INSECUTOR INSCITI^ MENSTRUUS 63 



Anaulacomera simplex, new species. (PI. II, fig. 23.) 



This apparently undescribed form is most nearly allied to A. 

 erinifolia Brunner but is separable at a glance from that species 

 by the smaller size and by the absence of black maculation in 

 the anterior tibiae. It also shows close relationship to A. boliv- 

 iana Brunner but its size and the more distinctly carinate front 

 separates it from that Bolivian form. 



Description ( $ , the 9 unknown). — Head with the sides of 

 the front longitudinally and broadly depressed, the margins 

 somewhat abrupt, tending to make the front laterally carinate ; 

 fastigium of the vertex very narrow, much less than half as 

 wide as one of the basal segments of the antennae, tapering to 

 a narrow rounded tip, above distinctly but not deeply sulcata. 

 Lateral lobes of the pronotum about as high as long and 

 rounded into the disk without distinct lateral carinse except on 

 the metazona. Anterior and intermediate tibiae with a small 

 dorsal spine on the caudal margin and the intermediate ones 

 with three additional ones. Abdomen with the last dorsal seg- 

 ment apically truncate ; supraanal plate deflexed, apparently tri- 

 angular ; subgenital plate longer than broad, narrowing apically 

 and with the tip notched, each angle prolonged as a very short 

 unsegmented style ; cerci short, simple, incurved, tapering grad- 

 ually to a moderately sharp and somewhat abruptly curved 

 point as shown in Plate II, figure 23. 



Color yellowish green, the elytra with a few dusky spots and 

 the entire insect, body, legs, and antennae, sprinkled with red- 

 dish dots so small as to be scarcely visible to the unaided eye. 



Measurements. — Length : pronotum, 4 mm. ; tegmina, 25 

 mm.; posterior femora, 15 mm.; cerci, 2.5 mm.; width: teg- 

 mina mesially, 4 mm.
