A NEW CULICID FROM SENEGAL AND NOTES ON 
THE SPECIES OF MOSQUITOES, ETC. 
By F. V. THEOBALD, M.A. 
Amongst a large collection of mosquitoes and other biting-mouthed diptera collected and bred by 
Drs. Dutton and Todd during their recent expedition to Senegal, is a large series of a new Culicid, 
resembling in habits the Deiuoce/ites cancer, Theobald, of the West Indies. It comes very near my genera 
Stegomyia* and Macleaya,\ but cannot be placed in either. Without an examination of the scale structure, 
one would certainly place it in Cu/ex, but hasty microscopic examination shows it to come much nearer 
the two first-named genera. I propose for it the generic name Catageiomyia, (/caraye/o?, subterranean, 
and /mvla, a fly). 
Gknus Catageiomyia. Nov. gen. 
Head covered with rather irregular loosely-applied flat scales, a few narrow-curved ones on the 
nape in the 9 > spreading rather further on to the occiput in the $ , also with numerous narrow, upright, 
forked scales. Palpi short in the 9 > composed of three segments, the last one as long as the two basal 
ones ; in the $ the palpi are long, but not nearly as long as the proboscis, the two apical joints short, the 
apical one slightly shorter than the penultimate, the apex of the antepenultimate slightly expanded, dense 
hairs on each side of the penultimate and on one side of the apex of the antepenultimate ; apex bristly. 
Thorax with narrow-curved scales on the mesonotum ; small flat ones on the mid lobe of the scutellum ; 
narrow-curved ones on the lateral lobes. 
This genus thus differs from Stcgomyia in (i) having narrow-curved scales on the back of the head, 
(2) narrow-curved scales on the lateral lobes of the scutellum ; and from Macleaya in (1) having the flat 
cephalic scales more loosely applied, (2) in having the $ palpi much shorter than the proboscis. 
In general appearance it resembles a Cu/ex of the fatigans group, but the scale structure, palpi, 
etc., are quite distinct. 
Catageiomyia senegalensis. N. sp. 
Thorax rich, deep brown, with small scattered golden scales, paler before the scutellum ; 
numerous long dark bristles posteriori)'. Abdomen black, with basal white bands, which spread out 
laterally ; venter, with broad basal white bands ; head ornamented, with grey and black ; proboscis deep 
brown, unbanded ; legs deep brown, unbanded, except the hind tibiae, which have an apical white band ; 
venter of femora, white. Wings with brown-scaled veins. Male palpi shorter than proboscis. 
9 . Head clothed with loosely applied flat scales all over, a few narrow curved ones behind, and 
narrow upright brown forked ones scattered about ; the flat scales are in black and white areas, and the 
narrow curved ones are pale grey ; there are dark brown bristles projecting in front ; eyes purple when 
dead ; palpi, brown, three-jointed, the last joint as long as the two basal ones ; antennae, brown ; basal 
joint pale testaceous, with grey sheen, and a few small dark scales internally ; clypeus and proboscis, deep 
brown.
