624 Prof. Mario Bezzi’s Report on a Collection of 
all 
Hyalanthrax by Osten-Sacken in 1887, and Aspiloptera by 
Kiinckel d’Herculais in 1905. 
The collection has the three following species :— 
1(2). Face with black and yellow hairs intermingled ; abdomen 
with scaly hairs on the sides, and a black tuft towards the 
middle ; end of the abdomen with white tufts; tibiae 
black . : 5 . paniscoides, sp. n. 
2 (1). Face without black Hee ehdemen without black tuft on the 
middle of the sides ae without white tufts at the end ; 
tibiae yellowish. 
3 (4). Abdomen with black tufts on the sides before the end 
Jlavescens, Loew. 
4 (3). Abdomen without black tufts before the end . albescens, Loew, 
31. Villa paniscoides, sp. nov. 
36 2. Length (of 3 specimens), 11-13 mm. 
Near paniscus, Rossi, but very distinct on account of the black 
hairs on the face, and the lateral tufts of black scaly hairs on the 
third abdominal segment. A. dizona, Loew (1860), seems to be an 
allied species, 
Frons black, that of the male very narrowed, clothed with black 
hairs, yellow hairs being present only upon the antennae, more 
abundant in the female ; face with yellow hairs, but with many 
black hairs intermingled, chiefly towards the middle. Antennae 
black, very short, the terminal style longer than the whole antenna ; 
the two basal joints bear black hairs, which in the male forma very 
dense fringe. Thorax clothed with yellow-grey hairs, which in 
front are very long and dense, and in the middle and hind portion 
are shorter and darker ; pleurae with dense whitish hairs and a very 
thick tuft of white hypopleural hairs. Squamulae fuscous, with 
silvery white fringe. Halteres yellowish-white. Abdomen black, 
clothed with long grey hairs, which towards the middle are very 
dark; in the male there are indistinct transverse bands; the 
sides of the first segment with dense white hairs; on each side of the 
third segment is a large tuft of black scaly hairs ; fourth with whitish 
tuft, fifth and sixth with scaly black hairs; at the end a white tuft 
on each side, as in paniscws. Underside black, with greyish hairs. 
Legs wholly black, with black bristles and scattered yellowish scales. 
Wings hyaline, narrowly yellowish at the base, with black veins ; 
basal comb well developed, in the male black with silvery scales at 
the base, in the female yellowish with yellow scales ; second vein 
not strongly bent at the end ; discal cell very long ; rather narrow, 
the small cross-vein placed before its middle.
