This species attracted notice on account of its frequenting spider 
webs at Cabin John, Md. 
Clinodiplosis examinis Felt

Midges belonging to this species were present by hundreds if not 
thousands upon a screen door or hanging from cobwebs attached 
thereto at Nassau, June 19, 1913 and may possibly prey upon plant 
lice.

This genus was originally erected by Ritbsaamen for the reception 
of certain adults reared from mycophagous larvae, the type being 
Diplosis coniophaga Winn. It may be recognized by 
the regular whorls of hairs and the unidentate claws on the anterior 
and occasionally on the mid pair of legs, those of the posterior legs 
being simple. The genitalia are not greatly enlarged and the ovi- 
positor not remarkable for any peculiar structure. Examples of a 
species of Mycodiplosis received from Rtbsaamen and reared by 
him from Senecio, have the anterior claws unidentate, the mid and 
posterior pair simple. The terminal clasp segment in the male is 
long, slender, the dorsal plate deeply and triangularly incised and 
the lobes broadly rounded apically. 
The genus comprises a large number of small, yellowish or light 
brown forms presenting very much the same general appearance
