 not interstitial but joining the first submarginal cell at the lower apical 

 angle ; first abscissa of radius about half the length of the second. 

 Abdomen ferruginous or reddish-yellow,' the first and second segments

 the basal part of the third segment, as well as the first two, is also 

 shagreened.

Bred Sept. 14, 1891, from a Buprestid, or Longicorn, larva living 

 under bark of dead Spruce Abies nigra. 



I am doubtful about the position of this insect, as it might just as 

 well be placed in the genus Doryctes as in RJiysipolis, having a close 

 resemblance to Doryctes radiatus Cr., D. macilentus Prov., D. fartus 

 Pro v., and other species in this genus.
