In discussing Mr. Dwiglit Pierce's paper on Diajjrepes [see this 

 Revieiv, Ser. A, iii, p. 627], the author states that D. esuriens should not 

 be treated as a synonym of D. famelicus, which was described from 

 Guadeloupe. A distinct race, D. jamelicus elegantulus, Gyl., occurs in 

 Martinique. The Barbados form is quite distinct from this and was 

 probably introduced from the northern islands. The variety figured 

 by Mr. Pierce as D. comma, Boh., is D. doiiblieri, Guer., the true 

 D. comma occurring in Venezuela and Trinidad ; that figured as 

 D. marginatus, Oliv. , is undoubtedly D. farinosus, Gyl. , and is possibly a 

 synonym of D. rolirii, F. The form described as D. denudatus, Pierce, 

 is the true D. marginatus, Oliv., from Guadeloupe. 



The following are among the new weevils described : — Diaprepes 

 balloui, sp. n., from Dominica, being the representative in this island of 

 D. hemigrammus, Chev., in Martinique ; D. famelicus barbadensis, 

 subsp. n. , from Barbados on Agave americana ; Pachneus citri, sp. n. , 

 found on citrus in Jamaica ; P. marmoratus, sp. n., from a yam plant 

 in Jamaica ; and Styracopus phaseoli, gen. et sp. n., from Dominica 

 and bred from larvae boring in the stems of Lima beans, St. Vincent.

Investigations on cotton bollworms has led to the discovery that 

 there are apparently at least five different species of Rhogas which 

 attack Earias fabia and E. insidana: During June and July, 158 

 larvae and pupae of Rhogas spp. were despatched from Pusa to Hansi, 

 and these parasites are now fully established in the experimental plots 

 there. Rice has suffered from the formation of galls in the stem, 

 caused by a small fly, Pachydiplosis oryzae, Wood-Mason, on which 

 further investigations and experiments are being made. The Jassids, 

 Nephotettix bipunctatus and N. apicalis, were serious pests in the Central 

 Provinces. Attempts to breed these species from eggs in captivity 

 have failed and the life-history from December to June is at present 

 unknown. The Fulgorids, Sogata jjusana, S. pallescens and S. distincta 

 have also occurred in the Central Provinces and the mealy-bug, Ripersia- 

 sac^hari niger, at Balasore. Sugar-cane borers apparently belong to 

 two or more species of Diatraea, which also occasionally attack juar and 

 maize ; the normal borer of the latter, ChiJo simplex, is rarely found in 

 sugar-cane. In the Central Provinces an effort is being made to check 

 boring pests, in this case principally Schoenobius, by varying the time 

 of planting sugar-cane. A memoir on Pyrilla aberrans is being prepared. 

 The sugar-cane Aleurodid, Aleurolobus barodensis, caused considerable 

 damage in Tharsa ; attempts to discover any important parasite of 

 this pest were unsuccessful. Papua depressella, which usually bores 

 the roots of cane, has now been found attacking young shoots of newly- 

 planted cane, causing greater damage than either Diatraea or Scirpo- 

 ■phaga. Lead arsenate proved the best preparation for protecting cane 

 setts against termites, but further experiments for the protection of the 

 new shoots in setts are being undertaken. On indigo, the indigo Aphid
