Genus Theobaldia. 275 



lens, there are two median parallel dark bare lines ; scutellum 

 brown, with broader, more spindle-shaped and more appressed 

 creamy scales ; posterior border-bristles dark brown ; metanotum 

 deep brown ; pleurae brown, with flat creamy white scales. 



Abdomen deep blackish-brown, the segments with apical 

 creamy white bands ; in the second segment the white band 

 sends a median triangular process towards the base ; first 

 segment with median flat white scales only ; posterior border- 

 bristles pale, short in the middle of the segments, longer at the 

 sides ; venter pale scaled in the middle. 



Legs deep brown, unbanded ; femora pale at the base and 

 ventrally. 



Wings with the first sub-marginal cell longer and narrower 

 than the second posterior cell, its base a little nearer the base 

 of the wing, its stem about half the length of the cell ; stem of 

 the second posterior cell about two-thirds the length of the cell ; 

 posterior cross-vein rather more than its own length distant 

 from the mid ; hal teres ochraceous. 



Length. — 3 ' 5 mm. 



Habitat. — Algeria (Dr. Edmond Sergent). 



Observations. — A very marked species, easily told by the very 

 prominent Y-shaped pale mark on the second abdominal segment 

 arising from the apical pale border and by the broad curved 

 scales on the head and thorax. It has to be placed in a new 

 genus, as no Culicid I have seen comes near it in scale structure. 

 The new generic position was noticed by Dr. Edmond Sergent, 

 who sent me the specimen, and the name of genus and species 

 proposed by liim is that under which it is described.

* 



Blanchard renamed this genus Theobaldinella because the 

 name Theobaldms had been previously used by Neville, Theobakh'a 

 had not, so that Neveu-Lemaire's name is retained.
