whiclt increase in U'natli and str('n<rth to just before' the pn'ajeical bristle, 
wliero tlio last one is almost bristle' like; peeste'ree-ve'iitral snrlae'e baree 
except at basev, binel tibia as in aellcaiida. 
The tbeeracic chaetotaxy is as in seticaada. d'be cheek is elistinctly 
higher than in the pre'ceding species, being almost half as high as the ('ye'; 
the bristling of freens is the same in be)tb speciess, bnt rather stre)ng('r 
in binpina. The female of this species may be separateul from that eef 
sedcaiida by the higher cheek, (vbich in the latter is barely eene-tbirel the' 
eye^ height; its me)re eebsenre brenvnisb yellow ce)lor; the longer sixth 
ahelomieial segment, which is about as long as the filth, anel its rather 
larger size. Length, 75-4.0 mm. 
In the lllineds State Laboratory of Natui'al History there are s))ecimens 
from the following Illinois localiti(^s: White Heath; St. Joseph; Algon- 
(piin ; Champaign; (Jnincy ; and Urhana. 
.'Melander in his recent synopsis of this family suggests the probability 
of connexa Say, being the female of this species, bnt the acceptaiu^e ol 
this synonymy is not desirable, because of the number ol sj)ecies to which 
Say’s des('ri|)tion would apply more or less fittingly, unless one is par¬ 
ticularly anxious to preserve Say’s name. There is a female in the mate¬ 
rial here naim'd by Cocpnllett as connexa Say which is nndonhtedly 
hi spina Loew.

Mate. — Reddish yellow, slightly shining, head parts opacpie. Arista 
brown, yellow at ha.se. Wings clear, veins yellow, th(' cross vein being 
slightly more distinct than the other veins. All bristles black. 
Profile of head as shown in Fig. Hi; arista very short haired ; hairs on 
occiput and clu'eks more distinct than usual. Arista ])uhescent. IMeso- 
notum with 4 pairs of dorso-central l)ristles, the trout pair strong; acro- 
stichals moderately strong and close serially, between the rows and the 
dorso-centrals there are a few scattered hairs; bristling of pleurae and 
scutellum normal. iVhdomen longer than thorax, broad at base, slightlj^ 
ta|)ering to apex; sixth segment very distinctly elongated, in type equal 
in length to the 3 i)receding segments ; apices of all segments with distinct 
bristles; hypopygium large, projecting slightly le.ss than length of sixth 
segment, surface with numerous hairs; last ventral segment with lateral 
jiroce.sses as in bispina hut not so long nor broad ; the protruding recurved 
process small, weakly haired. Legs normal in shape; all tibiae wuth 
preapical bristle; hind femur without any prcapical postero-ventral 
bristle; hind tibiae not noticeably haired ; surfac(^s of legs with the small 
hairs rather distinct. Wing venation as shown in Fig. 12. Length, 
3 mill. 
Type. —Urhana, Illinois, IMay 9, 1S91 (C. A. Hart). 
Female.—i^hmhu' to male in color and chaetotaxy. The abdomen is 
broadly ovate, the segments slightly decreasing in length to apex, the 
ajiical one rather longer than snhapical; all .segments with distinct ajiical
