the inner orbits strongly converge below, which is not the case in 

 ritbriz'cntris, but they agree in the simple mandibles. The mandibles 

 of male L. chalyhcca (Friese) are strongly bidcntate, while those of 

 L. thoracica (Friese) are as strongly tridentatc. In L. thoracica the 

 b. n. almost meets the t. m. Friese, in describing his genus Biglossa 

 {=Lonchopria), did not indicate a type. His first species, thoracica, 

 is hereby designated the type of Biglossa. 



Colletes miminca new species. 



Male. — Length about loj^ mm.; black, head and thorax with abundant 

 long black and white hair ; clear white on face (some black at extreme sides) 

 and cheeks, nearly all black on front and vertex, white on occiput ; on thorax 

 above the hair is mixed black and white, the effect being rather dark grey, on 

 pleura it is largely black; the legs have pale hair, light ochreous on inner side 

 of tarsi ; the abdomen has long greyish-white hair on the first segment, the 

 other segments are rather thinly covered with short, easily abraded, pale 

 ochreous furfuraceous pubescence, and have in addition thin long hair, only 

 clearly visible in lateral view, this hair being white at the base of the second, 

 and slightly on the bases of the third and fourth segments, but otherwise 

 black ; extreme apex with fuscous hair ; no hair-bands ; head very broad ; eyes 

 prominent; antennae black, third joint shorter than fourth, fourth shorter than 

 fifth ; joints of middle of flagellum much longer than broad ; clypeus with a 

 shallow median sulcus ; mandibles bidentate, rufous at extreme tip ; labrum 

 with three strong pits or grooves ; malar space extremely long, more than 

 twice as long as its apical breadth, its length about equal to distance from 

 notch to base of mandible; prothoracic spines not evident; mesothorax and 

 scutellum shining, with numerous small punctures ; area of metothorax with 

 very numerous vertical ridges ; hind basitarsi broadened, rather hollowed on 

 inner side ; tegulae piceous ; wings dusky hyaline ; stigma small, dark rufous, 

 nervures piceous ; second s. m. very large, receiving first r. n. a little beyond 

 middle; b. n. falling a short distance short of t. m. ; abdomen very finely 

 punctured ; stipitcs very broad ; sagittae divergent apically ; hind margins of 

 ventral abdominal segments with narrow dense pale hair-bands. 



Habitat. — Two males, Matucana, Peru, June-July, 1913 {Ernes). 



Superficially, this is exactly like Lonchopria inca. Although the 

 abdomen is not really banded, when worn it seems to be so, owing to 

 the furfuraceous pubescence remaining in the apical depressions of the 

 segments. The species belongs to the C. lycii group, and has some 

 affinity with C. pcriczncus Ckll., but is much larger, with longer malar 

 space, etc. In Swenk's table of North American CoUctcs (1908) it 

 falls closest to C. inlcrmi.vtus.
