)92 THE CANADIAN ENTOMOLOGIST 



It is rather small, with the light hair very pale; mcsolhorax more 

 closely punctured, the brown marks on its anterior part faint and 

 suffused; dark marks of abdomen paler the spots dilute brownish, 

 evanescent posteriorly; second segment with a black dagger- 

 like mark in middle, but the dark basal area so reduced as to be 

 almost entirely overlapped by the first segment. 



Tniepeolus ponionalis, n. sp. 



cf. — Black, with the usual markings on thorax and abdomen 

 warm ochreous, the band oh sixth abdominal segment creamy- 

 white; legs, antenna' and teguhe black. Length about 12 mm.; 

 robust. Superficially, this looks almost exactly like E. remigatiis 

 Fabricius, from Virginia, but it differs as follows: mesothorax 

 anteriorly with two well-developerl longitudinal bands, longer 

 than in remip^alus (these joined, as in remigatns, with the band 

 surrounding mesothorax except in middle of front); median l)lack 

 area on first segment pointed at sides; apical plate of abdomen 

 much larger; insect distinctly more robust. There is also a close 

 resemblance to T. concolor Rob., from Illinois, but T. pomonalis 

 differs thus: clypeus with no median ridge; light hair of face limited 

 to a certain amount on clypeus and lower part of supradypeal 

 area, and a large band on each side of antenna^; bare part of pleura 

 very densely punctured all over; a continuous hair-band all round 

 mesothorax except in anterior middle; black area on first abdominal 

 segment not sharply limited at sides; abdominal bands much 

 broader; apical plate much larger From T. texanus var. nigripcs 

 it is known by the clypeus, which is densely minuteU' punctured, 

 and has scattered larger punctures, which are shallow. T. siiperbiis 

 (Pro\ancher), described from Los Angeles, I have never seen, but 

 T. pomonalis differs from the description in being larger, with 

 no spot on tegula?, stripes on mesothorax too large to be described 

 as "two little lines," and no spots at sides of metathorax. The 

 middle of the abdomen beneath has two silvery-white bands close 

 together, the first with more than the middle third missing; on 

 outer face of middle tibiic anteriorly is a small band of orange- 

 fulvous glittering hair; the wings are very dark; there is pale hair 

 along the border of metathoracic enclosure.
