REPORT OF THE STATE ENTOMOLOGIST IQI7 II9 
abels and one, though belonging to another group, was labeled in 
iddition Cecidomyia pellex. The general appearance of 
hese insects is so similar that they were doubtless considered as 
elonging to one species and were presumably reared from the 
‘amiliar gall on ash, generally ascribed to Cecidomyia pellex, 
Gall. The gall from which this insect was reared, if our associa- 
jon be correct, is a large, tumid, green, reddish or brownish midrib 
swelling ranging in length from 5 to 15 cm. The larger galls contain 
tom 30 to even so or more larvae which are found irregularly scat- 
ered along the length of the deep fold evidently caused by their 
uctivities. 
Male. Length 1.25 mm. Antennae one-half longer than the 
Jody, thickly haired, light brown; 14 segments, the fifth with stems 
sne and one-half and three times their diameters, respectively; 
erminal segment, basal enlargement subglobose, the basal portion 
of the stem with a length over twice its 
diameter, the distal enlargement much 
produced, fusiform. Palpi; the first 
segment short, stout, expanded distally, 
the second stout, subquadrate, with a 
length about twice its diameter, the third 
one-fourth longer, more slender than the 
second, the fourth more than twice the 
length of the third, more slender. Meso- 
notum dark brown, the submedian lines 
thickly haired. Scutellum pale yellow- 
ish brown, postscutellum a little darker. 
Abdomen dark brown, rather thickly 
haired. Wings hyaline, costa pale straw; 
halteres pale yellowish. Legs a vari- 
able yellowish brown, the femora dis- Fig. 39 Contarinia 
tally and the tarsal segments somewhat canadensis, fifth anten- 
darker: claws long, slender, strongly nal segment of male (en- 
curved, the pulvilli a little longer than _larged, original) 
the claws. Genitalia; dorsal plate short, 
stout, deeply and triangularly incised, the lobes broadly rounded. 
Female. Length3mm. Antennae extending to the third abdominal 
segment, sparsely haired, light brown; 14 segments, the fifth witha 
stem about one-fifth the length of the subcylindric basal enlargement, 
which latter has a length about twice its diameter; terminal seg- 
ment reduced, the enlargement with a length about twice its diameter, 
apically a short, stout appendage. Palpi; the first segment short, 
stout, slightly expanded at the distal fourth, the second stout, 
rectangular, with a length about twice its diameter, the third a little 
longer, more slender, the fourth one-half longer and more slender 
than the third. Color, wing and leg characters about as in the oppo- 
site sex. Ovipositor about as long as the abdomen, the terminal 
lobes indistinct. Type Cecid. 1027.
