ARNILIA Stal. 

 ARNILIA CYLINDRODES Stal. 



Opsnmala cyUndrodes StIl, Freg. Eugene Resa, Ins. Orthopt., 1860, p. 825.-

This insect was described originall}^ as coming from Rio Janeiro, 

 Brazil, by its author, and later b}- himself credited to North Carolina 

 as well. Not having- specimens of the genus from Rio Janeiro or other 

 Brazilian localities that agree with StaPs description, it has not been 

 recognized by me. I am inclined, however, to consider the North 

 Carolina insect as distinct from the Brazilian. 



Giglio-Tos credits cyli/idrodes to Paraguay. 



ARNILIA GRACILIS Giglio-Tos. 



Two males of a slender Arnilia, which the writer collected in 1897 

 at San Bernardino, Paraguay are referred here. 



ARNILIA COCCINEIPES, new species. 



Related to Arnilia viridis Serville, but a trifle larger and differing 

 from it in several other respects. General color pale green above, 

 without the lateral white lines of viridif< and other related species of the 

 genus. Antennge ferruginous. The dorsum of abdomen also lacks 

 the red of viridis, while in the present insect the entire hind tibiae are 

 red, instead, of merely the base and apex. 



Insect more or less distinctly hirsute throughout, but not prof usel}^ 

 so except on lower side of abdomen near its apex. Form cylindrical, 

 slender, the tegmina and wings extending considerably beyond the 

 tip of the abdomen; the former acuminate, rather closely veined on 

 basal half, less so on apical half. Head smooth, the occiput as long 

 as the anterior lobe of the pronotum, the eyes rather large and mod- 

 erately prominent, very little more pointed above than below, much 

 longer (nearly twice the length) than the cheeks below them; face 

 strongly oblique; vertex rather broad, nearly (male) or quite as wide as 

 the frontal costa in its broadest part (female) ; the f astigium fairly prom- 

 inent, a little wider than long, and with the anterior angle somewhat 

 rounded, the margin a trifle elevated; frontal costa prominent above 

 where it is considerably expanded between the base of the antennae; 

 below this with the sides parallel, deeply sulcate throughout. Prono- 

 tum C3'lindrical, rather shallowl}^ but profuseh^ punctate; the median 

 carina visible only on the posterior lobe; ttanverse sulci well defined, 

 the last situated back of the middle; front edge subtruncate, hind 

 edge broadly rounded. Meso- and metapleura closely punctate, pectus 

 smooth. Hind femora moderately robust, shorter than the abdomen 

 in both sexes. Hind tibiae with 7 spines in outer row. Prosternum 

 robust, the apex truncate, rather larger than at base. Last ventral seg-
