Epicampocera. 511 



vertical and two orbital bristles. Frontal bristles not reaching to the 

 end of second antennal joint, two upper reclinate, in female distinct, 

 in male less distinct or all crossing. Fine but long postocellar and 

 occipital bristles. Behind postocular bristles a row of black hairs. 

 Cheeks hairy. Vibrissæ a little ascending, about to one third of the 

 height. Eyes bairy. Epistoma retreating, slightly reflected below. 

 Antennæ inserted a little above middle of the eye, third joint about 

 twice as long as second; arista with second joint a little elongated. 

 Thorax quadratic; three postsutural dorsocentrals and two præ- and 

 three postsutural acrostichals; a præsutural intraalar bristle. Scu- 

 tellum with four marginal bristles on each side, the apical the smaller, 

 crossing. Three sternopleural bristles. Pteropleura with a tuft of 

 small bristles above. Abdomen conically ovate; excavation on second 

 segment reaching hind margin. Sternites not concealed; there are 

 discai and marginal bristles, on second segment a pair of marginal. 

 Genitalia small, hidden under the venter. Legs with tarsi somewhat 

 long; hind tibiæ with anterodorsal bristles unequal; claws and pul- 

 villi in male elongated; front tarsi in female simple. Wings with 

 first posterior cell open, ending a little before apex of wing; discai 

 angle obtuse, apical cross- vein straight, sloping; no costal spine. 



The species are parasitic on Rhopalocera and Heterocera. 



About five European species are known; they are divided into 

 several subgenera after the shape of the antennæ, the presence or 

 want of discai bristles, and the hairiness on cheeks being fme or 

 robust. In Denmark only one species, conspersa, is known, belonging 

 to the subgenus Megalochaeta B. B.; the above description only refers 

 to this subgenus.
