A CONE-LIKE CECIDOMYIID GALL ON BIGELQVIA. EY C. H. TYLER TOWNSEND, LAS CKUCES, N. MEX. A cone-like cecidomyiid gall was
found on BigeZoaiu gr~veotem, near
Gat10 Spring, N, M,, June 21, 1892.
They were also found west of Apache
Spring and the Rio Apache, June 22.
One of the latter, opcned on that datc,
revealed three small larvae which were
apparehtly cecidomyiidan, Both the
above localities are in western Socosro
County, New Mexico. This cecido-
myiid may be lcnown as Cecidomyia
JigeZovi~e-sfit-ohiLoides.
Gail.-Length, 8 to 10 mm. ; width 3 to
6 tnm. Rather elongate, s~~bcylindrical in general form, but little narrower on iipical than on basal portion. Borne on sidc of
twig, to which it is attached by a short and narrow stem. Rather compact, formed
of many narrpwed overlnpping stip~iles,
but thew are apparently united and grown together, forming a compact body, only
the terminal elongate portions of the ouher stipules free and showing as curled tips on the outside of the gall. The stipules arranged like the cone of a pfne tree, all extending nearly upward but slightly out- ward from the central longitudinal cell. Ot~tside of gall covered with a thin white woolly pubescence, the gall greenish beneath thi~, ~ n d the rather long narrow more or less curled free terminal ends of stipules protruding through the woolliness, and
growing more numerous toward tip of gall. The central cell is from 4 to 5 mm. long, I mm. wide, quite cylindrical, its walls a little hardened in texture. It doe8 not
extend to bme of gall.
Described from three galls ; one alco-
ho1ic and two dried specimens.
Abo~~t
the middle of At~gt~st, 1892, the pill
box containing the two dried galls
was opened and found to contain a
metallic dark green niicrol~yn~enop-
teson with fit1 nvipo~itor as long as it$ body. It is n minute spccies. Upon
opening one of the dried galls, scveral
very minute transformed hyinenopter-
om parasites were found in the terminal
portion of the cell, and a well-formed
cecidomyiid pupa with vcry long leg
sheaths fo~~nd in the basal portion.
As severd larvae appear to inhabit the
singlc cell in each gdl, the minute
parasites probably clcveloped~ in the
other ceciclomyiid larvae leaving one
unto~~ched to isansforn~. The tninute
parasites were without ovipositor and
are doubtIeas n~ales of the above men-
tioned species. The uther dried gall,
which was the smallest one, cont&ied
the skin of a ceciclo~nyiid ppa and
transformed female of the above inicso-
hymenopteson. This lqwenopterous
parasite has been determined by Ms.
WI~. H. Ashcad as Tovym~s sp.
It is a little over I mn. in le~gth
{P), with nearly clear wings. Ovi-
positor a little over I mm,
