A new Sawfly of Economic Importance* (Hymen.). 

 BY S. A. ROHWER, Washington, D. C. 



Some time age Mr. R. A. Cushman, who was at that time 

 stationed at Tallulah, Louisiana, sent to the Bureau of Ento- 

 mology a sawfly which was found defoliating the peaches in 

 that locality. The specimens sent represent a new species be- 

 longing to the genus Caliroa (sub-genus Erio camp aides), and 

 are herewith described. The habits of this species have been 

 studied by Mr. Cushman, and will be described in a paper to be 

 published by the Bureau of Entomology. Mr. Cushman states 

 that they differ in a number of ways from those of the com- 

 mon pear slug, although the larvae and work are superficially 

 similar. 



The accompanying figures were prepared from camera lu- 

 cida sketches, and the description was made with the aid of a 

 Carl Zeiss binocular with a magnification of thirty-five diame- 

 ters. 



Caliroa (Eriocampoides) amygdalina new species. 



Related to C. (Eriocampoides) quercus-coccinca (Dyar), but the 

 frontal fovese are small, well denned, punctiform, not large and poorly 

 defined; the third and fourth posterior tarsal joints have projections 

 beneath; the stigma is shorter; the wings uniformly dark; the trans- 

 verse radius is received basad of the middle of the cell, not beyond the 

 middle ; and the saw has small, separate dorsal teeth, and larger ventral 

 ones. 



Female. Length 3.5 mm. Labrum broadly rounded, granular ; clypeus 

 broadly emarginate, somewhat angular, the lobes broad, triangular ; 

 supraclypeal area convex throughout its entire length, not mound-like; 

 antennal foveae rather small ; middle fovea not sharply denned, large, 

 somewhat circular in outline ; frontal foveset small, sharply defined, punc- 

 tiform; sides of the pentagonal area ridged as in qncrcus-coccinea; ocel- 

 lar basin shallow, circular in outline; postocellar furrow wanting; posto- 

 cellar area twice as wide as its cephalo-caudad length ; antennre hairy, 

 the third joint much longer than the fourth, but shorter than the fourth

t The term "frontal foveae" is used for the fove;e which occur in 

 some species, in the antennal furrows near the frontal crest.
