190 NEMATUS LEUCOSTIGMA. 



small tubercles, each ending in a short hair ; at the 

 sides the segments project in ridges ; over the anal seg- 

 ment are two often only one broad black bands of 

 a variable size (generally each band is contracted in 

 the middle) ; the cerci are black. Previous to spinning 

 the head is, as a rule, of a lighter colour, and often 

 there is a distinct black splash on the face ; the anal 

 markings are very faint, and the body yellowish- white. 

 The length is from 5 7 lines. 



Leucostictus is a tolerably common insect. It is 

 found everywhere in Scotland. I have seen English 

 examples from Manchester, Glanville's Wootton, Glou- 

 cester, and the London district. 



Continental distribution : Scandinavia, Holland, 

 Germany.

Black, the orbits (especially behind) brownish, clypeus, labrum, 

 and a wedge-shaped mark between and below the antennas, yellowish- 

 white ; the tegulae, the pronotum at the base, and legs, clear white, 

 inclining to yellow, especially on the legs; the coxae (except at the 

 extreme base) and the greater part of the femora black, the base 

 and apex of femora inclining to fulvous at the junction with the black ; 

 the apex of hind tibiae and tarsi blackish. Wings clear hyaline ; costa 

 and stigma white, the latter darker at the apex. In the hind wings the 

 upper middle cellule is shorter than the lower, through the recurrent 

 nervure being received beyond the transverse cubital instead of before 

 it as in N. leucostictus. Antennae black, brownish beneath. Vertex finely 

 punctured. ? . 

 Length 2 lines. 



A species very closely allied to JV". leucostictus. The 

 white on the pronotum is much less extended, being 

 confined to the base close to the tegulge ; the third 

 cubital cellule is smaller, not being much broader than 

 long, the costa is of a clearer white, the femora are
