Trichocladius politus Coquillett? 
Some male and. female specimens which may be the above species, 
agreeing with Mr Coquillett’s description, possess also the following 
characteristics. Eyes hairy, collar not incised on the dorso-anterior 
margin; abdomen black with a greenish tinge, venter more greenish. 
Costa produced beyond the tip of R,,, over half the length of the 
cross vein. Pennsylvania. 
Psectrocladius aureus n. sp. 
Female. Head and mouth parts fuscous, proboscis black, eyes 
bare, palpi much longer than the antennae, basal joint short, second 
and third stout, apical joint slender; antennae dusky. Collar deeply 
incised on dorso-anterior margin, each side of incision with tooth- 
like projection;: thorax dusky yellow, median stripe wide, black; 
laterals narrow, brown; metanotum and pleura brown, scutellum 
yellow. Abdomen wholly golden yellow. Legs yellow, tarsal joints 
slightly darker ; foremetatarsus about .9 the lengin of the tibia; em- 
podium filiform, sparsely plumose, pulvilli brushlike. Wings hyaline 
not punctate (under amplification of 75 diameters); costa very 
slightly produced beyond the radius, cubitus forks slightly beyond 
the cross vein. Halteres pale yellow. Length 2.5 mm. Kansas. 
Orthocladius sordidellus 
The species from North America under this name are probably 
not this species at all, as may be seen by comparing the description 
of the early stages given by me in Bul. 86 with that of Thienemann 
(1906). There seem to be several closely allied species which differ 
but slightly. To properly describe and distinguish these would 
require more material than I have at present at my disposal. 
Genus METRIOCNEMUS 
Van der Wulp, 1874. Synonym Wulpiella Kieffer 
Metriccnemus exagitans Johannsen 
In this species the vein R,,, ends some distance from the tip of 
the wing and not “ nearly to the tip of the wing” as stated in the 
description in Bul. 86. I have seen soecimens of this species from 
New York, Kansas, and Colorado. 
Metriocnemus par Johannsen 
A female specimen from New Jersey has large abdominal spots 
and dusky thoracic stripes. Some female specimens from Old
