 distended. The gHMu'ral (■ok)r of the adults is reddish, usualh' more or 

 less tinged with yelh)wish or orang-e, and most specimens have a dark 

 spot on each side, due to the food contents of the body, from which 

 the scientific name l)hiiacu1(if>ix (two-spotted) has ])een derived. 



Careful study of ditl'erent individuals as they occur on garden vege- 

 tables and horticultural and other plants grown out of doors with 

 those taken in greenhouses shows no appreciable ditlerences. Accord- 

 ing to Mr. Banks, however, specimens taken in Florida on Datura and 

 at Washington, D. C, on violets are red, while those from Orono, Me., 

 and those from the District of Columbia on squash and peaches, and 

 those on rose from Idaho, are greenish with more or less dark 

 markings. 



The eggs are extremely minute, spherical, of variable diameter, 

 glassy, and are scattered and loosely attached about th(^ webs. 



The young are of somewhat similar appearance to the adults, l)ut 

 differ in having only three pairs of legs. 



DlSTmBUTTON. 



If, as seems probable, Tvtram/cJius cucvineris or some other species 

 descril)ed l)y Boisduval (Entom. Horticole) is identical with the present 

 species of red spider, it is (piite likely that it is of foreign origin and 

 introduced into the United States, which is true of a very large pro- 

 portion of greenhouse and other indoor insects. 



The two-spotted red spider is well distributed through the eastern 

 United States, and has been identified as occurring in localities as far 

 west as Idaho. A list of localities from which the species has been 

 reported includes Orono, Me.; Ithaca and New York City, N. Y. ; 

 Westgrove, Pa.; Washington, D. C. ; Tremont, Pekin, and Blooming- 

 ton, 111. ; Punta Gorda, Key Largo, Gallowa3% and Eustis, Fla. ; Charles- 

 ton, S. C. ; Auburn, Ala. ; and Weiser. Idaho. 



RECENT IN.TTTKTES. 



During the past two years we have received complaints of this spe- 

 cies from various sources, as follows: 



June 9, 1899, from Mr. H. M. Simons, who reported its occurrence 

 on snap beans grown at Charleston, S. C. The species was stated to 

 have literally overrun and totally desti"oyed the 1)eans where discovered. 

 It had not been s(mm\ in previous years, and it was noticed that the 

 season had been very dry. 



Jul}" 6 the occurrence of this red spider was rei)(>rt(Hl by Mr. E. S. 

 Earle on cowpea and l)eans at Auburn, Ala. 



May S, 1900, it was concerned in injury to raspberry at Blooming- 

 ton, 111., and reported to this office by Mr. J. L. Lampe, ji'.
