 uella, described elsewhere in this paper. Moths issued May 11 (1915).

An easily recognized species. The legs seem a trifle short for a 

 Podosesia and are not so roughly scaled as those of syringae orfra^ini 

 but it has the characteristic palpi and belongs quite unmistakably to 

 that genus. Tiiere is also a queer freak in venation in the male; 

 3 and 4 of the hind wing are distinctly separate. In the female they 

 are stalked. The forewing of tlie male also has 7 and 8 somewhat 

 shorter stalked than the female. Whether these differences are con- 

 stant between the sexes I can not say as only two specimens were 

 reared. 



The larva is white with anal and thoracic shields nearly the body 

 color, only slightly more yellow; a narrow transverse, irregidar, and 

 indistinct light brown line on each side of middle of dorsum on tho- 

 racic shield ; legs yellow with brownish tarsal claws ; crotchets brown, 

 13-16; spiracles light bro^vn, conspicuous; tubercles unpigmented. 

 Head brown, very pale yellow in the posterior regions of the epicra- 

 nium adjacent to the longitudinal ridge; mandibles, mandibular 

 attachments of epicranium and endoskeletal ridges black; frons 

 thickened into a raised knob above the surface level of the epicra- 

 nium, dark b^o^vn; ocellar pigment black in small individual spots 

 under or nearly under the several ocelli. Length, full grovm, 12-13 

 mm. 



The larva is easily recognized by the peculiar elevated frons.

During 1915 a half dozen specimens of this species were reared by 

 Mr. W. Middleton and the writer from material collected at Manitou 

 and North Cheyenne Canyon, Colorado. 



Up to this time the species had not been represented in the 

 United States National Museum Collection and as far as I Imow the 

 food plant and larval habits v:ere unpublished. The larvae are 

 inqueline borers in the woody galls of a Cynipid on scrub white oak, 

 in habit and general appearance very similar to those of S. scitula 

 Harris. Larvae collected during September 1914 by x\. B. Cham- 

 plain (Hopk. U. .S No. 12082m), and April, 1915, by B. T. Harvey 

 (Hopk. U. S. No. 12153c). Moths issued May, June, and July.
