femora less strongly inflated basally than is usual in the genus, 

 surpassing the abdomen in both sexes. Hind tibiae with seven spines 

 in the outer row. Entire insect somewhat hirsute. 



General color above greenish-olive with the face and cheeks a 

 trifle paler: sides of basai abdominal segments piceous, the apical 

 two-thirds of that of the maie testaceo-vinaceous, below paler. 

 Antennae olivaceous as are also the legs including the hind tibiae.

Hah. Peru, about fifty miles to the eastward of Cerro de

 séries of botli sexes at hand. 



Ommatolampis lignicola, sp. n. 



A little smaller and somewhat slenderer species than 0. per- 

 spiciUafa which is considerably darker colored and varied with 

 stripes of duU testaceous on the sides of the pronotum and the 

 face. Tegmina sublinear, nearly reaching the hind edge of the 

 first abdominal segment, the heavy veins pale with tlie interspaces 

 dusky. Entire head, thorax and the dorsum of the abdomen rugulose 

 and coarsely punctata but not quite so strongly as in the insect 

 to which it bas been compared. Head moderately large, a trifle 

 wider than the front edge of tiie pronotum, the face gently rece- 

 ding, the occiput rounding and a little elevated; eyes prominent, 

 somewhat longer than wide, separated above by a space about one- 

 half greater than the width of the frontal costa between the anten- 

 nae, the fastigium depressed, broadly and gently sulcate and provi- 

 ded with a few irregulär rugae within; frontal Costa prominent and 

 projecting anteriorly a trifle beyond the outer end of the first 

 antennal joint, coarsely punctate at sides, scarcely sulcate; cheeks 

 below the eyes very nearly as long as the greatest diameter of the 

 latter. Antennae slender, filiform, nearly as long as the hind femora. 

 Pronotum evenly лvidening posteriorly, without carinae, the posterior 

 lobe scarcely half the length of the anterior one, the last trans- 

 verse sulcus most pronounced; anterior edge very broadly rounded, 

 with the middle shallowly and rouudly excised, bind border broadly, 

 shallowly, and angulately emarginate above. Tegmina subhnear, 

 about five times as long as their greatest width, reaching across
