plant surfaces. This is evidently effected by the chorion in whole or 

 part, probably including the vitelline membrane. (Pages 131, 132,. 

 133, 134.) 



The Myiophasiine flies are parasites of weevil grubs in buds as well 

 as fruits, as for example cotton buds (squares) and doubtless buds of 

 other plants. (Page 136.) 



It seems probable that the Cuterebrine flies have a uterus in which 

 the eggs are partially incubated. The hinged lid of egg is at the 

 cephalic end. (Page 137.) 



The piercer-like organ of the female of Emphanopteryx is probably 

 functional in piercing the skin of the host, but this has yet to be 

 demonstrated. (Page 140.) 



Celatoria probably has the piercer and larvipositor as separate 

 organs. (Pages 140, 141.) 



Phasiatacta has the chorion with alveolae (not areoles) gathered 

 around a dorsal opaque area. (Page 144.) 



Pyrrhosia evidently can not go in the tribe Eumyobiini, since 

 Pantel has shown that it has the eggs and maggots regularly arranged 

 in the uterus. (Page 147.) 



Certain of the above points are brought out fully in the paper 

 referred to as reviewing Pantel's results, besides many other important, 

 points in connection with the subject. 



A certain number of the series given represents subfamilies, but the 

 great majority corresponds to tribes. Each series name given in the 

 paper should have the final "E" changed to "I" and serve as the 

 name of a tribe, each tribe taking as its type the type species of the 

 genus from which its name is derived. At least seven families and 

 twenty subfamilies should be recognized in the Muscoidea on the basis 

 of our present knowledge, but it is premature to attempt to define 

 these at present, for further knowledge of the many forms yet to be 

 investigated will quite certainly modify our present conceptions. 



The article in "Science" on "Muscoid and especially Tachinid 

 Synonymy" appeared in the issue for June 2, 1011. This and the 

 forthconmig review of Pantel's 1910 paper, which review also includes, 

 correlation of results secured by Portchinski a quarter-century ago,, 

 taken with the present corrections and the paper to which they refer, 

 will present a fairly complete general statement of the progress of this, 

 work up to the early part of the present year, so far as known to me. 

 Further and more extended papers are in preparation.
