Black ; head pale yellow: antenne black or brown; frontal bristles descending irregularly beneath the root 
of the antenne ; palpi fulvous; abdomen densely spinose; wings brownish-grey.

Nearly allied to J. adusta. Antenne longer than in that species and of a darker coloration, mostly black, 
with the apical part of the second joint and a spot on the posterior part of the third reddish ; the bristles 
of the second joint longer and closer together; the third joint longer than the second. The abdomen is 
. darker, in the female black, its whole surface covered with spines, those at the hind margin of the 
segments longer. The foot-claws are yellow, with a black tip; the front tarsi not dilated in the female. 
- Hab. Mexico 1, Venta de Zopilote, Chilpancingo, Xucumanatlan, Omilteme, Atoyac, 
Teapa (H. H. Smith), N. Yucatan (Gaumer). 
Several specimens of each sex. 
9. Jurinia congruens. 
Jurinia congruens, v. d. Wulp, Tijdschr. voor Ent. xxxv. p. 192". 
Black; head pale ochraceous: antenne and palpi rufous; frontal bristles descending irregularly beneath the 
root of the antenne; spines of the second and third abdominal segments at the hind margin only. 
Length 11-13 millim. 
Allied to J. adusta and J. assimilis. The antenne are rufous, the third joint sometimes partly brown ; second 
‘joint as in J. assimilis ; third joint as long as the second. The abdomen is dark piceous(¢ )or black(@); 
the spines are less numerous than in J. adusta; the foot-claws yellow, with a black tip; the front tarsi 
not dilated in the female. 
Hab. Mexico!, N. Yucatan (Gaumer). 
«One male and two females. 
BELVOSIA (p. 29). 
Belvosia bifasciata (p. 30). 
To the localities given, add: —Mexico, Guadalajara (Schumann), Chilpancingo, Amula 
(H. H. Smith). 
Specimens of both sexes have been received from Mexico. [This species and 
B. bicincta, R.-Desv., are recorded by Mr. Townsend [Ann. & Mag. Nat. Hist. (6) xix. 
p. 33 (1897)] from San Rafael, Vera Cruz.—Eb. | 
Belvosia leucophrys (p. 30). 
_To the localities given, add :—Mexico, Chilpancingo, Amula, Omilteme, Cuernavaca, 
Atoyac, Teapa (/. H. Smith). 
Many specimens of this species have been sent from Mexico, as well as others (from 
Orizaba, Atoyac, and N. Yucatan) of what I take to be a variety of it. In these latter 
the spines on the scutellum and abdomen are almost entirely absent, the abdomen being 
thickly covered instead with short black hairs, which give it a velvety appearance.
