20 THE EEPOET OF THE No. 36 



Besides these, seven or eight other species of Leptura were noted and ten 

 other genera of cerambycid. In the latter part of June, larvae, pupas, and imagines 

 of the very handsome Ladybird {Anatis 15-punctata) were found in great num- 

 bers on leaves of elder, ash, butternut, basswood and maple. About one-fifth of 

 these were of the normal form, the rest were of the variety mali, in which the 

 elytral spots are "eyed" with a narrow halo paler than the ground color. This 

 mention of varieties recalls a point of interest in connection with an insect taken 

 in 1914, but not identified by me till after our last meeting. The insect is the 

 Staphylinid Oxyporus, but as my report is a long one I will omit the note, as I 

 have done with similar notes on Hoplosia nubila and Pogonochcerus mixtus. 

 The note is mainly of systematic interest. 



At the end of June I went down to Port Hope a few days before reporting 

 for duty in Toronto. While there I visited a hardwood four miles north of the 

 town, where axe and saw had been busy in the winter. Again I will save space 

 by listing the more interesting captures made: 



Neoclytus erythrocephalus (dead twigs of hawthorn and 



maple) 3 



Arrhopalus fidminans (under bark, stump of butternut) .... 1 



*Calloides nohilis (under chip of oak) 1 



*Centrodera decolorata (maple stump) 1 



Elaphidion villosum (oak stump) 1 



^Pogonochcerus mixtus (pine trunk) 1 



*Goes oculatus (willow foliage) 1 



The last beetle in this list was captured on the old home farm of Mr. John 

 Hume. There is a swamp here just below a high ridge of land to the north, and 

 where the willows are thick two streams flow out from the swamp, one about the size 

 of a field drain, the other rather larger; the smaller flows south-east, the larger 

 south-west. In the w'illows here I noticed a number of wasps flying to the stems. 

 The stems proved to be covered with recent bore-holes, from which was exuding 

 dark pulp. It was evidently the pungent smell of fermenting sap that had brought 

 the wasps, and while I was investigating, several butterflies hovered or settled 

 about the bores and two beetles (Gaurotes cyanipennis) were taken feeding at 

 them. Presently I discovered a pair of weevils, with a large white patch near 

 the apex of the elytra, resting on a stem a foot or two above the bores. It was 

 Cryptorhyncus lapathi ('as I have since learned from Mr. Caesar).* I was unable 

 to see any insect emerge from the tunnels, nor did I notice any ovipositing. 

 Soon after. Dr. Watson came out with me and we captured over 20 of these 

 curculios. Next day I had to go to Toronto as an associate examiner. This 

 was about the 3rd of July. Dr. Watson visited the place about four times in 

 the next five weeks and never failed to find several of these creatures on the 

 willow. At Thanksgiving I visited the same place and also followed the larger 

 stream for half a mile south-west. No insects were to be found .on the trees, and 

 though I took some infested stems home with me, I could find no trace of eggs. 

 There were several larvae, but I could not identify them for eertain. One looked 

 like the larva of Saperda concolor. The willow worst-bored appeared to be Salix 

 discolor. Trees of Salix nigra seemed immune and also those of a species I could 

 not identify — the leaves broad and not very long, rugose with veins on the upper 

 side and downy beneath. The foliage was partly shrivelled in October and there 

 seems to be much intergrading among the willows, which makes identification un-
