definitely determined by the males, the other sex can be more intelli- 

 gently studied and that will no doubt result in the discovery of some 

 satisfactory characters of differentiation. The species of Sarcophaga 

 are for convenience divided into eight groups which are fairly well 

 defined. A table of species is given which is very practical, simple and 

 explicit. Considering the obscurity in which the species of this family 

 have been existing, the ease with which the species can be run out, 

 even within at least two or three without considering the genitalia, seems 

 almost incredible. 



Another commendable feature is the consecutive numbering of all 

 the species treated and giving the same number to all figures relating 

 to each respective species. Although this adds some confusion to the 

 sequence of the numbers appearing on the plates in the cases of the 

 species not figured, this disadvantage is trivial in comparison to the 

 convenience it gives in working with the paper. 



As to adverse criticism, I do not care to enter this phase of the 

 subject at this time. The excellency of the work in its usefulness will 

 far outweigh its defects. I must say, however, that I do not approve 

 of the typography of the paper. There is too much monotony in the 

 style of composition as one turns over page after page. With a few 

 exceptions there are no catchy divisions between the description, notes 

 and habitat data. The method of citing habitat data might certainly be 

 improved. The use of the parentheses is not consistent. Sometimes 

 they may include the name of the collector or, again, may include the 

 name of the town of a State. In working over the tables I noticed what 

 is evidently a slip of the pen, on page 67. Table of species of Group A, 

 I, should read: Middle femur with . . . (not Middle tibia with 

 . . ). The use of the term bristle is sometimes misleading. On 

 the face the hairs may be described as bristles while in another species 

 those of the same size and stoutness may be described as hairs. The 

 same will apply in some cases to the hypopygium. 



In conclusion I wish to express my appreciation of the work as a 

 whole, and I trust the author will continue to give us this kind of 

 work, which is certainly needed in other groups of the Diptera. E. T.
