a different species, P. dentimargo] the numerous Mexican 

 females agree perfectly with the specimen labelled type. 

 The six males seen all have the antennae distinctly 

 canaliculate. Both localities are on the Atlantic slope. 



29. Polemius medianus, n. sp. 



Moderately elongate, shining, finely pubescent ; nigro-piceous, the 

 head in front ((^) or at the sides before the eyes (2), the basal joint 

 of the antennae beneath, and the pro thorax (a median vitta ex- 

 cepted), stramineous or testaceous, the legs piceous, the femora 

 and base of the tibiae, at least in (J, often testaceous. Head to- 

 gether with the eyes much wider than the prothorax in o, narrower 

 in $ ; mandibles curved in both sexes ; eyes enormously developed 

 in (^, small in $; antennae in ^ about as long as the body, sub- 

 serrate, clothed with short hairs, in $ much shorter and slightly 

 tapering towards the tip. Prothorax {^) transverse, arcuate in 

 front, the sides with a straight, narrow notch at the middle and 

 parallel thence to the rectangular hind angles; ($) a little broader, 

 with the sides somewhat rounded and rather narrowly explanate. 

 Elytra moderately long, a little wider than the prothorax in both 

 sexes, densely sculptured. Tarsal claws as in P. proximus.

Three males and several females. Extremely like P. 

 proximus, and sent with that insect from Teapa, from which 

 it may be distinguished by the enormously developed eyes, 

 the non-canaliculate antennae, and the narrower and less 

 transverse prothorax of the male. The various females 

 somewhat doubtfully referred to P. 7nedianus are only 

 separable from the same sex of P. proximus by their 

 relatively narrower prothorax and darker legs. The single 

 male from Cubilguitz was found placed under P. (Silis) 

 nigrita, Gorh., in the " Biologia " collection ; Silis ocularis, 

 Gorh., (^, has similar eyes. 



30. Polemius hirticornis, n. sp. 



(J. Moderately elongate, shining, finely pubescent; nigro-piceous, 

 the front of the head, the prothorax (a narrow median vitta ex- 

 cepted), and legs (the outer joints of the tarsi excepted) stramineous 

 or testaceous, the elytra piceous. Eyes enormously developed.
