DECASTICHA.—CLZOTEGES, 275 
4. Decasticha decemguttata, sp.n. (Tab. XII. fig. 24, ¢.) 
S$. Oblong, narrow, moderately shining, black; above rather sparsely, the under surface densely, clothed 
with glittering green, golden, and blue scales, which are here and there clustered into small spots on the 
elytra, the elytra also each with five rather larger patches of pallid scales (two placed transversely at 
about the basal fourth—one on the fourth interstice and one near the lower margin beneath,—two 
placed transversely on the outer part of the disc beyond the middle, and one near the apex); the surface 
also set with scattered decumbent minute sete, Head and rostrum sparsely punctate, the rostrum 
longer than broad, obsoletely canaliculate to the rather deep inter-ocular scales; antennal scape not 
reaching the posterior margin of the eyes, the latter large, rounded, and moderately prominent. 
Prothorax nearly as long as broad, bisinuate at the base, the sides becoming parallel posteriorly and 
converging in front; sparsely punctate and with coarser punctures along the flanks, the dise with a 
large, deep, horseshoe-shaped excavation preceded by a short median sulcus. Scutellum large. LHlytra 
elongate-triangular, flattened towards the suture, mucronate at the tip, the humeri obliquely truncate 
in front ; with ten rows of rather coarse punctures, the interstices closely punctulate and almost flat. 
Length 9, breadth 24 millim. 
Hab. Costa Rica (Mus. Brit., ex coll. Sharp). 
One male, rather worn above, probably captured by Biolley. Very hike Hrophthalmus 
jekelianus (= stellaris, Pasc.), but with ten striz only on the elytra, the elytra them- 
selves narrowing from the base and flattened along the suture; the rostrum feebly 
canaliculate (instead of carinate); the prothorax more elongate; the legs and antenne 
shorter. The elytra are shorter and differently marked, and the eyes much larger, than 
in D. tetrastigma. 
CLAOTEGES. 
Cleoteges, Pascoe, Ann. & Mag. Nat. Hist. (5) v. p. 427 (1880). 
Rostrum with a large triangular or subcordate bare nasal plate, the declivous horseshoe-shaped subapical 
portion limited laterally by a sharp carina, the carine sometimes extending longitudinally backwards, 
- the scrobes very deep, sinuous, lateral, running to beneath the eyes, the latter large, not strictly lateral, 
oval as seen from above ; scutellum small; elytra much wider than the prothorax, 10-striate, the outer 
striz entire, the humeri prominent; first ventral suture feebly sinuate; femora dentate; all the tibie 
unguiculate in both sexes ; body oblong, squamose, winged. 
Type, C. virosus, Pase. 
Four species are now known of this well-defined genus, all peculiar to Central 
America. They may be separated by the following elytral characters :— 
Third interstice with a prominent, curved, abruptly terminated ridge, the 
suture raised behind the scutellum. . . . . . . 2. 2...) e) «Ovtrosus, Pase.

ridge, the suture not raised at the base . . . . . . oe + « + granulosus, sp. 0. 
Third and fifth interstices each with a series of tubercles, the terminal one

1. Cleoteges virosus, (Tab. XII. fige. 25, 25a, 2; 256, wing.) 
Cleoteges virosus, Pascoe, Ann, & Mag. Nat. Hist. (5) v. p. 428°. 
g. Elytra oblong-subtriangular, with a short straight dentiform prominence at the sutural angle. 
@. Elytra broader, suparallel to near the middle, and with a longer and stouter tooth at the sutural angle. 
Length 84-123, breadth 3-42 millim. (¢ 2.)
