many black seta?. Mesonotum black, covered with golden yellowish or bright red- 

 dish brown scales and with creamy ones at the sides; over the roots of the wings 

 tufts of golden brown bristles; scutellum deep brown, almost black, trilobate, clothed 

 with pale scales and each lobe with a tuft of golden-brown bristles. [Postnotum 

 black, pleura! dark brown with patches of pale scales. 



Abdomen densely black scaled with clear white basal bands, not or only little 

 contracted in the middle line not forming distinct broad lateral patches; posterior 

 borders with clear pale golden bristles; venter white and black scaled. 



Wings with brown, almost black scaled veins; first sub-marginal cell consider- 

 ably narrower and longer than second posterior cell; petiole of first submarginal 

 cell as long as the cell, that of second posterior cell a little longer; basal cross-vein 

 very close to the anterior cross-vein. Halteres with ochraceous stem; knob fuscous 

 with grey scales. Legs unhanded; coxae brown with white scales; femora and tibia' 

 densely covered above with greyish white scales; knee spots white, apices of femora 

 before the spots deep black; hind tibia with a very characteristic white stripe on 

 the outer side. Claw formula 1.1 — 1.1 — 1.1. Length of body about four mm. 



I have never seen either male or larva; the last-named is unknown. 



The species was brought me by Mr. Kryger who caught it in the western 

 part of Jutland at Linding near Varde. He has only caught three specimens, which 

 I determined as Ochlerotatus nigrina (Eckstein). Mr. Edwakds has been kind enough 

 to verify the determination. He refers it to 0. sticticus Mg. var. concinnus Steph. and 

 gives the following synonymy. 0. sticticus = sylvce Theobald = dorsovittatus Ville- 

 neuve = ? nigrinus Eckstein. — The best distinguishing feature is the white stripe 

 on the outer side of hind tibia?. See further p. 96. 



Geographical distribution: 0. sticticus Meigen var. concinnus Steph. seems 

 to be rare everywhere; Mr. Edwards states that it has hitherto been found in 

 England, Scotland, France, Germany and Siberia.
