the clypeus, and by the absence of them from the metanotum from 

 Sabethinus. 



Lesticocampa lunata in its whole appearance comes very close to the 

 present form, but separates at once by the small, narrow, curved, thoracic 

 scales of lunata ; moreover, lunata is a much larger species. No Den- 

 dromyia description, either of Theobald or of Lutz, agrees with my spe- 

 cies, and thus I can not but take it to be a new one. 



Culex prasinopleurus, new species. 



Female. — Proboscis 1.75 mm. (1.2 the standard), bent up dorsally 

 in my (dried) specimens ; gradually swelling toward tip, rather stout, with 

 short dark hairs ; clothed with flat black scales above, ventrally on ante- 

 rior third and at base and whitish in the middle ; labellae ovate, lighter 

 brownish at tip, with whitish pubescence. Palpi almost 0.3 mm., one- 

 sixth the length of proboscis (in side view), black-scaled, with some out- 

 standing hairs. Antenn2e longer than proboscis, about 1 .9 mm., or 1 .3 

 the standard ; tori black ; joints about four times as long as wide, rugose, 

 dark gray, with fine white basal rings, with shining white pubescence emd 

 black hair-whorls. Eyes black, shining coppery. Face black. Clypeus 

 black. Occiput black with dark bronzy lighter shining small narrow 

 curved scales, which are especially light, almost pure white, around the 

 eyes, numerous black upright forked scales present ; black light shining 

 hzurs most numerous on the sides and at the border of the eyes, the peiir 

 at vertex distinctly coarser but separated from the other hairs by only a 

 small distance ; sides of head with few white flat scales ; neck testaceous. 



Prothoracic lobes rather large, black, sublateral, with numerous coarse 

 black bristles. Mesonotum 1 .4 mm., chestnut brovm ; vestiture of black, 

 shining bronzy, minute hairlike scales, two median lines smooth ; prescu- 

 tellar pit only partly nude ; long black coarse bristles forming three rows 

 on disk, one median double line and a pair of rows which are simple 

 throughout ; numerous bristles at the latereil and anterior edges of disk, 

 especially above and before the basis of wings. Scutellum lighter ochra- 

 ceous gray, with scales like those on mesonotum ; seven long bristles on 

 median lobe, four long ones on each side lobe as well as smaller ones. 

 Postnotum nude, ochraceous, darker in the middle. General impres- 

 sion of the sides and ventral parts dull whitish, with a greenish to ochra- 

 ceous shade. Under the microscope pleurae and coxae ochraceous, the 

 most prominent parts darkened, shining greenish white in certain lights ;
