and numerous, those on the outside at apex of hind coxæ form a curious 

 fan, and below the middle trochanters is a long, oiitwards pointing 

 bristle; the front tibiæ have no bristles, the middle tibiæ have one 

 or two anterior bristles above the middle and one at apex, and the 

 hind tibiæ have likewise one or two bristles on the anterior side above 

 the middle and one at apex; these bristles are present in both sexes 

 and constant (single individual aberrations not considered), but 

 further the middle tibiæ have dorsal bristles, characteristic of the genus ; 

 these bristles may, all species taken in consideration, be present in 

 a number from one to nine, but the number varies both for the various 

 species and individually, and is always larger in the male than in 

 the female; in the males the number may in the various species be 

 in all from three to nine and in the females from one to four, but 

 in the single species the number varies less, generally from one to 

 three; the number is often diiferent on right and left tibia. The bristles 

 are long and strong; the posterior tibiæ have longer and shorter apical 

 spurs. For the rest the legs are clothed with short hairs, as usual a 

 little longer on the dorsal side of middle tibiæ in the apical part, 

 and arranged in comb-like transverse rows on the posterior side of 

 hind tibiæ in the apical part and on posteroventral side of hind 

 metatarsi. Claws and pulvilli small; empodium bristle-shaped. Wings 

 with the thick veins rather strong and costa reaching near to, or more 

 or less to considerably beyond the middle; costal cilia long or moder- 

 ate; the first vein runs parallel with the costa and suddenly curves 

 up at the end, the mediastinal vein is distinct and well developed, 

 stretching near to the curve of the first vein; third vein not forked; 

 the seventh vein is very weak or only visible as a fold, it goes generally 

 to the margin, but is sometimes a little abbreviated; also the anal 

 vein is indicated as a concave fold and more or less visible, either 

 only in the basal part or stretching to the middle, the extreme base 

 of it is fully developed; at the base of third vein there is a strong 

 bristle. 



The developmental stages are, so far as I am aware, not described; 

 the pupa of a species, considered as aterrima, is mentioned by Mégnin 

 (Compt. rend. de l'Acad. des Se. 105, 1887, 948, and La fauna des 

 cadavres, Paris 1894); the author found the pupæ and puparia in 

 great numbers on exhumed human bodies which had been buried 

 two to three years ago; he thinks that the eggs are deposited on the 

 ground so that the young larva penetrates down to the body; this 

 is possible, but I should be inclined to think that the eggs have been
