85. Ophthalmolampis albolineata sp. nov. 



Most nearly related to 0. colubri Saussure, but somewhat larger 

 and differently colored. Its habitat, too, is quite widely removed 

 from that of Saussure's species. 



Head about as wide as the anterior portion of the pronotum, a 

 little shorter than the front lobe of the latter; face decidedly wider 

 than long, the front coarsely and deeply punctulate below the trans- 

 verse groove: eyes large and prominent, strongly divergent, separated 

 at the vertex by a space no greater than the diameter of the second 

 antennal joint; the fastigium depressed, rather small, plainly longi- 

 tudinally sulcate; frontal costa smooth, not especially prominent 

 between the antenna, where it is about two and one-fourth times the 

 width of the narrowest part of the vertex; antenna? slender, filiform, 

 about as long as the tegmina; occiput punctulate. Pronotum sub- 

 cylindrical, rugoso-punctulate, the posterior lobe gently expanding to 

 the rear; transverse sulci well defined and severing the lateral pallid 

 lines of the disk; anterior edge widely and angulately emarginate at 

 middle, the hind margin broadly rounded. Tegmina for the most 

 part coriaceous. Pleura strongly and coarsely punctulate, closely 

 veined, gently tapering, about two-thirds the length of the abdomen. 

 Hind femora robust at base, the carinae prominently serrated, and the 



5 The species yersini Saussure very likely belongs in the present section also, but 

 the description is too incomplete to permit of its tabulation.
