axillary lobe very slightly developed ; they are somewhat blackish tinged. 

 Veins black; the discal cell very long and narrow, and hence the veins 

 issuing from it short; the anal vein weak and not reaching the mar- 

 gin. No stigma. Balteres white. 



Female. Quite similar to the male, also in the structure of the 

 head. The eighth abdominal segment forms a short, conical ovipositor, 

 terminating with tvvo somewhat long, thin styles. 



Length 2,8 — 3,4 mm. 



This species is very interesting with regard to the structure of 

 the head and the wings, and it might perhaps, as already suggested 

 by Loew, serve as type for a separate genus. 



L. sphenoptera is very rare in Denmark, and it was for the first 

 time taken in 1909; Ordrup Krat and Ermelund (the author); my dates 

 are Vs — ''/o, so that it is evidently a late occurring species. It occurs 

 on humid, somewhat open piaces in woods and thickets in the low 

 herbage; it was seen hovering slowly over the piants and was taken 

 sitting on Urtica and Impatiens. 



Geographical distribution: — Europe down into Italy, and further 

 into North Africa; its northern limit lies in Denmark, and it occurs 

 also in England (according to specimens sent to me from Mr. Verrall). 



12. Euthyneura Macq. 



{Anthalia Zett.) 



Small species, of black, rarely yellow colour {pallida Zett.). The 

 head globular, slightly narrower than thorax, arched behind and here 

 with some hairs. Eyes large, in the male either touching or very 

 narrowly separated, in the female well separated; the incision in the 

 inner eye-margin present. Vertex with three ocelli and a pair of 

 small bristles. Antennæ inserted near to each other, in the middle; 

 they are short, consisting of five joints; the two 

 basal joints are short, the third a little elongated, ^;^§^"' 

 compressed and somewhat ovate, but pointed at 



the apex; the two last loints form a very short ^. „^ . ^

 developed. The proboscis is shorter or longer, 

 from somewhat shorter than the head to about twice as long; it is 

 stretched horizontally forwards or obliquely downwards; the maxil- 

 lary palpi are one-jointed, somewhat long and a httle compressed; 

 they rest on the proboscis. The mouth parts I have otherwise not 

 been able to examine. Thorax is rectangular, high, and arched 

 above; pro- and metathorax very small. The thoracic disc has
