NOTES ON HETEROPTERA. 



BY J. R. DE LA TORRE BUENO, NEW YORK. 



Near my house in White Plains, N. Y., is a sunken meadow, on one 

 side of which runs a brooklet, and on the other the Bronx Aqueduct, 

 which carries water to New York city. The Tarrytown road bounds it at 

 one end, and the other merges gradually into a marsh which is cut by 

 another brook. In this meadow grows a profusion of plants, each in its 

 season, and here insects abound in all forms. I have taken in it many 

 interesting Heteroptera. Along the edges, at the Aqueduct, Eurygaster 

 alter?iaius occurs. Further on, in the plants growing out of the wetter 

 and lower portion of the meadow, in July and August I found many 

 nymphs ; some I could recognize, but two were misidentified. One was 

 a peculiar spiny one, with an enlarged antennal joint. I guessed it to be 

 Chariesterus a?ite?inator. To make sure, I took several full-grown 

 nymphs home, together with one of Architnerus calcarato?-. The food 

 problem, of course, presented itself, but the solution was found in the 

 remains of my vegetable garden, and a bush bean pulled up by the roots 

 and put in water in a breeding cage gave the nymphs food and shelter. 

 They throve on the bean, and my queer capture turned out to be nothing 

 but Acant/iocerns galeator. This very interesting nymphal form appears 

 to be unrecorded, and Dr. Horvath, who was in White Plains at the time, 

 suggested that it be described. 



In colour it is a checkered grey and black, quite on the dark. This 

 nymph is very spiny. The antennae have the first joint studded with short 

 spines, which in the second joinj: become smaller and are interspersed 

 with hairs. This joint is dark at the base and apex only, the greater 

 portion of the middle being light in colour. The third joint is expanded 

 into a leaf-like form, with the narrowed end at the base of the joint and 

 the broader at the apex. This, as well as the fourth joint, is black and 

 hairy. The latter is fusiform. The first joint is subequal to the second, 

 and the third to the fourth, each of the latter being about two-thirds the 

 length of either of the former. The femora are all armed with stout 

 spines, which are practically obsolete on the tibice. There are six long, 

 toothed spines on the head, arranged in pairs, and one at each anterior 

 angle of the pronotum, the lateral edges of which are also spifiy, and the 

 disk is studded with coarse black punctures. The wing-pads are also 

 spined on the outer edge and coarsely punctured Each of the abdominal 

 segments has at the connexival edge two stout spines, one near the
