158 THE ENTOMOLOGIST. 



ably longer and narrower than the second posterior cell, its base nearer 

 the base of the wing than that of the second posterior cell, its stem 

 about half the length of the cell ; stem of the second posterior cell not 

 as long as the cell ; posterior cross-vein nearly twice its own length 

 distant from the mid ; sixth vein curved almost at right angles at the 

 apex. The male genitalia have rather a narrow basal lobe, with a long 

 curved lateral process composed of several narrow laminae, and nearer 

 the clasper another process, shorter, and composed of finer parts ; the 

 clasper terminates in a small jointed process. Length, 3-5 to 4 mm. 



Habitat. Bihe, Angola, Portuguese West Africa (Dr. Creighton 

 Wellman). 



Observations. — The four females sent by Dr. Creighton Well- 

 man all show the marked seventh scaled vein, but the males do 

 not. There is variation in size, showing, as usual, that exact 

 measurements of Culicids are of no diagnostic value. This 

 species might easily be mistaken at first for Culex fatigans, 

 Wied., and, on more careful examination, to be near C. creticus, 

 Theob., owing to the white scaled line on the femora and tibiae ; 

 but a microscopic, or even a careful hand-lens, examination will 

 at once reveal the seventh scaled vein. 



The original type is in the British Museum, and all the 

 specimens redescribed here. There were three males sent with 

 the females. 



Further notes on this genus will shortly be issued in the 

 ' Archiv der Parasitologic ' on important material collected and 

 described by M. Veutillon. 



A LIST OF THE " MACRO-LEPIDOPTERA '' OF 

 LANCASTER AND DISTRICT. 



By C. H. Forsythe. 



(Continued from p. 135.) 



Triphana ianthina. — Generally distributed throughout the district ; 

 comes to sugared ragwort flowers in July and August. 



T. interjecta. — Uncommon. I have only taken examples near 

 Heysham, Hest Bank, and in the County Asylum grounds in July. 



T. comes (orboiia). — Comes freely to sugar in July and August, and 

 is generally distributed. This species is very variable. 



T. pronnba. — Abundant at sugar in July and August everywhere. 

 This is another very variable species in colour — from silver-grey to 

 black-brown 



Aviphipyra tragopqgonis. — Fairly common everywhere at sugar in 

 August. 



Mania maura. — Comes to sugar in Aqueduct Wood and other 

 localities on the banks of the Lune at the end of July. I have also 

 taken specimens in the County Asylum grounds.
