184 THE CANADIAN ENTOMOLOGIST. 



joints subquadrate, small, the first funicle joint smallest, joint six largest, 

 four times or more larger than the first ; all funicle joints short, the distal 

 joint alone longer than wide ; funicles two and three subequal, four and 

 five subequal, the latter twice the size of the former, each taken separately, 

 six over twice longer than four or five. Club long, accuminate-ovate, as 

 long as the whole funicle, or very nearly, subequal to the scape; obtusely 

 pointed. 



From two specimens, ^-inch objective, i-inch optic (Bausch and 

 Lomb. ) 



Male. — Unknown. 



A species unique for this group because of its antennal structure. 

 (See the figure in its original description.) Black, with a yellowish band 

 about the base of the abdomen. 



Described from a single female specimen found in the collections of 

 the United States National Museum, Washington, D.C., labelled "Ex ovo 

 Codling Moth, Tallapoosa, Ga." Remounted in balsam from a tag. 



Also another specimen captured on the window of an old pig-shed 

 on a farm at Centralia, Illinois, August 25, 1910 (A. A. Girault). The 

 species must be widely distributed in the United States. 



Habitat : United States — Tallapoosa, Georgia ; Centralia, Illinois ; 

 Washington, D. C. 



There is a specimen in the U. S. National Museum collection and one 

 in the collections of the Illinois State Laboratory of Natural History, 

 Urbana, Illinois. (Accession No. 42,221.) 



MIASTOR LARV.E. 



These remarkably interesting larvae, reproduced by pedogenesis, are 

 available for laboratory work to a marked degree and must be widely 

 distributed as well as allied forms. Very little is known concerning 

 American species, largely because their habitat is one rarely explored by 

 entomologists. They breed mostly in decaying vegetable matter. We 

 have been very successful in finding them under partially decayed chestnut 

 bark of stumps, fence rails and sleepers which have been cut one or two 

 years earlier. European species have been observed under the bark of a 

 variety of trees and even in sugar-beet residue. These Dipterous maggots 

 with diverging antennae have a flattened, triangular head, quite different 

 from the strongly-convex, usually fuscous head of the Sciara larvae occur- 

 ring in a similar environment. They have a length of from 1/20 to 1/8 of
