Protoparce (Herse) cingulata. (6) Ichneumonidae : Ichne^imon koebelei^ 

 Sw., ■psbTasitising Cirphisunipiincta, Haw. [siTmy-woTm.), Agrotis ypsiloriy 

 Rott., (black cutworm) and related larvae; the rate of reproduction 

 of this form is slow ; Echthromorphafuscator, ¥., reared from Vanessa 

 tammeamea, l^sch., Lycaena boetica, L., Phytometra cJialcites, Esp., etc. ;. 

 Pinipla hawaiiensis. Cam., parasitising the same species as the Echthro- 

 morpha ; Henicospilus s^^.,ixon\Agrotis s-p.,Scotorytha sp. and Pyralids ; 

 Cremastus hymeniae, Vier., from Hymenia recurvaMs, F., Plilyctaenia 

 spp., Bactra straminea, etc. ; Limnermm polynesiale, Cam., 

 from Plutella maculipennis, Curt, (diamond-back cabbage-moth) ;, 

 Limnerinm hlackhurni, Cam., from Nacoleia asaphotnbra, Meyr., Tortrix 

 {Archips) capiwina, Wlsm., Tortrix spp., etc. (7) Braconidae : 

 Chelonus hlackburni. Cam., from Hymenia recurvalis, F., Gelechia 

 gossypiella, Phlyctaemia despecta, etc. ; the larva lives singly in the 

 host larva, emerging after the latter has made its cocoon ; Apanteles 

 sp., reared only from Opogona aurisquamosa, Butl., but probably 

 attacking other Microlepidoptera whose larvae feed in decaying 

 vegetation on the ground ; Bracon omniodivorum, Terry, introduced 

 to parasitise the palm and sugar-cane leaf-rollers ; 75 per cent, of the 

 larvae of the Nacoleia accepta have been found to be parasitised by 

 this Braconid ; the eggs are laid on the outside of the larva, hatch 

 in one or two days, and the larvae reach maturity in from 3-4 days ; 

 the complete life-cycle occupies about 14 days ; Hahrohracon hebetor, 

 Say, reared in large numbers from Plodia interpunctella and Epihestia 

 elutella ; the short life-cycle of about two weeks allows for such frequent 

 generations that this species is very effective in controlling flour moths.

Xylocopa aeneipennis, De Geer, and Lithurgus albqfinibriatus, Sich., 

 were found boring in blocks of Acacia koa, Gray, which had been 

 stored for some time. The chief damage was to the sap-wood, though 

 in several places the burrows extended to the heart-wood. The larger 

 tunnels were from 3 to 6 inches long and young of all stages were 

 found inside chambers connected with them.

 d'H§relle, on Locusts in the Philippines.^P/a/?jD^nwe Jl. Sci.,

In view of the reported successful use of Coccobacillus acridiorimi, 

 d'Herelle, in the destruction of locusts in Argentina, this method was 

 tested in the Philippines. The culture was received in May 1913 and 

 its virulence was increased by the inoculation of a series of locusts, sub- 

 sequent lots being inoculated with material taken from dead or dying 

 locusts of the preceding series. In the first series, carried to the 30th 

 set of insects, faeces were expressed from the abdomen and diluted 

 with broth as the directions recommended. It was soon found that 

 the insects did not show the required symptom, i.e., liquid excrement. 

 In the second series, bacilli were taken entirely from the body-cavity ;
