ish-blue ; the collar above, outer margin of the tegulae, a sutural line 

 before and a short line beneath the wings, and two longitudinal lines 

 on the disk of mesothorax, white ; scutellum same color as the meso- 

 thorax, sparsely punctured, polished, its lateral margins whitish ; post- 

 scutellum with a transverse white spot; metathorax finely and conflu- 

 ently punctured, the elevated lines tolerably well defined, the central 

 area moderate, subquadrate, indistinctly defined, smooth and shining. 

 Wings almost hyaline, being faintly tinged with fuscous ; nervures and 

 stigma black ; areolet 5-angular. Legs black, the anterior coxfe be- 

 neath, the four anterior femora at tip and their tibife in front, and 

 sometimes the posterior tibiae at base exteriorly, whitish. Abdomen 

 elongate, stout, brilliant deep blue, closely and finely punctured, shin- 

 ing ; basal segment rather broad, bilineated, finely aciculate, and with 

 a small whitish spot, sometimes obsolete or wanting, on each extreme 

 apical corner, the peduncle short ; extreme base of the second segment, 

 between the basal fovere which are deep, is coarsely aciculate ; apical 

 segments polished, impunctured. Length 6 — 8 lines; expanse of wings

This is a very beautiful species ; it agrees in some respects with the 

 description given of Icli. pulcher Brulle, but I cannot satisfy myself of 

 their identity. In this species the scape of the antennae is always 

 black, the face is black with narrow white orbits, and the sides of the 

 mesothorax and surface of the metathorax are not ornamented with 

 yellow lines or spots, as is said to be present in pulcher. I have not 

 seen the male. 



26. Ich. Azotus, n. sp. 



Black ; face, orbits, lateral lines of mesothorax and two lines on its disk, 

 scutellum, and apex of the first abdominal segment, white ; wings hyaline ; 

 central area of metathorax moderate, transverse. 



Male.. — Black, shining; the face beneath the antennae, orbits, cly- 

 peus, mandibles except base, and the palpi, white ; antennae porrect, 

 about three-fourths the length of the body, black, the basal joint be- 

 neath white. Thorax finely and closely punctured, with an impressed 

 line on each side of the mesothorax in front; the tegulaa, a broad sutu- 

 ral line before and a short line beneath the wings, and two short lines 

 on the disk above, white; scutellum rather flat, polished, white except
