being desired in the larval state for comparisons both in the home and 

 other collections. Investigations of the plant disclosed a fearful state of 

 insect depredation, quite enough to discourage any attempt at rearing the 

 Hop here on a large scale. The root was our objective point for iminanis^ 

 as by this date the young larvae should have left the extremities of the 

 vine and sought the more bulky root-stock for an abode. No larvae are to 

 be found, however, and attention turns to the other insect foes which are 

 so sadly in evidence. Broods of coleopterous larvje, accompanied by 

 their parents presumably, have the foliage half riddled, and later this work 

 is complete. They were assisted by four different species of lepidopterous 

 larvse, and a tiny Micro soon takes up an abode at the blossoming end, 

 feeding upon forming seed-vesicles. A long cylindrical gall on a main 

 stalk, upon being opened, discloses a nest of wriggling, yellow maggots, 

 the young of the true gall-fly doubtless, since the growth seems to have 

 been so recently formed. Surely the local Hop has enough to contend 

 against without immanis at hand to gnaw them off at the root, since this 

 is one of its tricks, as chronicled by the economic writers, and there would 

 be no chance for the vines at all if the latter occurred here plentifully. 

 Not recalling that the Hop was listed as being given to any gall-maker, 

 causes some attention to centre here. A number of the galls prove more 

 tapering and of larger diameter than the one first opened, and one is seen to 

 have the end gnawed out in a peculiarly suspicious manner. A half- 

 hearted search discloses a well-developed Gortynid larva, much discomfited 

 at such reckless trespassing. And so this must be immanis, not working 

 at the vine's ti)) nor down by the root as wc have been informed, but 

 midway in a tidy gall, one which in no way interferes with the plant's 

 growth. Later on these larvae are found to still cling to their comfortable 

 galls, matiuing there and jfrodiicing no visible harm in the growth of the 

 stalk. From which it would appear immanis has been a much-maligned 

 species at the hands cif the economic writers. But this conclusion was 

 hasty. 



Examples are secured for inflation, and a very few go on to pupa; in 

 the breeding cage. A short pupal stage is followed by an emergence, not 

 of the Guenee species, but the long-sought circumluccns of Smith. It so 

 happened that the plants examined locally were widely separated, yet in 

 every case there were numerous galls containing the circumluceiis larvse 

 upon eacli, and they are so evident and jilentiful that it becomes at once 

 a most easy species to apprehend. It is recalled how in exchanging for
