14. Cypherotylus aspersus. (Tab. VI. fig. 9, $ .) 



Oblongus, antice posticeque acuminatus, niger, opacus; prothoraee trapezoideo, lateribus fere rectis, antice 

 angustato ; elytris sordide ochraceis, pallidis, punctis numerosis impressis nigris (ssepe confluentibus, 

 in serie duplici interdum positis). Long. 14-17 millim. $ . 



Hab. Mexico, Pinos Altos in Chihuahua (Buehan-Hepburn), Santa Clara in Chihuahua 

 {Edge). 



Var. Elytris punctulis minus numerosis, lateribus macula nigra. 



Cypherotylus Boisduvali, Crotch, Trans. Am. Ent. Soc. iv. p. 358 * (nee Chevr., Lacord.). 

 Hab. Noeth Ameeica, Colorado x (Snow, coll. Gorham), New Mexico 1 . 



Very closely allied to C. fenestratus, but with the thorax black. Both species are at 

 once separated from C. boisduvali by the depressed and apparently always soft elytra, 

 by the small trapezoidal thorax, and by the whole insect being dull. I have not seen 

 a male which I can refer to this species. The specimens from Colorado in my collec- 

 tion were received under the name C. boisduvali, but they are not referable to that 

 species. 



15. Cypherotylus ? 



Hob. Beitish Hondueas, Cayo (Blancaneaux). 



A single discoloured specimen of a Cypherotylus of a species unknown to me, and not 

 matured when captured. 



MICREROTYLUS. 



Micrerotylus, Crotch, Cist. Ent. i. p. 541 (1876). 



The species which Crotch took for his type of this species, viz. M. gronovii (Herbst), 

 was placed by Lacordaire in Brachysphenus, in the section Barytopus, with other 

 members of which, however, it has little connection. The six species included by 

 Crotch have a very similar form and mode of pattern, and one or two are doubtfully 

 distinct as species. There is nothing but general form and style of pattern to separate 

 them generically from either Brachysphenus or Erotylus ; and they approach very 

 closely to some Zonarii, such as Z. indicus. They are all from Tropical South America, 

 from the Amazons northwards, and one species occurs in Central America. 



1. Micrerotylus lunulatus. (Tab. VI. fig. 13.)
