scutellum slightly more finely rugose than mesoscutum, the lateral 
teeth rather long and slightly incurved; propodeum and pleurze with 
long white hair; wings slightly dusky with the apical margins somewhat 
more so; spines on anterior coxze long; abdomen with the venter largely 
reddish and the edges of dorsal segments close to venter somewhat 
reddish (to be seen only from below); first segment of abdomen closely 
punctured, the punctures laterad separated by less than a puncture 
width; segment 1 with a basal and segments 1-5 with white apical hair 
bands; segments 2 and 3 deeply and 4 rather shallowly transversely 
impressed; the segments basad of the impressions closely punctured, 
apicad of them very sparsely so; last dorsal segment suddenly angularly 
constricted, and with a median carina (see fig. 5a); last ventral notched 
at sides (see fig. 5b); ventral segments 1-5 with apical hair bands and 
coarsely punctured. 
Habitat: Los Angeles, Co. Cal., (D. W. Coquillett, collec- 
tor). 
Type—Specimen: Cat. No. 18224, U.S. N. M. 
In general this resembles octodentaia but differs in the vertex 
being rugose and without smooth areas, in the rugose meso- 
scutum (in octodentata the punctures on the disk of the meso- 
scutum are well separated); in the abruptly narrowed last 
dorsal segment, and in the closely punctured first segment of 
the abdomen. In this last character it resembles pratiz but 
differs in all the other characters quoted above; pratti has the 
mesoscutum more closely punctured than octodentata but it 
is not rugose. In the shape of the last dorsal segment this 
resembles rufitarsus from which it differs in addition to the 
difference in the color of the legs by the first segment being 
closely punctured, by having the second and third segments 
basad of the transverse impressions more closely punctured 
and by having the fifth ventral, except apex, with coarse 
punctures, etc. 
Ccelioxys insita Cresson. 
The apex of the ventral segment as illustrated and marked 
on the figure is the approximate point to which the last dorsal 
segment comes (indicated by a U in the sketch). (Fig. 6.)
