plantations, and has since been reported by Hendricksen and by Tower as a 

 pest in orange groves. The injury caused by this root borer is serious in re- 

 stricted areas. The author observed the adult weevil feeding upon the leaves 

 of sugar cane and in several instances upon the leaves of Spondias hitea, used 

 as fence posts about sugar cane fields. 



The larvae of a rhinoceros beetle, the identity of which has not yet been 

 determined but is thought to be Htrategus titanus, recorded from St. Croix (E. 

 S. R., 28, p. 256) and Jamaica, where it is a pest of sugar cane, and which was 

 also recorded from Porto Rico by Stahl in 1882, have been found breeding at 

 the roots of cane on the southern coast of the island and are a source of injury. 



Several si^ecies of entomogenous fungi were found attacking some of the 

 injurious sugar cane insects. The Hawaiian fungus Metarrhizium anisopliw was 

 found to attack both the adult May beetles and their white grubs, also the larvae 

 of the rhinoceros beetle. Observations indicate that this fungus was established 

 on the island naturally previous to its intentional introduction from Hawaii.

 A list of some 21 pests and their natural enemies. 



Report on a trip to Demerara, Trinidad, and Barbados during the winter 

 of 1913, G. X. WoLCOTT (Porto Rico Sugar Producers' Sta. Bui. 5 [English Ed.}, 

 pp. Jt1-68). — In reporting observations made during his trip the author first 

 discusses cane cultivation on the several islands visited. This is followed by a 

 detailed report upon sugar cane insects in each island, and their parasites and 

 predators, and insect pests of cane growing in the islands whose introduction 

 into Porto Rico should be prevented. 



Report on a trip to Demerara, Trinidad, and Barbados during the winter 

 of 1913, G. N. WoLCOTT (Jour. Boon. Ent., 6 (1913), No. 6, pp. U3-457).—The 

 data here presented are noted above. 



Insect pests at St. Croix (Agr. Netcs [Barbados}, 12 (1918), Nos. 302, p. 378; 

 303, p. 394). — This account from the report of the director of the department 

 of agriculture at St. Croix for the year ended June 30, 1913, deals chiefly with 

 the insect pests of sugar cane and cotton. 



The most important pest of sugar cane is the rhinoceros beetle Strategus 

 titanus. The pink mealy bug is of frequent occurrence and a source of con- 

 siderable damage to sugar cane, especially to the young canes. The moth borer 

 was also a serious sugar cane pest. The weevil borer (Sphenophorus sericeus) 

 occurs in the cane fields each season; a large longicorn beetle (Lagochirus 

 araneiforniis) has been discovered boring in canes at the experiment station. 



The cotton pests at St. Croix are said to be largely the same as those occur- 

 ing in the adjoining islands of the Leeward group, namely, the cotton worm 

 (Alabama argillacea) ; the cotton bollworm ; several other lepidopterans, the 

 caterpillars of which attack the flower buds and bolls, namely, Prodenia orni- 

 thogalU, P. latifascia, and two undetermined species; the green leaf bug 

 CNezara viridula) ; the leaf footed plant bug (Phytoglossus gonandra) ; the 

 cotton stainer (Dysdercus andrece) ; and the leaf blister mite (Eriophyes 

 gossypii). 



The scarabee (Cryptorhynchus hatatw) attacks potatoes in all parts of the 

 island ; Indian corn is seriously attacked by the corn ear worm and the so-called 

 corn fly or leaf hopper (Dicranotropis maidis). 



New insect enemies of carnations in the vicinity of Antibes, E. Molinas 

 (Jour. Agr. Prat., n. ser., 25 (1913), Nos. 21, pp. 654-657, figs. 3; 23, pp. 717, 

 718, figs. 2; 26 (1913), No. 27, pp. 23, 24). — Three new pests, a microlepidopteran 

 (Tortrix pronuhana), a noctuid (Brotolomia meticiilosa) , and a hemipterau 

 (Aphrophora spumaria) are said to have been the source of injury to carna-
