Tachinid parasites, Frontina aleliae, Riley, and Archytas piliventris, 

 Wulp, were bred out and the percentage of parasitism was high. 

 Chloridea (Heliothis) obsoleta, F. (com earworm) seriously damaged 

 maize in some localities, in one iastance 90-100 per cent, infestation 

 of the cobs occurred. The ears were subsequently heavily infested 

 in the fields by Calandra granaria, L., and in one sample Silvanus 

 snrinamensis, L., was most abundant. Diatraea sacfJiaralis, F. (stalk 

 borer) was present in specimens from St. Mary and Clarendon. The 

 destructive wood-boring Bostrychid, Ajxite terebrans, Pall., was noticed 

 attacking Pilhecolohium saman, Cajanus indicus (Congo pea), Persea 

 gratissima (avocado), etc. Caryoborus sp. and Calandra linearis, 

 Herbst, caused considerable damage to the pods of Tamarindus indica 

 (tamarind). Specimens of the fungus, Cordiceps sphecofxphala, 

 Klotzch, growing on, and killing wasps of the genus Polistes, were sent 

 in. The fungus, Isaria barberi, parasitic upon Diatraea sacchiralis 

 was collected at Chapelton. The presence of Cosmopolites sordidus, 

 Germ, (black banana weevil) in the island was recorded in 

 November 1915 [see this Review, Ser. A, iv, p. 175]. From GlengofEe 

 and Spanish Town complaints of infestation of hives by Galleria, 

 mellondla, L. (wax moth) were received.

According to Bellevoye more than 450 species of insects live on the 

 willow. In this article only the most injurioas ones are briefly dealt 

 with. 



Coleoptera : — Melolontha melolontha, Phylloperlha hcMicola, Anomala 

 frischi, Agrilus viridis and Cryptorrhynchus lapathi. The last-named 

 is the most injurious of the weevils infesting the willow. The bark of 

 the branches mined by the larva becomes brown and sphts and the 

 branches themselves break in the wind. All infested branches, whether 

 on the tree or on the ground, should be collected and burnt. The 

 adults may be shaken down on to sheets. The adults of the Longicorn, 

 Saperda carcharias, may be collected in the same manner, while the 

 larva of this beetle, which remains within the trunk and branches for 

 two years, may be killed by closing the holes with plugs soaked in 

 carbon bisulphide, benzine, etc. In the nurseries the young stems may 

 be covered with a mixture of cowdung and clay to a thickness sufficient 

 to prevent oviposition on the bark. The larvae of Lamia textor and 

 Aromia moschata, which resemble those of *S'. carcharias and have the 

 same habits, may be destroyed in the same way, A Chrysomehd, 

 Melasoma {Lino) populi, oviposits on the leaves, which are devoured 

 by the larvae. There are two or three generations annually, the last 

 one hibernating and ovipositing in the following spring. Shaking the 

 insect on to sheets and spraying are the controls advised. Two other 

 Chrv^somelids, Phyllodecta vilellinae and P. vidgatissima, appear from 

 April to July or August. There are two generations a year, the second 

 hibernates and then oviposits in the spring, when the young larvae 

 attack the buds and, later on, the leaves. The beetles may be caught 

 in shelter-traps and then burnt. Against the larvae, dusting with 

 quicklime is recommended, followed by a spray of a nicotine solution
