 Washington, D.C., Bull. no. 422, 2nd October 1916, 7 pp., 3 figs. 



Cassida paUiduh, Boh. (the egg-plant tortoise beetle) was observed 

 in injurious numbers in the larval stage in the spiiug of 1915 on the 

 foliage of young egg-plants and potatoes at Baton Rouge, Louisiana. 

 This beetle is somewhat widely distributed over the southern portion 

 of the United States and also feeds on wild species of Solanum. The 

 eggs are usually found singly on the under-surface of the leaves. They 

 were first noticed in the fields on 11th May and were present as late as 

 September. The period of incubation in the insectary during June 

 averaged four or five days. The larval stage, in the insectary, averaged 

 17 days, while that of larvae caged on egg-plants in the open was 12 

 days. The pupal stage in the insectary averaged four to five days. 

 The adult, which also attacks the foliage, lives in summer for several 

 weeks and has been observed to survive for a considerable period after 

 oviposition. The winter is passed in this stage. Under favourable 

 conditions, it is possible that as many as five generations may occur 

 during the year. This beetle is attacked by an undetermined egg 

 parasite. Spraying infested plants with arsenate of lead or arsenite of 

 zinc in the proportion of 1 pound of powder to 50 U.S. gallons of water 

 gave satisfactory results. 



A bibliography of eight works dealing with the pests of the egg-plant 

 is appended.

Pseudococcus citrophilus, Clans., is unusually abundant in the San 

 Francisco region, attacking a large number of plants. At the Mission 

 San Jose the fruit, leaves, limbs and trunks of oranges and lemons were 

 found to be covered with the egg-masses and colonies of this scale, 

 which has also been reported from Pasadena. This species is as serious 

 a pest as the citrus mealy bug [P. citri, Riss.] and should be controlled 

 in the same way.

The Agromyzid fly described in this article was originally believed 

 to be identical with the parasite described by Williston in 1888 as 

 Cryptochaetum {Lestophonus) iceryae, but has recently been identified 

 by Mr. F. Knab as C. monophlebi, Skuse. It is common in many parts 

 of California and at times becomes very abundant. It appears to be
