230 PROCEEDINGS OF THE ACADEMY OF [1897. 



pronotum rounded antero-laterally, posteriorly arcuate, in the middle 

 about as long as the scutellurn ; seen from the side, the dorsulum is 

 much natter than in tyrannicus and the middle segment is shorter, 

 the posterior surface not being emarginate but depressed or sub- 

 concave, the postero-lateral angles hardly prominent ; the upper sur- 

 face with a faint central, longitudinal furrow ; legs feebly spinose, 

 the inner spur of hind tibia? just about half as long as the first 

 hind tarsal joint; wings comparatively shorter than in tyrannicus, 

 blackish with a reddish-purple iridescence, second submarginal 

 rhomboidal ; abdomen compressed apically. Length 15-17 mm. 



Chapada (March, October). Two specimens. Has a superficial 

 resemblence to species of the genus Notogonia. 



Notocyphus abnormis Tasch. (=Ceropales dbnormia Tasch.). 



Six specimens, Chapada (March, September, November). They 

 vary from 13-17 mm. in length. 



Notocyphus terminatus n. sp. 



9 . — Black ; palpi testaceous ; seven last antennal joints orange ; 

 eyes not reaching mandibles; clypeus broadly truncate; labrum 

 narrowed apically, truncate, in length scarcely equal to width of 

 clypeus; space between eyes above about equal to length of second 

 and third antennal joints ; antennae stout, somewhat longer than 

 head and thorax ; pronotum posteriorly arcuate, having a tendency 

 to become angular ; middle segment long, strongly emarginate and 

 concave posteriorly, the postero-lateral angles produced and strongly 

 marked, on the sides a furrow orginatesat the stigma and terminates 

 in a broad pit at the hind coxse ; legs feebly spinose, the longer spur 

 of hind tibia? more than half as long as first hind tarsal joint ; wings 

 fuscous, faintly purple, pale at apex of anteriors, the extreme base 

 and a small spot at base of first discoidal cell, obscurely yellowish ; 

 cubital vein of hind wing originating distinctly before apex of sub- 

 median cell ; abdomen shorter than the thorax, scarcely compressed. 

 Length 18 mm. 



Chapada (March). One specimen. 



Notocyphus pictipennis n. sp. 



9. — Structurally, this species agrees exactly with terminatus; 

 also in the coloration of antennae. The wings, however, have the 

 basal two-thirds, bright yellow, the remaining third dark fuscous, 

 with the tips of anteriors pale. Length 18 mm. 



Chapada (April). One specimen. Will probably prove to be a 

 variety of terminatus.
