only a single male of kahli and two males of coniutus were taken. Moreover 

 the last two species were not taken elsewhere at Villa Murtinho. 



Specimens of both sexes of solutus may be specifically recognized at once 

 by the free, outwardly directed inferior end of the mesostigmal lamina, 

 the character to which the specific name refers. 



9. Perilestes minor, new species 



Abdomen male 40-41; hind wing male 20; stigma front wing male 1.10- 

 1.20; stigma hind wing male 1.20-1.30; abdominal appendage male 1.2D; 

 male anterior lamina from apex of sternum of segment 1 to apex of the 

 posterior process 1.30. 



Male. — Labium as in solutus ; labrum black, narrowly blue across the base, 

 this blue indented at the middle with a rounded backward projection of 

 the black; anterior surface of the clypeus bright blue, the dorsal surface 

 black, the line separating the two colors smooth. 



Prothorax similar to that of solutus, but the proepimeron pale like the 

 adjacent parts. 



Thorax similar to that of solutus, the dorsal black wider, and with the 

 lateral margins convex rather than straight as in solutus, above adjacent 

 to the antealar sinus fading out to brown; the pale color on the mesepi- 

 sternum, adjacent to the humeral suture, is reduced to about half the width 

 or less of the corresponding pale area in solutus, and is scarcely .3 wide; 

 side of thorax similar to that of solutus, but the black superior spot on 

 the humeral suture is less marked in minor, and the spot posterior to this 

 spot in solutus is wanting in minor. Beneath similar to solutus but the 

 dark line on the metasternum reduced to an anterior black spot and a pos- 

 terior brown spot. 



Mesostigmal lamina nearly straight above, the lower end an acute nearly 

 right-angled angle, this angle the homologue of the projecting point which 

 characterizes solutus. 



Coxae pale. Femora pale, extensively dark marked as follows : largely 

 black beneath, reduced toward the base, apically extending more or less 

 onto the anterior surface, dorsal surface with base and apex dark shaded and 

 with two transverse brown bands, the five bands of light and dark between 

 base and apex thus formed are subequal in extent; this pattern present 

 but not as well marked on the first femur. Tibiae pale yellowish, black 

 beneath on the first tibia along the comb. 



Venation similar to that of solutus ; stigma brown to black, no trace 

 of the reddish brown which is well marked in that of solutus. 



Abdomen seen from above : 1 pale brown, obscure and scarcely darker 

 than the pale sides, this brown interrupting the apical black ring in the 

 midline ; 2 brown, slightly or scarcely darker at base and more distinctly 

 so at apex, the two darker areas and the included paler area about equal 

 in extent; 3-6 each with a narrow transverse basal pale blue ring, followed 

 by brown which passes subapically into a narrow pale ring which is suc- 

 ceeded by the two or three times more extensive apical black ; the extensive 

 brown area of each segment is darker, progressively from 3-6, until on
