the larval skin not being shed, !nit becoming the outer covering of 

 the puparium, the process being completed in about 36 hours. The 

 pupal period generally lasts for about nine months, beginning some 

 time in August, it being in this stage that the insect hibernates. There 

 is only one amiual brood, though in warmer parts of the country and 

 at lower altitudes it is ciuite probable that C. glabra is double-brooded. 

 It is certain that C. glabra is by far the most effective insect enemy 

 of Pemphigus betae, the worst pest of sugar-})eet in Montana, its larvae 

 acting as a very important check and in many instances destroying 

 entire colonies.

The species dealt with in this paper include : — Thecodiplosis cockereUi, 

 sp. n., widely distributed in Colorado and forming irregular enlarge- 

 ments of the needles of Pinus ed/alis ; Mycodiplosis packardi, sp. n., 

 and Retinodijdosis albitarsis, sp. n., reared from Pinus strobus infested 

 with Parharmonia pini.

Corythuca essigi, sp. n., a Tingid or lace-bug infesting maize {Zea 

 mays), the leaves of which are injured by both nymphs and adults, 

 is here described. An allied species, C. dislincla, 0. & D., has been 

 recorded in Montana upon maize, lettuce, parsnip, beans, lupins, 

 turnip, squash and Bulsamorrhiza, and in Utah upon Carduus 

 lanceolatcs.

Cocoons taken from a nest of the apple tent caterpillar [Mahcosoma 

 americana] proved to be those of Amorphola orgyiae. How., and the 

 parasite reared from them Ofacustes perilifi, Ashm. Both these 

 species have previously been recorded as parasitising Hemerocainpa 

 lencostigma, S. & A.

An infestation in the spring of 1918, which reached a maximum at 

 the end of April, proved to be due to Eleodes Iricostata [see this Review, 

 Ser. A, vi, p. 307]. The injury caused by the larva, while generally 

 resembling that of cutworms, also consists in the cutting off of the 

 buds and leaf-stalks of large plants. The crops most severely attacked 

 are :- Radishes, cabbages, onions, tomatoes, potatoes, maize, and 

 sugar-cane. 



Most gardeners have been satisfied wth the results obtained from 

 the use of poisoned bran mash, Paris green giving better results than 

 lead arsenate. The adults may be found in old or heavily pastured 

 j&elds, from two to a dozen or more under each pile of dry manure, 

 giving rise to the idea that this pest may be introduced with barnyard
