556 EXPERIMENT STATION EECOED. 



(1900), pt. 1, pp. 111-115, figs. 17). — ^A study of the orthoptera, based upon 

 field work during the summer of 1907 at stations extending from El Paso, Tex., 

 and Albuquerque, N. Mex., to southern and northern California. In part 1 are 

 presented the results of work in Arizona, and in part 2 the results of work in 

 New Mexico and western Texas. A number of species are described as new 

 to science. 



A catalogue of American aquatic and semiaquatic hemiptera, G. W. Kirk- 

 ALDY and J. R. de la Torre Bueno {Proc. Ent. Soc. Wash., 10 (1908), No. 3-^, 

 pp. 173-215). — This catalogue is intended to include everything published be- 

 fore July 1. 1908. 



Observations on some hemiptera taken in Florida in the spring of 1908, 

 E. P. Van Duzee (Bui. Buffalo Soc. Nat. ScL, 9 (1909), No. 2, 2)p. U9-230, figs. 

 6). — In this paper 354 species of hemiptera representing 203 genera taken 

 during a 4 'weeks' collecting trip in Florida in the months of April and May are 

 listed. Two genera and 29 species are described as new to science. 



The life history and habits of the woolly aphis, W. E. Collinge (Jour. 

 Cooper Research Lai)., 1909, No. 1, pp. 28-87, figs. 3).— An account of Schizo- 

 neura lanigera to which is appended a bibliography of 17 titles. 



A new coccid of the genus Eriococcus, T. D. A. Cockerell (Proc. Ent. Soc. 

 Wash., 10 (1908), No. 3-.'t, pp. 167, 168). — The subspecies Eriococcus quercus 

 gilensis, taken from twigs of Quercus toumeyi at Bellevue, Ariz., is here de- 

 scribed as new to science. 



A new gall-making coccid on Atriplex, T. D. A. Cockerell and S. A. 

 Rohwee (Proc. Ent. Soc. Wash., 10 (1908), No. 3-4, pp. 169, 170).— A coccid 

 taken from Atriplex canescens at Las Cruces, N. Mex., and Trinidad, Colo., is 

 here described as representing the new genus and species, Atriplicia galUcola. 



A moth larva predatory upon the eggs of the bagworm, A. B. Gahan 

 (Jour. Econ. Ent., 2 (1909), 3, pp. 236, 237). — The larvje of Dicymolomia juUanis 

 have been found to feed upon the eggs of the bagworm. In one instance two 

 larvae were found in the same bag. In every case where a full grown larva 

 was found the eggs of the bagworm had been completely destroyed. 



" When full grown the larva crawls out of the egg case and proceeds to spin 

 a small cocoon at the tip or free end of the bag, within which it changes to a 

 pupa -re in. in length and of a clear pale red color. That this predatory 

 moth constitutes a considerable check on the bagworm in this locality can 

 not be doubted when it is known that in some cases 25 to 30 per cent of the 

 female bags were infested." 



The normal habit of the species as heretofore understood was to live as a 

 scavenger in the heads of the common Typha or cat-tail. The issuance as 

 images as early as April or May precludes the possibility of the larvie of this 

 generation feeding on the eggs of the bagworm, and clearly indicates that there 

 must be another host to carry it through the summer. A small chalcidid 

 (Leucodesmia typica) reared from the bagworm is in all probability a parasite 

 of this predaceous moth. 



The larva of Lerina incarnata, H. G. Dyar (Proc. Ent. Soc. Wash., 10 

 (1908), No. S-ff, pp. 162-164). — The larva of this moth, a technical description 

 of which is given, feeds upon Asclepias puniila. 



Chironomid larvae living in leaves, V. Willem (Acad. Roy. Belg., Bui. CI. 

 Set., 1908, No. 8, pp. 697-704, pi. i),.— The author reports finding the larvse of 

 Chironomides sparganii n. sp., and another species in the leaves of Sparganium 

 ramosum, the larvse of Psectrocladius stratiotis n. sp., in the leaves of Strati-
