28 INSECUTOR INSCITI^ MENSTRUUS 



Width: pronotum, through the middle at lower border of the 

 lateral lobes, by caliper measure, 6 mm. ; posterior femora at 

 widest point, 2.75 mm. ; ovipositor, at middle, 2 mm.

In these specimens the dorsal teeth of the middle tibiae are 

 practically absent, being reduced to mere blunt tubercles. The 

 subgenital plate (PI. H', fig. 16), has an angulation on each 

 side of the notched apex. These were evidently obscured in 

 Brunner's type, as he makes no mention of them in his descrip- 

 tion. Aside from this plate the structure of these specimens 

 fits his description very exactly. One of these specimens, the 

 one taken in December, varies from the typical by having some 

 blackish coloration in some of the cells on the tegmina. 



The posterior tarsi of this species have the second segment 

 modified above somewhat after the manner of Saga as illus- 

 trated in my paper on the Saginse in Fascicule 167, Wytsman's 

 Genera Insectorum, p. 3, pi. ii, fig. 2 (1916).

This is a medium-sized species showing relationship to sev- 

 eral described forms but apparently referable to none of them. 

 In Brunner's key it runs out to variabilis but it does not seem 

 to i)ossess all the characters of that species. It is also appar- 

 ently related somewhat to infumatus Brunner but seems amply 

 distinct from that species. 



Description ( S, the $ unknown). — Plead smooth, of sub- 

 equal width with the front of the pronotum ; eyes round and 

 very prominent ; fastigium of the vertex small, triangular, 

 apically slightly notched, above broadly sulcate, the width less 

 than half that of the basal segment of the antennae and the 

 length but little greater than the basal width, not surpassing the 

 antennal scrobae, a round tubercle on each side at the base; 

 scutellum of the face abruptly tapering above to a rounded
