Trichoparia. 445 



times arranged in a single row, Vibrissæ ascending more or less above 

 the middle to quite up. Eyes bare. Palpi small. Antennæ as in Ad- 

 montia; arista with second joint short or somewhat elongate. Scu- 

 tellum with three marginal bristles on each side, apical hairs wanting 

 or very small. Claws and pulvilli in male not elongated, or very small; 

 front tarsi in female with the foiir last joints only very slightly dilated, 

 or more dilated, as in Admontia. Wings with discai angle obtuse; 

 costal spine wanting or very small. 



Two of the species have been bred from Tipulids. 



The genus contains 4 species; 3 occur in Denmark. 



Table of Species. 



1. Thorax with two broad black stripes 1. hlanda. 



— Thorax with four black stripes, two narrow median and two 

 broader lateral 2. 



2. Arista with second joint somewhat elongated; base of wing 

 and squamulæ rather yellow; middle tibiæ with two long 

 anterodorsal bristles; claws and pulvilli as long as fifth tarsal 



joint; front tarsi in female dilated 2. seria. 



— Arista with second joint short; base of wing and squamulæ 

 not specially yellow; middle tibiæ with one anterodorsal 

 bristle; claws and pulvilli quite small; front tarsi in female 



very slightly dilated 3. decorata. 



I have followed Stein in placing hlanda in this genus and not 

 in Admontia because of the wanting apical bristles on scutellum; 

 both genera might, as also Stein remarks, well be united, the dividing 

 characters, I think, scarcely being satisfactory.
