PARACLIUS species 



Six females were taken by J. M, Aldrich in Guatemala; these 

 probably represent three species, but I have not been able to deter- 

 mine them. 



PARACLIUS ANGUSTIPENNIS, new species 



Fetnale. — Length 2 mm. Face narrow, white; front dull with 

 brownish pollen; antennae wholly black, third joint small, somewhat 

 rounded, irregular on apical margin ; arista short, pubescent ; lateral 

 and inferior orbital cilia white. 



Thorax and abdomen green, quite shining. Coxae, femora, pos- 

 terior tibiae and all tarsi wholly black; trochanters and fore and 

 middle tibiae yellow; all femora with a row of black hairs below, 

 which are longer than the hairs on upper edge; joints of fore tarsi as 

 18-9-7-5-6; of middle ones as 29-20-17-12-9; joints of posterior tarsi 

 as 22-31-20-7-8. Calypters and halteres yeUow, the former with 

 black cilia. 



Wings uniformly tinged with brown, rather narrow; third vein 

 straight ; last section of fourth vein with a broad, gradual bend near 

 its middle, arched beyond this bend so as to approach third vein and 

 run parallel with it for a short distance at tip, reaching the wing 

 margin a considerable distance before the apex of the wing ; last sec- 

 tion of fifth vein 23, cross vein seven-fiftieths of a millimeter long. 



Described from one female taken by J. M. Aldrich, April 14, 1926, 

 at La Providencia, Obispo, Guatemala. 



Ty^e.— Female, Cat. No. 41053, U.S.N.M. 



PARACLIUS ALBITALUS, new species 



Male. — Length 3.6 mm. Face silvery white, narrow above, wider 

 below, the portion below the suture almost round and a little concave ; 

 front shining blue or violet; antennae j^ellow, third joint brown at 

 tip, nearly round with a small point at tip ; lateral and inferior cilia 

 and the bristles below the head yellowish, a few of the upper cilia 

 black.

 pollen when viewed from in front; pleurae more black with white 

 pollen; there is no velvety black spot above the root of the wing. 

 Abdomen green, upper part of dorsum more blue, the spots of white 

 pollen on the sides of the segments conspicuous. Hypopygium and 

 its lamellae black, the latter yellow at base, with apical part rounded, 

 tapering abruptly at base into a yellow petiole, fringed with pale 

 hairs.
