EIGHT NEW MOSQUITOS IX THE BRITISH MUSEUM COLLECTION. 363 



It is interesting to note that Mr. Bacot found a definite fauna in the leaf-axils ; 

 larvae of Stegomyia simpsoni, Theo., and Uranotaenia ornata, Theo., were nearly 

 always present with Eretmopodites dracaenae, and often also a species of Ceratopogon 

 and a small Psychodid (? Pericoma sp.). With the exception of Stegomyia simpsoni 

 these larvae were found nowhere else. 



Wyeomyia grenadensis, sp. n. 



$. Closely related to W. clasoleuca, D. and K., from which it differs as follows : — 

 Scales on prothoracic lobes blue or violet below, coppery above ; those on the scutum 

 (mesonotum) black, with scarcely any metallic lustre ; those on the area behind and 

 above the prothoracic lobes almost white. Tibiae, front tarsi, and first three joints 

 of the hind tarsi black-scaled below as well as above ; middle tarsi pale-scaled below, 

 becoming paler apically, scales on the apical joints whitish yellow ; fourth hind tarsal 

 joint with white scales below on the basal four-fifths ; fifth hind tarsal entirely white- 

 scaled below. Terminal abdominal setae dark. 



Grenada (A. Macdonald). 



Six females received by the Wellcome Bureau of Scientific Research ; type and 

 two other specimens presented to the British Museum. 



The slight colour differences between this and W. clasoleuca would seem to indicate 

 that the two are only geographical species, but as the males of both are unknown the 

 point must remain undecided at present. 



Anopheles domicolus, sp. n. 



9. Head with the usual white and black upright forked scales, the former 

 constituting a moderately large patch on the vertex ; very long sinuous white scales 

 projecting forwards from the front. Proboscis black- scaled. Palpi black-scaled, 

 with a narrow white ring embracing the articulation of the first and second joints, 

 and two much broader white rings, one covering the tip of the second joint and the 

 basal third of the third joint, the other covering the apex of the third joint and the 

 whole of the fourth ; these two outer white rings are equal in breadth and distinctly 

 broader than the black ring which separates them ; the terminal palpal joint is barely 

 one-third as long as the penultimate. Antennae with the basal joint yellowish ; 

 second joint with some small white scales ; second and following joints (except the 

 last two) with whitish hairs. Thorax : prothoracic lobes with a number of black 

 bristles, prosternum with a single bristle ; scutum with black bristles and very narrow, 

 slightly curved white scales, the latter more dense towards the front margin ; sides 

 of scutum rather broadly dark brown, the median area light grey, without distinct 

 markings. Abdomen blackish, the hairs yellowish ; no scales. Legs black, the tips 

 of the tibiae and of the first two tarsal joints on all the legs white ; on the hind legs 

 the tips of the third and fourth and the bases of the second, third, fourth and fifth 

 tarsal joints are also white. Wings with the scales of the lateral series linear-lanceolate ; 

 markings as follows : — costa with five black spots, the first basal and about as long 

 as the third, second and fourth a little shorter, fifth less than half as long as the 

 fourth ; first three separated by very narrow white spots, the white between the 

 third, fourth and fifth broader. A small black spot in the wing fringe at the tip.
