sexnilis, being, however, distinct owing to the basal iufuscatiou of the 

 wind's, the red upper side of the proboscis, and from the first by the 

 much broader frons of the female. 



Type $ and another specimen of the same sex from Bushmanland, 

 Jackal's Water (Cape), October, 1911 (K. M. Lightfoot). 



Length of the body 7-7'5 mm. ; of the proboscis 3 mm. 



Head as in the preceding ; third antennal joint black, and distinctly 

 shorter ; proboscis strong, red above, but black at end and below, the 

 base exoepted, which is dark red ; the proboscis is besides much 

 shorter, being hardly longer than the thorax. Thorax and scutellum 

 as in the preceding. Abdomen black, narrowly red on the sides and 

 with the venter altogether red ; towards the end there are very long 

 and white bristly hairs, which are entirely wanting in eurldnatus. 

 Legs as in the preceding. Wings with the basal infuscation more 

 blackish than reddish and limited to the second basal cell ; first pos- 

 terior cell very narrow, long and acute, but less than in miuidus ; 

 disroidal cell very small, as long as the second posterior cell. 



BOMBTLIUS GLOBULUS, Sp. UOV., $ . 



A verv small species of globular shape, distinct by the long hairs of 

 body, by the red antennae, proboscis and legs, by the black scutellum 

 (an aberrant character in the present group), by the very narrow frons 

 of the female and by the entirely hyaline wings. 



Tvpe 9 , and another specimen of the same sex from Namaqualand, 

 O'Okiep (Cape), September, 1890 (E. M. Lightfoot). 



Length of the body 5 mm.; of the proboscis T5-2 mm. Body 

 entirely black, and entirely clothed with long yellowish hairs, without 

 any black hair. Frons very narrow, about half as broad as in the two 

 preceding species ; antennae entirely pale yellow, provided at base with 

 long hairs, with the third joint rather thick and pointed, ending with 

 a style longer than that of the two preceding species ; proboscis short 

 and strong, red, with a black tip. Thorax clothed with long, pale 

 yellowish and shiny sericeous hairs, which are almost whitish on the 

 lower part of the pleurae ; there are no distinct bristles. Scutellum 

 entirely black, haired like the thorax. Abdomen entirely black, but 

 red on the venter ; it is hairy like the thorax ; the bristles at the hind 

 border of the segments are thin and hardly distinguishable between 

 the hairs. Legs entirely yellowish, and with yellowish bristles, those 

 on the femora Avell developed. Wings quite hyaline, with yellow veins 

 which are darkened at end ; basal comb very small ; marginal cell also 

 very broad, the upper branch of the cubital fork being very strongly
