60 THE ENTOMOLOGIST. 



Hah. Copeland Park, Boulder Countv, Colorado. Sept. 4th, 

 1907 (S.A.Rohwer). 



Epeolus hitei, sp. nov. 



2 . Length 7^ mm. ; black, with the usual markings ; liead and 

 thorax densely rugoso-punctate ; head broad, eyes strongly converging 

 below; labrum, mandibles, and first three antennal joints ferruginous ; 

 tegulse, tubercles, tibiae, tarsi and femora at apex and narrowly be- 

 neath, all lively ferruginous ; anterior middle of mesothorax with a 

 rather V-shaped mark of light pubescence ; scutellum bigibbous, 

 extending l)eyond the short lateral teeth ; pleura with a very broad 

 and conspicuous transverse band of light hair, below which it is nude 

 or almost, very densely rugoso-punctate ; spurs reddish-white ; wings 

 with a distinct dusky shade beyond the marginal cell ; stigma ferru- 

 ginous ; abdomen with broad yellowish-white hair-bands ; first seg- 

 ment with a long transverse dark area, and the marginal band inter- 

 rupted in tlie middle. In Eobertson's table (Canad. Entom. October, 

 1903) this runs to tlie neighbourhood of E. autumnalis Rob., but is 

 very distinct from that by the markings of the thorax, larger punc- 

 tures of scutellum, &c. The resemblance is closer to E. heulahensis, 

 CklL, but the thorax is much less hairy than in that species, and the 

 lateral oval spots on second abdominal segment are wholly wanting, 

 while the dark area on the first is not pure black, but is covered with 

 fine golden-brown pubescence.

Sphecodes lautipennis, sp. nov. 

 (? . Length 8 to 9 mm. ; l)lack, with the abdomen red except at 

 liase and apex ; face covered with white hair ; vertex with erect 

 white hair ; mandibles with the apical three-fifths ferruginous ; an- 

 tennge black, flagellum thick, submoniliform ; thorax with white 

 hair, the mesothorax quite hairy, and with strong close punctures, 

 the posterior middle shining and with the punctures widely 

 separated ; middle of scutellum flattened, shining and sparsely 

 punctured ; area of metathorax sharp-edged, and with very strong 

 vermiform plications ; legs black, the small joints of tarsi ferrugi- 

 nous ; tegulae testaceous, subhyaline and punctured in front ; ivings 

 ample, very clear, almost milky, nervures very pale ferruginous, 

 stigma more infuscated ; abdomen parallel-sided but not especially 

 narrow, shining ; first segment very sparsely punctured, second with 

 the apical two-thirds very sparsely punctured, the basal with fine 

 close punctures ; third with the fine punctures extending practically to 

 the subapical groove ; fifth and sixth segments, except apical margin 

 of fifth, black, and a little blackish on the one before ; black on first 

 segment occupying the basal part, except a more or less evident 

 median red patch, the hind margin of this black having two small 

 projections. Fourth antennal joint as long as fifth, and not so long 

 as 2 + 3 ; flagellum without facets beneath. Allied to S. clematidis 

 Rob. ; peculiar for the clear white wings.
