25 In a row. Beginning on the second tergite, there is a broad 

 transverse band of subchitinized, shagreened texture; on the second 

 to fourth segments they are subbasal, but the last two are on the 

 ends of the segments, one on the fourth, the last on the fifth. The 

 fifth and sixth tergites have the setigerous punctures quite abundant 

 and scattered, except on the basal third, which is bare. The seventh 

 segment bears four obtuse indistinct lobes, two on either side of the 

 median line. The eighth tergite is rounded, with a deep median 

 notch. The eighth sternite shows the genitalia within, consisting 

 of lobes that bear from 12 to 15 strong chitinized points on the 

 inner caudal face. The four basal sternites are hidden by the 

 elongate leg-pads; the sixth with a sub-basal ring of the shagreened 

 appearance described above, the abdomen beyond this ring is pro- 

 vided with numerous scattered hairs, in front of it without hairs. 



Mouth parts, wings and legs, rather dark brown. The thoracic 

 dorsum and abdomen are rather light yellowish brown. The pro- 

 notal breathing horns are very conspicuous, dark brown basally, 

 passing into a bright light yellow on the apical third or quarter. 

 The mesonotal praescutum retains its light coloration even in old 

 pupae and those preserved in alcohol. 



Length: Total, 6.4-7 mm. 



Dextro-sinistral wicith at the wing-pad: 1.2-1.3 mm. 



Dorso-ventral depth at the wing-pad: 1.2-1.6 mm. 



Larva and pupa described from material preserved at Ithaca, 

 N. Y., on October 15, 1912.
