116 THE ENTOMOLOGIST. 
Celioxys sanguinosus, Cockerell. 
Guacimo, Costa Rica, June 21st, 1908, one female (J. C. 
Crawford). U.S. National Museum. The last ventral segment 
has a well-defined tooth-like apex, whereas the type has only a 
nodule, but the specimens are evidently conspecific. 
Celioxys azteca, Cresson. 
San José, Costa Rica, May 81st, 1903, ‘‘on orquetilla,” one 
female (J. C. Crawford). U.S. National Museum. 
Celioxys texana sonorensis, subsp. nov. 
3. Length about 84 mm.; face densely covered with white 
hair; first two joints of antenne dark red, the others black ; hair on 
eyes shorter than in male terana from Wisconsin ; region surround- 
ing middle ocellus strongly elevated ; mandibles with a red subapical 
spot; cheeks thinly covered with white hair, more densely below 
(texana from Wisconsin has a large bare space, wholly wanting in 
sonorensis) ; mesothorax closely and very coarsely punctured; two 
conspicuous spots of creamy hair on anterior margin, and a thinly 
hairy triangle between; scutellum densely punctured, the hind 
margin with pale hair, and not tuberculate or angular; tegule clear 
bright ferruginous ; first r. n. joining second s. m. at extreme base ; 
legs bright clear ferruginous, the tarsi strongly dusky; spurs clear 
red; abdomen clouded with red at sides and beneath; apical segment 
deeply excavated, with three teeth on each side, but one of them 
more or less bifid, no median tooth; fourth ventral segment with two 
red teeth on apical margin, not extending beyond the fringe of white hair. 
Hab. San José de Guaymas, Mexico, April 10th (L. O. 
Howard). This insect has caused me some perplexity, because, 
except for the smaller size, it agrees fairly well with Cresson’s 
brief account of male texana. It is certainly quite distinct from 
the Wisconsin insect which Dr. Graenicher has sent me as 
tecana; but Dr. Graenicher’s female, which certainly seems to 
belong with the male, appears to be veritable texana as described 
by Cresson. Dr. Howard’s bee has the appearance of a desert 
insect, and should be distinct from the Texan species, which 
may well range into Wisconsin. Very possibly the new form 
represents a distinct species, C. sonorensis, but until it is com- 
pared with the type of texana it may be given only subspecific rank. 
In my table of male Celioxys in Canadian ‘ Entomologist,’ 
C. sonorensis runs to C. quercina, Ckll., differing by the absence 
of a median process at end of abdomen, the rounded (instead of 
squarely truncate) hind margin of scutellum, the red colour at 
sides of abdomen beneath, and the smaller size. It is allied, 
however. 
Celioxys otomita bicarinata, subsp. nov. 
?. Exactly like C. otomita, Cresson, except that the clypeus has 
on its lower two-fifths a pair of parallel longitudinal ridges, with a 
depression between.
