Laphria ithypyga new species. 



Scarcely differs from last in general appearance, but male genitalia 

 are very distinct. Hypopygium black, black bristled, straighter than 

 usual in the genus; apical process not twisted, broad, stout, fonning 

 the principal part of apex of forceps; hollowed out within and fonning 

 with lower apical angle of forceps a considerable emargination which 

 is broadest distally. (Fig. 18). Length 12-17 mm. 



Type, male, Harrisburg, Pa., June 18, W. R. Walton, 

 (U. S. N. M.).

Laphria sicula new species. 



Laphria canis, in large part, of previous authors, not of 

 Williston according to the male type. 



Mystax black; face, occiput, coxse, pleuree and usual oblique fascia 

 on front of thorax gray to white pollinose, with hair where present mostly 

 concolorous. Thoracic bristles and tuft in front of halteres black. 

 Sparse pile of thoracic dorsum white, of abdomen black and white, the 

 latter more prominent on sides of posterior parts of segments. Legs 

 with black and white hair. Wings dark fimiose, slightly paler toward 

 base. Hypopygium black with black bristles and a few pale hairs on 

 end of anal valve; forceps from above stout, curved abruptly, tapering 

 to rather acute apex; from side, appearing shallowly emarginate at 

 apex, claspers borne by forceps unusually stout and extraordinarily 

 large at base where inserted in forceps. (Fig. 19). Length 9-14 mm. 



Type male and allotype female, taken in copula, Plummers 

 Island, Md., July 21, 1907, A. K. Fisher, (U. S. N. M.). 



Records for other females of this species are not given for 

 the reason that with present knowledge they are not separable 

 from females of L. canis and of L. winnemana.
