Ommatolampis corruganota, sp. u. 



A moderately slender, subcylindrical. subapterous, uniformly 

 olivaceous species \v\U\ unnsually long; antennae in which the trans- 

 verse sulci of the pronotum are remai'icably deep, thereby giving a 

 transversely coiTugated ajtpearance to this portion of its body, — 

 hence the name. Outer joint of pali)i only slightly but still quite 

 notieeably spatulate. 



Heail of moderate size, about as wide as the front edge of the 

 pronotum, the front a little oblique; eyes large, in the maie pro- 

 minent, separated above by a space equal to the frontal costa which 

 latter is fairly ])rominent and roundly produced between the anten- 

 nae, provided with a few coarse punctures and terminating at the 

 ocellus: the fastigium rather strongly depressed and shallowly sul- 

 cate and provided with a few low irregulär rugosities: antennae 

 quite slender and unnsually long, in the maie three-fourths the length 

 of the body and in the feniale nearly or quite as long as the bind 

 femora. Pi'onotum rather short, sul)cylin(lrieal and only a trifle 

 expanding jjosteriorly, the transverse sulci very profound and deep, 

 sei)arating this part of the body into four nearly equal transverse 

 folds, the next to the last of which prqjects as Shoulders beyond 

 the others and continues down the lateral lobes nearly to their 

 lower margins; anterior edge roundly advanced upon the occi- 

 ]»ut aiul emarginate at middle, bind margin shallowly, roundly 

 and very widely emarginate. the posterior lobe only about one- 

 fourth of the enth'e length. Entire thorax above, together with 

 the dorsum of the basai half of the abdomen, strongly and closely 

 punctate and giving to the insect's body a decidedly rugose appea- 

 rance, the punctures on the head and a]iical half of the abdomen 

 sparser and shallower. Apical portion of maie abdomen a very little 

 enlarged and u])turned; the last ventral segment short, bullate and 

 a little produced at middle; sujiraanal plate triangulär, the sides a 

 little upturned and the disk jirovided with about a half dozen black 

 rugosities; apex of preceding segment furnished with an equal 

 number of short, black teeth. Cerci heavy, short, conical, with an 

 inner fold on their basai half. Prosternai spine short, heav^ at 

 base, the apex slender and gently directed to the front. Posterior
