A REVISION OF THE GENUS LEPTOCONOPS, SKUSE. 21 



Subgenus Holoconops, Kieff. 



Holoconops, Kieff., Ann. Mus. Nat. Hung, xvi, p. 135 (1918). 



This subgenus comprises those species of Leptoconops {sens, hit.) in which the 

 antennae of the female are composed of thirteen segments ; in all the known species 

 the claws in this sex are simple and equal. The group was given generic rank by Kieffer, 

 who based its separation upon the structure of the female antennae and claws. Such a 

 combination of characters, however, cannot be maintained, since the structure of the 

 claws is in no way pechliar, and this author's restriction of the type mentioned above 

 to Holoconops is evidently due to a misconception. Kieffer designated L. kerteszi, 

 Kieff., as his genotype, and, in a footnote, a.ssociated it with L. flaviventris, Kieff., 

 L. hyahnipennis, Kieff. (synonymous with L. bezzii, Noe), and L. ladeipennis, Kieff. ; 

 but the inclusion in this group of the second and third-named species is a palpable 

 oversight, as in his descriptions of them on preceding pages of the same article the 

 antennae are definitely stated to possess the full complement of segments (fourteen). 



Three species of this subgenus are here recognised, but one {L. interruptus, End.) 

 is insufficiently described, and may subsequently prove identical with one of the 

 others. They are widely distributed, and have been recorded from Northern Africa, 

 Asia Minor, South West Africa and the United States of America.

The synonymy given above is based upon examinations of specimens sent me as 

 L. kerteszi by Mr. F. C. Willcocks from Egypt, and of females of L. lanrae sent me by 

 M. A. Weiss from Tunis. L. kerteszi was described by Kieffer from specimens collected 

 at Cairo, and the material received from Mr. Willcocks agrees in detail with this 

 author's descriptions. Furthermore Kieffer, who is evidently unacquainted with 

 L. lanrae, has recently (1918) recorded L. kerteszi from Tunis. 



The following description is compiled from the Egyptian and Tunisian specimens 

 referred to above. 



?. — Length of body (six specimens), 1 •8-2-1 mm. ; length of wing, 1 • 1-1 -3 mm. ; 

 length of antenna, 0-33-0 -42 mm. ; width of head, 0-31-0-34 mm. 



Head shining black, the antennal depressions pale buff, sparsely clothed on the 

 vertex and occiput with short black hairs ; clypeus shining black, with three pairs of 

 dark hairs ; eyes relatively widely separated, the space between them being approxi- 

 mately two-fifths the width of the head. Proboscis dark brown or black. Palpi 

 {cf. fig. 2, d) dark brown, with brown hairs ; third segment very strongly swollen, 

 with a large oval pore situated near the middle, fourth segment slightly inflated 

 distally, scarcely shorter than the third. Antennae {cf. fig. 5, g) dark brown, with 

 rather long (about twice the length of the segment) pale brown hairs ; fourth to twelfth 

 segments transversely oval to spherical, from 0-8 to 1 -0 as long as broad ; thirteenth 

 segment equal in length to the preceding three and one-third to four segments together. 

 Thorax entirely shining black, with short black hairs ; scutellum with two pairs of 

 bristles. Wings white, iridescent ; venation normal, the anterior veins not quite 

 reaching the middle of the anterior border and arranged as in fig. 8, h ; fifth vein 

 bifurcating slightly before the extremities of the costa and third veins. Halteres 

 whitish. Legs dark brown, clothed with dark hairs ; metatarsi of the hind legs paler 

 brown, with short brownish yellow hairs ; fore and middle metatarsi with a basal and 

 apical pair of slender, pointed spines, and a few (one to four) central, usually unpaired,
