This insect was described some months since, but by some error the 

 MS. was not published as I expected, so I now use it as a conclusion 

 to " Mosquito Notes, No. 5." 



Ludlowia tnifiima, n. sp. — Head light brown, covered with flat light 

 yellow or yellowish-white scales, two brown bristles projecting forward 

 between the eyes, a few brown fork scales in the nape ; antennae brown, 

 verticels and pubescence brown, and normal; basal joint testaceous, with 

 a few short brown hairs ; second and third joints have a few flat brown 

 scales ; palpi brown, apical joints missing, those remaining heavily brown- 

 scaled ; proboscis brown, tip light ; eyes brown ; clypeus brown, with 

 " frosty " tomentum. 



Thorax : prothoracic lobes testaceous, with a few brown bristles ; 

 mesonotum dark brown, partly denuded, but the remaining scales on each 

 insect are dark brown slender (*urved scales (not hairs) and a few dark 

 brown bristles over the scutellum and wing joint ; scutellum with dark, 

 brown slender curved scales and brown bristles ; pleura light, with a 

 couple of brown spots and a few white scales ; metanotum dark brown. 



Abdomen light, with dark brown scales and narrow ochraceous basal 

 bands extending laterally as small basal light spots ; venter mostly light- 

 scaled. 



Legs as a whole brown, but the colour changing with the direction of 

 the light to a light brownish gray ; coxge and trochanters light; femora 

 dark dorsally, ventrally almost white, tiny apical light spots on femora 

 and tibiae, distally dark, the rest of the joints missing except on hind legs, 

 where the ungues are simple and equal. 



Wings clear, densely covered with brown scales, lateral scales broadly 

 lanceolate, median broadly truncate, showing very little if any symmetry ; 

 spine-like scales on the costa. Cells not so markedly short as in 

 Chamberlainii. First submarginal about 1/7 long, and nearly the same 

 width as second posterior, both very narrow; stem of former not half as 

 long as cell, and about a fourth shorter than that of second posterior ; 

 mid-cross-vein meets supernumerary, and is slightly longer; posterior 

 cross-vein slightly shorter than mid, and about twice its own length distant. 

 Length, 2.5 mm.
