ally ; the other, found in the United States, produces males. A colony of what 

 is apparently the male-producing race has been found in England. Fertilized 

 eggs give an equality of the two sexes."

C. G. Hewitt (Canada Dept. Agr., Rpt. Dominion Ent., 1915, pp. I/O, pi. 1, figs. 

 6). — This reports briefly the work of the year under the headings of adminis- 

 tration of the Destructive Insect and Pest Act, and insects affecting cereals and 

 other field crops, fruit crops, forest and shade trees, domestic animals and 

 man, and the garden and greenhouse. A map showing the distribution of the 

 brown-tail and gipsy moths In 1914 and the places in Canada where parasites 

 and predacious beetles have been distributed to date is appended. 



Annual report of the entomolog-ist, A. H. Ritchie (Ann. Rpt. Dept. Agr. 

 Jamaica, 1917, pp. 28-34; abs. in Agr. News [Barbados], 16 (1917), Nos. 401, 

 pp. 282, 283; 402, pp. 298, 299). — The occurrence of the more important insects 

 of the year ended March 31, 1917, is reported upon under the headings of sugar 

 cane, coconut, citrus, pimento, pineapple, storage, corn, truck crop, stock 

 pests, etc. 



The West Indian sugar cane leaf hopper (Stenocranus saccharivorus) was the 

 most important cane pest worked with. Two new host plants, the mahwa tree 

 (Bassia latifolia) and the wampee (Clausenia wampi), are recorded for the 

 spiny white fly (Aleurocanthus woglumi), which has spread throughout Jamaica 

 since its discovery in 1913 and is a most serious pest of citrus. 



Insect pests in British Guiana in 1916, H. W. B. Moore (Abs. in Agr. 

 News [Barbados], 16 (1917), No. 4OO, pp. 266, 267).— A small undetermined 

 pyralid moth borer of the subfamily Phycitiuse, discovered in 1916 and appar- 

 ently new to science, has a wide distribution in British Guiana. The shoot is 

 attacked in a manner quite different from that by the other small borers. As a 

 rule it bores straight to the heart and then merely eats out a small cavity 

 instead of making a longitudinal tunnel. Notes are given on the small moth 

 borers (Diatnea saccharalis and D. canella), which do considerable damage, the 

 large moth borer (Castnia licus), the small black hardback (Dyscinetus biden- 

 tatus), the froghopper (Tomaspis flavilatera), etc.
