Mexico, Yolotepec (Salié). 
A single male example. This species departs widely from the allied forms in the 
system of coloration of the elytra, the alternate interstices being of a darker colour 
than the others.
