Perkins, Bui. 1, pt. 1, Exp. Sta. Hawaiian Sugar Planters' Associ- 

 ation) . Perhaps the Rhopalosomidae and the Dryinidae had a com- 

 mon origin, as the larvae would indicate, and the adults have spe- 

 cialized along different lines though retaining certain characters 

 in common. 



It may be interesting to add that the family Rhopalosomidte 

 is now represented by four species, one of which has been placed 

 in a genus of doubtful standing. Three species have been reported 

 only from the Neotropical region, and one which is known to occur 

 in India and Ceylon from the Oriental region. The Rhopalosonm 

 poeyi Cresson was originally described from Cuba but since has 

 been reported from Jamaica; San Domingo; Hayti; St. Louis, 

 Missouri; North Carolina; St. Augustine, Florida; Louisville, 

 Kentucky; and now from the environs of Washington, D. C. Lest 

 some marvel at this remarkable distribution it may be added that 

 great care was used in making the determination of Mr. Hood's 

 specimen and unless there are characters which have escaped both 

 Ashmead and myself this species has the wide distribution given 

 above. An excellent figure of this species is given on plate 24 

 (figure 9) of Thesaurus Entom. Oxon. 1874. 



NOTES ON THE FEEDING HABITS OF TWO ADULT SAWFLIES. 



BY S. A. RomVER, Bureau of Entomology. 



The feeding habits of adult sawflies are very incompletely known, 

 although a few European species have been observed feeding either 

 on the pollen of plants or on certain insects. From the literature 

 which has been published on this subject it is a rather accepted 

 opinion that the species of TenthredeUa and Tenthredo feed, in the 

 adult stage, on other insects. The following observations will 

 show that this is not always the case. As far as I have been able 

 to learn the records refer to feeding habits of the female only. Do 

 the males feed? 



TENTHREDELLA LINEATA ( 



On July 4, 1907, I found a female of the species devouring an 

 adult Perlid which has been determined by Mr. Banks as All<> i>cr In 

 signata Banks. The adult sawfly was sitting on the foliage of 

 Heradeum lanatum.
