Length, 2-3 mm. Head transverse, narrower than thorax; vertex 
entirely and temples above granularly sculptured and pilose ; frons smooth 
and glabrous puce with a narrow orbital line faintly granular) with 
a very small but distinct median tubercule in front of median ocellus ; 
face, cheeks, and temples below smooth and sparsely hairy ; occiput 
distinctly margined ; viewed from front the head is subtriangular and 
broader than high ; antennae weji weakly clavate ; scape moderately 
long and somewhat curved ; pedicel fully twice as long as thick; third 
joint as long and about as thick as pedicel; fourth approximately two- 
thirds as long as third and about as thick ; fifth not quite as long as fourth 
and slightly thicker, about as broad as long ; ; sixth to ninth subequal and 
subquadrate or very slightly longer than thick; tenth conical and very 
slightly longer than preceding joint. Thorax ovoid, broadest before tegulae ; 
pronotüm rounded in front and deeply and broadly emarginate behind ; 
parapsidal grooves воша and sharply impressed ; scutellum slightly 
convex and about twice as broad as long; axillae transverse, deeply 
nd scutellum finely granular and closely pilose ; propodeum with a shallow 
median channel bounded on each side by prominent carina, transversely 
rugose between сагіпае and very faintly granular and pilose laterally ; 
mesopleura glabrous and polished with three of four distinct longitudinal 
striae near dorsal margin; metapleura pilose but practically smooth ; legs 
moderately long and slender, posterior tibiae with two unequal spurs ; 
veins distinct though more or less vestigial, the submarginal faintly 
traceable for nearly half length of wing and terminating in a nearly 
obsolete knob; whole surface of wing ciliated, basal portion a little more 
sparsely so than remainder; hindwing with a non-ciliated area extending 
obliquely basad from. hooklets to posterior margin. Abdomen as long as 
head and thorax or a little longer, as broad as thorax, broadest at apex of 
second tergite, and Ginny margined laterally ; first tergite broader at 
apex than long down middle and strongly longitudinally striated ; second 
tergite a little more than twice as long as first, much broader at apex than 
at base, with a large ovate and well-defined depressed area on each side of 
middle at base, surface of tergite mostly smooth and glabrous but with several 
elongate punctures or short striations at basal middle, the depressed areas 
very finely punctured and pilose within, and lateral margins of tergite 
sparsely hairy ; tergites beyond second, short, weakly punctate, and hairy ; 
ovipositor concealed. 
Black ; antennae black; coxae reis with thorax; legs, except 
coxae, reddish- testaceous ; marginal carina of abdomen reddish beneath ; 
"tiros faintly fuscous, the аванса, not uniform but more intense 
median portion of wing; hindwing also faintly ete with hyaline 
ind behind hooklets. 
Similar in every way to female except in antennae. These are not 
at all clavate, third and fourth joints are subequal and each a little longer 
than pedicel, fifth a little longer than thick, sixth to ninth subequal and 
distinctly longer than thick, tenth ovate and about one and a half times as 
long as ninth ; all flagellar diet cylindrical and very shortly petiolate but 
not serrate. 
— from fifteen specimens received, as already stated, from 
E. S. Gourlay. The species is without much doubt parasitic upon à 
Ойлана, possibly Cecidomyia oleariae Maskell. It seems highly pro obable 
that more than one species of Cecidomyidae has been confused under this 
name by Maskell.
