SAUNDERSIA.—JURINIA. 27 
The following species recorded from Central America are unknown to me:— 
Saundersia flavitarsis, Macq. Dipt. Exot. ii. 8, p. 47. 4, t. 5. f. 1; Suppl. 1. 
p. 152. 11, t. 18. f. 7, and iii. p. 45 (Micropalpus) ; Schin. Reise d. 
Novara, Zool. iii., Dipt. p. 334. 128.—Mexico ; South America. 
ornata, Macq. Dipt. Exot. ii. 3, p. 47. 5, t. 4. f. 6 (Micropalpus) ; 
Schin. Reise d. Novara, Zool. iii., Dipt. p. 333. 126.—Mexico ; 
Colombia. 
rufipes, Jaenn. Neue exot. Dipt. p. 79. 104 (Micropalpus).— Panama. 
N.B.—The name of this last species ought to be changed on account of the Brazilian 
Hystricia rufipes, Macq. (Dipt. Exot. suppl. iv. p. 172. 8); this latter has very short, 
hardly perceptible palpi, and therefore probably belongs to the genus Saundersia. 
JURINIA. 
Jurinia, Robineau-Desvoidy, Essai sur les Myodaires, p. 34 (1830). 
This genus is nearly allied to Dejeania, Hystricia, and Saundersia. In the shape 
and development of the palpi it closely approaches Hystricia, but differs from it by 
the eyes being bare. 
_ In the Central-American collection before me there are three species which I have 
attempted in vain to recognize from the existing descriptions; they are accordingly 
described as new and may be characterized as follows :— 
Abdomen yellow, with black extremity. . . . . . + « « dichroma, v. d. Wulp. 
Abdomen unicolorous, brownish-red. 
Palpi black; wings dark brown . . . - 1 ee es badiiventris, v. d. Wulp. 
Palpi fulvous; wings brownish-grey . . . . . . . . adusta, v.d. Wulp. 
1. Jurinia dichroma, sp.n., ¢ @. (Tab. II. figg. 5; 5a, head in profile.) 
Black, including the antenne and legs; head white; palpi ochraceous ; hind portion of the thorax, scutellum, 
and abdomen (except the base and the fourth segment, which are black) yellow; wings brownish. 
Length 12-5-14 millim. | 
Head white, sericeous; oral margin prominent; front narrowed behind, especially in the male; median band 
black or piceous; frontal bristles in the male descending on both sides in a double row to beneath the 
base of the antennzy, in the female in a single row, the outward row being represented only by a pair of 
strong bristles; cheeks with blackish pile; vibrisssee accompanied above as well as below by some shorter 
bristles; beard and hairs of the occiput pale yellow; immediately behind the eyes a row of short black 
bristles. Antenne black; second joint on the upper part bristly (in one of the female specimens rufous 
at the end); third joint ovate, as long as the second; arista rather distinctly jointed, gradually tapering 
towards the apex. Proboscis shining black; palpi pale ochraceous, thickened near the end. Thorax 
black, with some grey tomentum, and on the fore part indistinct black stripes, at the hind border and on 
both sides under the root of the wings brownish-yellow ; pilosity black; macrochetz moderately robust ; 
scutellum and abdomen leather-yellow, dull; scutellum with many bristles and spines; first abdominal 
segment black at the base; third segment at the hind margin with two dorsal and two lateral black spots ; 
fourth segment, except the front margin, black ; black spines are ranged in rows on the middle and at the 
hind margin of the second and third segments, and there are three lateral ones on the third segment, a 
great number on the entire surface of the fourth, and some also on the middle of the venter. Legs black ; 
bristles moderately long and, at least in the male, not very robust; pulvilli yellow ; claws rufous at the 
e2
