This variety has a strong resemblance in colour and 

 facies to Hcmilophus iirolixns, Bates, from which it may, 

 however, be easily distinguished by the structure of the 

 antennae. 



Malacoscylus hirittatus, sp. n. (PL XIL, j&g. 15, (? ). 



Niger, griseo vel fulvo-griseo sat dense pubescens ; capita supra 

 vittis duabiTs albidis, autice convergentibus et inter antennas con- 

 junctis ; prothorace elytrisque utrinque albido-vittatis ; elytris ad 

 apices angustim rotundatis ; carinis lateralibus paullo pone apicem 

 evanescentibus. Long. 11 — 14 mm. 



( (^ ). Antennis quam corpore vix brevioribus ; articulo 3o qnam 

 lo vel 4o sesqui longiori ; articulis 3o, 4oque basi testaceis. 



(?). Antennis dimidium corporis vix excedentibus ; articulo 

 3o inci'assato dense sed breviterque nigro-finibviato, quam articulo 

 lo vel 4o paullo longiori ; articulis 4o ad 6urQ plus minusve 

 testaceis. 



Hah. Mexico, Omilteme (8000 ft.) and Chilpancingo 

 (4600 ft.) in Guerrero {H. H. Smith). 



The diverging dingy white vittse of the vertex of the head are 

 continuous behind with the two vitta?, one on each side, of the 

 prothorax ; these again join at the base the two vittae which run 

 along the elytra, one on each side immediately above the lateral 

 carina. The prothorax and elytra are rather strongly and thickly 

 punctured, the prothorax somewhat less thickly than the elytra. 

 At the apex each elytron is narrowed to an obtuse jpoint, and in 

 this region the punctures are almost obsolete. 



This species differs from the other members of the 

 genus in the rather narrow apices of its elytra ; and, in 

 common with the preceding species, it differs in one or 

 two other important respects from the more typical repre- 

 sentatives of the genus. The third joint of the antennae is 

 relatively much shorter in both sexes, and in the female 

 it is very distinctly thickened. The head also does not 

 exhibit the broad depression above between the antennal 

 tubercles, which is to be seen in M. cirratm, Germ., and 

 other South American species. 



Lycidola levipennis, sp. n. (PI. XIL, fig. 1). 

 Nigra, fulvo-fasciata ; el3'tris pone tertiam partem basalem 

 fortiter dilatata, apice late nigro-cyanea, submetallica ; antennis 

 ( 2 ) apicem elytrorum baud attingentibus, articulis tertio quarto- 

 que crassatis, subtequalibus, dense ciliatis, utrisque quam primo 

 paullo longioribus. Long. 26, lat. ad hum. 9 mm.
