1913] Brues — A Xcir Species of Phoridce from New England 91 



in addition to one long terminal spur; hind tibia with three bristles, one at basal 

 third on outer edge, one just before middle on the front side and one just 

 before tip on front side in addition to two apical spurs: in addition the hind tibia 

 is transversely striated on the hind (i. e., inner, as the leg folds next to the body) 

 side near tip. Wings yellowish, the veins yellowish brown: costa not thickened, 

 reaching almost two-thirds the length of the wing, its bristles very short and dense; 

 third vein very finely bristly as far as the fork; first vein ending midway between the 

 humeral cross- vein and the tip of the third; second vein lying very close to the third, 

 from which it emerges at a very slight angle; fourth vein curved strongly at base 

 but straight beyond and faintly recurved at apex, ending at the wing tip; fifth and 

 sixth slightly sinuous; seventh distinct. Halteres clear yellow. 



Described from three females sent to me for identification by Mr. 

 C. W. Johnson. Type from Kingston, R. I., May 7, 190.5. Para- 

 types: Riverside, Mass., May 20, 1905; Hampton, N. H., May 10, 

 1905 (S. A. Shaw). Type in the collection of the Boston Society 

 of Natural History. 



This species resembles C. variabilis Brues from Colorado and 

 Washington more closely than any other described species and 

 may possibly be only a well-marked form of variabilis. However, 

 the halteres are pale, there is much more of the orange color on the 

 abdomen, and there are only two supra-antennal bristles. From 

 C. thoracica it differs by the non-thickened costa and from other 

 related species in the chsetotaxy of the tibiae. 



MUSCOID PARASITES OF THE COTTON-STAINER AND 

 OTHER LYG.EIDS. 



By Charles H. T. Townsend. 

 Lima, Peru. 



The only muscoid parasites of Lygceidce so far known in any 

 stage have come to light in Sicily and Peru. The number of species 

 has now reached four, one of which has been reared to the acult. 

 The finding of these may be taken in chronologic order. 



1) Neilsen mentions finding what was probably a muscoid mag- 

 got (Snylteflueart) in the abdomen of an adult of Lygceus saxatilis 

 Scop, in Sicily. The fly was not reared. The species may have 

 been a Clytiomyia (recorded from Sardinia), Eliozeta, or Elomya 

 (Ananta), less likely a Xysta, Cistogaster, or Besseria. 



2) The next finding of muscoid maggots in Lygaeids was by
