Probably common. Eochford, Essex; Patching and Ang- 

 mering, Sussex ; Woking, Surrey ; Brockenhurst, Hants ; Long- 

 ner Hall, Shrewsbury. 



3. T. theohaldi, Meij. — The adults are difficult to separate 

 from those of T. morsitans, though the larvae are very distinct. 

 In the male of T. theohaldi the front metatarsus is scarcely at all 

 longer than the remaining four joints together. In the female 

 the proboscis has numerous pale scales, especially in the middle 

 at the sides. Eight or nine teeth in the pecten of the larval 

 air-tube, placed more transversely than in T. morsitans ; five or 

 six spines beyond the pecten. Meijere states that the larva is 

 yellowish or greenish white, while that of T. morsitans is blackish 

 grey. He also says that the air-tube of the larva of this species 

 is relatively shorter and broader, but I do not find this to be the 

 case. Figures 3 and 4 represent the larval air-tubes of 2\ morsi-

tans and T. theohaldi respectively ; they were drawn by my wife 

 from specimens taken in the New Forest by Mr. C. 0. Water- 

 house, and mounted in balsam. 



Quite as common as T. morsitans. Has been taken in Scot- 

 land at Dingwall, Cromarty {Lt.-Col. Yerhunj). 



The specimens described by Theobald (Men. Cul. i. p. 335) as 

 Culcx ficalhii (so named by Prof. Grassi) are T. theohaldi, and were 

 certainly, I think, wrongly named, as G. ficalhii was originally de- 

 scribed as having spotted wings. Specimens answering Noe's descrip- 

 tion have been received at the British Museum from the Punjab ; one 

 of these was recorded by Theobald as C. annulatus. It is improbable 

 that the true Th. annnlata occurs in India.
