*272 GNATS OR MOSQUITOES — CHAPTER XI 



with apical, lateral j^olden spots, and golden venter. Legs dark, with 

 some deep purple retlcctions, no white on fore legs, the mid feet have 

 the second and third tarsi white beneath (hind tarsi missing). Wings 

 with " 2," only a short way in advance of the " 3," and " 4," joining the 

 latter. Lenfjth. — 8 to 8*5 mm. 



Habitat. — Amazon (Bates), 1861. 



Observations. — " Described from two ? 's in the Hope Collection at 

 Oxford University. It resembles M.fcrox, but can at once be told by the 

 abdomen being brilliant purple instead of steel-blue, with apical yellow 

 bands, and by the four, not five, jointed palpi. The venation also differs 

 in regard to the position of the cross- veins." 



6. MEGARHINA LUTESCENS, Thoob. (Monog., I, p. 233). 



Caudal adornment yellow and black. Third hind tarsal joints 

 white, except at very apex. Thorax dull bronze, shading to 

 mauve and green laterally, with azure patches over the roots 

 of the wings. 



Thorax brown, with small dull bronzy scales above and broader 

 mauve and green ones at the sides, and an azure patch over the roots of 

 the wings ; pleurae yellowish, darker in tlie middle, with a line of silvery 

 scales. Abdomen covered with golden-green scales, and with golden 

 caudal tufts on the sixth and seventh segments. Legs black, with 

 coppery-green and purple metallic reflection, and golden-yellow bases 

 to femora ; second tarsal joint of hind legs white. Length. — 7*5 mm. 



Habitat. — Salisbury, Mashonaland (G. A. K. Marshall, 1879). June. 



Observations. — " Described from single <? only, in nearly perfect con- 

 dition. This is a vei'y beautiful species, with a great play of colours, 

 the golden abdominal scales appearing like burnished brass in some 

 lights ; the yellow caudal tuft should separate it at once from other 

 species."

 nape partly gi'een ; scutellum and first two abdominal segments gi*een, 

 but tlie remaining segments blue. Wings rather shorter than abdomen, 

 their costa partly green-scaled. LcufjtJi. — 2^ Dutch lines.
