460 SUPPLEMENT. 
Tegule brownish-yellow. Wings brownish, the colour deeper towards the base ; small cross-vein on the 
middle of the discal cell; apical cross-vein concave near its base; posterior cross-vein slightly curved. 
Hab. Mexico !, Xucumanatlan, Omilteme, and Sierra de las Aguas Escondidas in 
Guerrero 7000 to 9500 feet (H. H. Smith). 
A long series of specimens of both sexes. This species much resembles Jurinia 
dichroma, differing, however, in the more elongate palpi, which reach as far as the tips 
of the vibrissee, this character bringing the insect into the genus Deeania. It seems 
to be very nearly related to D. armata, Wiedem. (Aussereur. zweifl. Ins. 1. p. 287), 
from Cuba, and to D. analis, Macq. (Diptéres Exot. ii. 3, p. 34), from Mexico. 
In both these species the abdomen is likewise rufous, with the anal segment black, 
but the legs are for the greater part rufous, and in D. analis the palpi are black. 
'‘D. brasiliensis, Rob.-Desv. (Essai sur les Myod. p. 33), seems to be yet another 
allied form. 
HYSTRICIA (p. 11). 
1 (a). Hystricia testaceiventris. 
Hystricia testaceiventris, v. d. Wulp, Tijdschr. voor Ent. xxxv. p. 190°. 
Thorax blackish ; scutellum and abdomen yellowish; head whitish; antenna, palpi, and legs black; third 
joint of the antenne twice as long as the second; wings infuscated. 
Length 13°5 millim. 
Face and cheeks greyish-white; the face inferiorly prominent; front blackish, narrowed behind and there 
narrower than the eyes; frontal band dark brown; frontal bristles in part stout, four or five of them descend- 
ing beneath the root of the antenne; beard white. Antenne black, with grey reflections; second joint 
with a long and several shorter bristles ; third joint rather narrow, twice as long as the second; arista 
indistinctly jointed, thickened to beyond the middle. Proboscis shining black; palpi black, slightly 
thickened towards the tip and with black bristly hairs. Thorax black, with some bluish reflection ; 
thoracic dorsum before the transverse suture with some grey tomentum and indistinct black lines ; 
scutellum yellowish-rufous, with black spines. Abdomen cordiform, broader than the thorax, yellowish- 
testaceous, somewhat transparent; second and third segments with an interrupted black dorsal stripe 
and densely beset with black spines; anal segment black, with numerous black hairs and spines. Legs 
with many bristles, those on the outside of the middle tibia longer; foot-claws and pulvilli rather 
elongate, yellowish, the claws with black tips. Tegule brownish-yellow. Wings brownish; small 
cross-vein on the middle of the discal cell; apical cross-vein concave at its base; posterior cross-vein 
distinctly curved and inserted on three fourths of the apical cell. 
Hab. Mexico!, Xucumanatlan in Guerrero 7000 feet (A. H. Smith). 
A single male specimen. This species must be placed immediately after H. albiceps, 
vy. d. Wulp, with which it agrees in the black colour of the antenne, palpi, and legs, 
but differs from that insect in the yellowish coloration of the scutellum and abdomen. 
Hystricia infuscata (p. 12). 
There is a female of this species from Mexico in the collection of Professor Bellardi. 
It agrees with the one described by me (anted, p. 12), but the coloration is less obscure, 
the third antennal joint is rufous (like the basal one), and the wings have a darker 
rufous tint. |
