OF WASHINGTON, VOLUME XV, 1913 105 



So far as we observed the larvae live wholly in the roots, and that 

 portion of the root lying within 2 or 3 inches of the surface of the 

 ground is most subject to attack. Transformation takes place 

 within a cocoon, constructed, chiefly of small shreds of plant fiber, 

 which is built up in a longitudinal excavation, made by the larva 

 in one side of the root. About one-third of this cocoon lies outside 

 of the root itself and is in sharp contrast to it because of its much 

 darker color. 



As stated above, all stages, from half grown larvae to the adult 

 beetles were to be found on August 14, and quite a number of the 

 empty cocoons were also to be seen. 



The beetles were evidently present in very great numbers, as 

 practically every root of a Cakile plant that was examined, over a 

 strip of beach a quarter of a mile long, was found to be more or less 

 attacked by them. 



Mr. J. R. de la Torre Bueno exhibited and remarked upon the 

 following insects: 



Neuroctenus simplex Uhl., an Aradid, two specimens of which had 

 mites fastened to the underside of the body, in one case one speci- 

 men on the connexivum, and in the other case two on the meso- 

 sternum, between the legs. The eggs of this species were also shown, 

 fastened in clusters to the inner side of bark. Two clutches were 

 parasitized by a minute Proctotrypid, which showed dark through 

 the corium of the infested ova, and a mounted specimen of this 

 was shown, which flew out from the home of the bug as the bark was 

 lifted. N. simplex is commonly found under the bark of dead oak 

 saplings. The female would seem to brood her eggs, to judge by 

 the actions of two found over the two batches, from one of which 

 the red young were emerging. The actions of the females gave 

 color to the interpretation of maternal solicitude put upon her 

 position with the abdomen extended over the egg masses. This is 

 a very rare phenomenon in the Heteroptera, the best attested ex- 

 ample being the classic instance of the European Cimicid, Rha}>ln- 

 gaster nebulosa Poda (griseus Fabr.) 



A specimen of Sinea spinipes H. S. taken at Yaphank, Long 

 Island, New York, in the pine region of the island. This is the 

 most northern record of this species, described originally from South 

 America and later recorded" from western United States, and here- 

 tofore naturally considered strictly southern.
