where they are sometimes, but not always, 
prolonged backwards at the sides. Sternites 
with dark apical bands which tend to be pro- 
longed forwards in the midline. These for- 
ward prolongations in some cases very broad 
and conspicuous, in others narrow and incon- 
spicuous or absent. 
Terminalia (Figs, la, 2a) with style broad, 
well formed but with a few oblique wrinkles 
about the middle, with small terminal ap- 
pendage and two subapical setulae. Subapical 
lobe of coxite with narrow leaflet accom- 
panied by a markedly flattened seta. Two sets 
of modified setae, as figured. Coxite not ab- 
normally broad and with no more than the 
usual complement of long setae on the inner 
face. Phallosome with tip of inner division of 
dorsal arm modified as shown (Fig. la), outer 
division ("basal arm”) strongly developed, 
scooplike. Ventral arm much as in C. pipiens . 
Paraprocts with well- developed crown and 
basal arm. Xth tergites rather strongly sclero- 
tized, each with 4 small setulae in the usual 
position. IXth tergite with setigerous lobes 
very broad and flat, each with about 10 setae. 
adult female: Much as male but with 
palps only a little more than one-fifth the 
length of the proboscis. Pharynx and termi- 
nalia as figured (Fig. 4). 
pupa: Not seen. 
larva: (Fig. 5). Head broader than long in 
about the proportion of four to three, in most 
cases darker than the remainder. Antenna 
about five-eighths the length of the head, more 
or less unicolorous except at extreme base, 
moderately strongly spiculate basad of the 
insertion of the antennal tuft but with only a 
few spicules distad of this point. Antennal
