NOTES ON SOME TBANSVAAL MOSQUITOES. 107 



after examining the numerous specimens, the smallest and the 

 narrow pale-banded proboscis forms are my C. dissimilis ; the 

 large, broad, pale-banded proboscis forms are my C. hirsutipalpis. 

 I cannot detect any differences except in size and general appear- 

 ance, but in the large Transvaal series every gradation from one 

 to the other could be found. I therefore propose to sink C. hir- 

 sutipalpis as a large variety of C. dissimilis. The same is seen in 

 the Pyretopliorus costalis ; some specimens measure 5 mm., one 

 only 3*4 mm., and in the smaller forms the leg markings are 

 less conspicuous. 



This collection of some hundreds of specimens is poor in 

 Anophelines, which seem to be only abundant in certain areas of 

 the Transvaal and not uniformly spread over it as in some warm 

 countries. 



Besides P. costalis the following also occur : — CclUa squamosa, 

 Theob., Pyretopliorus cinereus, Theob., Myzorhynchusmauritianus, 

 Grandpr6, and Myzomyia fmiesta, Giles. 



The large Theobaldia spathipalpis of Eondani also occurs in 

 the collection, so we now have it known in Africa at the Cape, 

 Transvaal, Sudan, Egypt, and Algeria, as well as in Southern 

 Europe, the Mediterranean Islands, Canaries, and the Azores. 



Banksiella luteolateralis, Theobald, var. circumluteola, nov. var. 



Head like the type, also proboscis and antennae ; palpi of female 

 all black. Thorax with creamy lateral areas, which unite in front, 

 forming a continuous mass behind the head, the dark median area 

 having only bronzy-brown scales, and being narrowed in front. 



The wings have more brown-scaled areas than the type, the only 

 creamy-scaled veins being the basal half of the first long vein and 

 the fifth, except its upper branch ; there are also pale lateral scales 

 on the apical half of the subcostal, and a few indistinct ones on the 

 basal part of the second and fourth veins. The stem of the first 

 fork-cell is half the length of the cell, and that of the second about 

 two-thirds the length of the cell. Abdomen as in type, also legs. 

 Length 5 mm. 



Habitat. Transvaal (Mr. Simpson). 



Observations. — Differs from the type and other varieties in 

 the pale lateral thoracic area extending around the front of the 

 thorax, and by the less pale scaled areas on the wings. 



Etiorleptiomyia mediolineata, Theob. 

 (1st Eept. Wellcome Res. Labs. p. 71) (1904). 

 The single specimen (a female) in the collection shows some 

 slight variations from the type. 



The palpi are white-tipped instead of being all black. The 

 thorax is more ornate, having an area of bronzy scales on each side 

 in front and behind, and a small area on each side between them, 

 these areas separated by the golden scales. The scutellum has some
