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 

 mafgin ; 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, mehan 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 lengtii of the tibia; em- 

 podium filiform, sparsely plumose, pulvilli brushlike. Wings hyaline 

 not punctate (under amplificatiou 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 scrdidellus 



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 Bui. 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

Metriocnemus exagitans Johannsen 



Li 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 Bui. 86. I have seen s")-"-:'mens of this species from 



New A^ork, Kansas, and Colorado.
