340 Annual Report for 1888 of the Consulting Entomologist t 
perature not being sufficiently liigb, keeping down the heat of 
the cargoes would be a means of pi'evention. 
I would therefore submit, for consideration of those con- 
cerned, whether, as it is an acknowledged fact, both practically 
and scientifically, that heat causes rapid increase of these pests, 
pending arrangements to prevent shipment of foul cargoes, the 
temperature of the bulk might be lowered by the plan sometimes 
followed with large masses of grain on shore, of having what are 
called " air-drains " through the mass, thus preventing the great 
heating. 
I should also add that, as I am aware that this subject in- 
volves most important interests, I have not ventured to bring it 
forward in the one branch in whch it falls in my own depart- 
ment, until after communication with leading firms, from whom 
(as T have noted) I have received information that the import 
of foul grain is a cause of so much trouble and unnecessary 
expense to millers, that by protective associations, and formal 
appeal — with more or less success as the case may be — they are 
endeavouring to protect themselves from continuance of the 
injury ; and I must acknowledge the courtesy with which my 
requests for information have been met when the object of the 
inquiry was known. 
Otlter Insect AttacJcs on Farm Crops. 
In the course of the year inquiries have been sent regarding 
almost every one of our common farm crop attacks, and also re- 
garding a few which have been little, or not at all, recorded 
previously as crop pests in this country. Also as to getting rid 
of ant-hills in pastures ; and regarding bean weevils ; beet-carrion 
beetle (new as a crop pest in England) ; black currant gall mite 
(a serious pest to growers) ; cabbage and turnip gall weevil ; 
cabbage root maggots ; carrot root fly (producing " rust ") ; 
cockchafers, and small chafer maggots in peat moss litter (which 
I reared to maturity, and found to be Aphodius fmetarivs, and 
consequently harmless) ; chlorops on barley ; clover sickness 
produced by eelworms ; corn aphis, and corn saw-fly. Daddy 
Longlegs attack was little rejDorted, and not much inquiry made 
about turnip flea beetles. 
Other attacks reported have been Hessian fly to a small amount, 
and communication regarding its parasites ; also hop aphis, horse 
warble, and bad and widespread attack of the wheat-bulb maggot 
of the small two-winged fly, the Hylemia coardata. Likewise 
millepedes attack to mangolds, besides that of beet carrion 
beetle previously mentioned, and mustard beetles. Otiorhynchus 
weevilsj of which several kinds are very destructive in bush fruit
