COTINIS.— GYMNETIS. 353 



16. Cotinis pulverulenta. (Tab. XXII. fig. 10, c? .) 



Cotinis pulverulent a, Burm. Handb. der Ent. iii. p. 262 \ 

 Cotinis gracilis, Sharp, Journ. Linn. Soc, Zool. xiii. p. 137 2 . 



Hab. Mexico \ Mirador (Salle), Almolonga (Edge), Valladolid in Yucatan (Gaumer) ; 

 British Honduras, Cayo (Blancaneaux) ; Honduras 2 . 



Burmeister mistook a (probably slender) female example for the male, and described 

 both sexes as having sharply tridentate anterior tibise and the scattered scaly clothing 

 as changing into scaly hairs on the under surface and legs. But the true males, in fact, 

 have remarkably slender fore tibiae, with no conspicuous tooth except the long curved 

 terminal one ; the second tooth is only slightly indicated, and in some examples entirely 

 wanting, and the uppermost tooth is a very short sharp spine. The males have scattered 

 oval scales over the entire body and legs ; in the females the scales change on the 

 pygidium, under surface, and legs into more or less slender hairs. In length the species 

 varies from 17 to 21 millim., and in width from 7^ to 12 xnillim. C. gracilis, Sharp, 

 is founded on a slender male example. 



We figure an individual from Mirador. 



17. Cotinis adspersa. (Tab. XXI. fig. 14.) 



Cotinis adspersa, Sharp, Journ. Linn. Soc, Zool. xiii. p. 136 l . 

 Hab. Nicaragua, Chontales (Belt 1 ). 



A very distinct species. The frontal horn is much raised and laterally compressed, 

 with a rather long free end pointed and curving downwards ; in C. pulverulenta it forms 

 a scarcely perceptible longitudinal swelling, free at the end through the deep pit-like 

 depression of surface of the clypeus. 



18. Cotinis ? 



Hab. Mexico, Santa Clara in Chihuahua (Hoge). 



One example, crushed and distorted, of an evidently new species allied to C. antonii.
