202 PROF. M. BEZZI. 



2. Lonchaea (Lamprolonchaea) aurea, Macq. 



Of this interesting species I have seen in the Museum of Genoa specimens taken 

 at S. Nicolas and S. lago, Cape Verde Islands, in May and November 1898, by the 

 late L. Fea ; and in the Cape Museum specimens from the Transvaal. 



3. Lonchaea (Lonchaea) continentalis, sp. nov. 



Very closely allied to lambiana, Bezzi {longicornis, Lamb), from the Seychelles, 

 and perhaps only a continental form of it, but seeming to diff 3r in having the tarsi 

 more broadly yellow at base, and in the wings not being brownish. 



(J. Length of the body, 3-3*2 mm. ; of the wing, 3*l-3*3 mm. 



Head and its appendages entirely black ; frons proportionally narrow, opaque, 

 with shining vertical plates ; lunula below white, shining ; face quite flat and clothed 

 with whitish dust, which is more shining at sides ; antennae with the third joint 

 extended to the mouth-border and with long, black, microscopically pubescent 

 arista ; palpi broad, with some bristly hairs. Chaetotaxy normal. Thorax and 

 scutellum shining black, not dusted at all, with bluish reflexions on the back ; chaeto- 

 taxy normal ; mesopleurae with bristly hairs on the middle, 2-3 bristles curved 

 backwards at hind border, and 2 bristles curved forwards at anterior border ; 

 sternopleurae with only one strong bristle ; scutellum with some hairs at border 

 between the usual bristles, Squamulae white and white-fringed ; halteres black. 

 Abdomen shining black and black-haired ; it has no special ciliation at the tip, nor 

 prominent genitalia ; the last segment is simple and only a little longer than the 

 preceding one. Legs black, with tho two basal joints of all the tarsi yellow. Wings 

 hyaline, slightly greyish on the fore half ; second longitudinal vein quite straight ; 

 terminal portions of the 3rd and 4th veins parallel ; small cross- vein a little before 

 the middle ol the discoidal cell ; the spurious continuation of the 6th vein is only 

 faintly indicated ; second costal cell with normal dilatation. 



Type (J and an additional specimen of the same sex (British Museum) from Natal, 

 Durban, 28. ix. 1916 (C. P. v.d. Merwe) : another male specimen in the writer's 

 collection from Erythraea, Ghinda, viii. 1916 {Dr. A. Mochi). 



4. Lonchaea (Lonchaea) impressifrons, sp. nov. 



Very similar to the preceding species, but of a more glistening bluish colour, with 

 partly reddish antennae and with crystalline wings. 



5. Length of the body, 2*6 mm. ; of the wing, 2*8 mm. 



Frons rather narrow for a female, opaque, with shining ocellar and vertical plates ; 

 before the ocelli there is a distinct ovate depression ; lunula shining white ; face 

 rather shining, with a faint greyish dust. Antennae extending to the mouth-border, 

 with the second joint and the rather broad third joint broadly reddish on the interior 

 side, the last only on the basal half ; arista not very long, miscroscopically pubescent ; 

 palpi and proboscis black. Thorax and scutellum very glistening bluish ; chaeto- 

 taxy as in the preceding species, scutellum with 2-3 bristly hairs. Squamulae and 

 halteres as in the preceding. Abdomen very shining, but less bluish than the back of 

 mesonotum ; ovipositor about 1 mm. long. Legs black, the tarsi with the two basal 

 joints and part of the third joint pale yellowish. Wings as in the preceding species, 

 but proportionally broader, they are quite crystalline, even at fore border ; veins 

 very pale yellowish.
