THE CANADIAN ENTOMOLOGIST. 16.1 



To illustrate the biting power of iliese small larvae, one which I 

 allowed to seize the point of a dissecting needle held itself suspended 

 therefrom, at an angle of about 45 degrees, for a period of nearly two 

 minutes. 



No attempt was made to rear these larvse, but on June 10, 1907, I 

 again visited the hedge and collected a suit-case full of the wood. 'I'his 

 was principally dead, but I made it a point not to get that which was too 

 old and brittle, as some of it which I examined on the ground did not 

 appear to contain any wood-boring larvye— nor did I find any in the living 

 wood which I secured. 



This material was brought home and examined, and it was found 

 that there were apparently several kinds of living larvse therein. It was, 

 therefore, cut up into suitable lengths and placed in air-tight glass jars, 

 or glass cylinders with cotton batting at top and bottom, and set away in 

 my laboratory. The first beetle bred from these dead branches appeared 

 June II, and proved to be Neoclytus erythrocephalus^ Fab. Other 

 specimens of this species emerged later. 



On June 20 a specimen of Clerus quadrigiittatus, Oliv., was found 

 alive in one of the jars, and several other specimens of this species 

 appeared later. It is probable that their larvae were feeding upon the 

 larvae of some of the wood-borers in the Gleditschia^ as most of the Clerid 

 larvae appear to be carnivorous. On June 24 three specimens of Lioptis 

 fascicidariSs Harr., all alive, were found in one of the jars ; also a speci- 

 men of MelanopJithalma disti?iguenda^ Com., and one of Liopiis varie- 

 gatus, Hald. Another specimen- of the latter species had emerged a few 

 days eailier, but escaped. 



A specimen of Tropideres rectus, Lee, emerged June 29 or 30. The 

 pupal cell of this specimen had been opened when the branches were cut 

 up. At this time it contained a larva. The pupa was observed several 

 days before the adult emerged, but the exact length of time of the pupa 

 stage was not determined. 



On July I a specimen of Ecynis dasycerus, Say, emerged, also one 

 of P/iyton paUidu77i, Say. Like Clerus quadriguttatus, this Clerid was 

 (as a larva) doubtless feeding upon the larvae of the wood-borers. 



No specimens of Agrilus fallax, the species which I most expected 

 to secure from the Gleditschia, emerged. However, when cutting up the 

 branches from the jars, a living Buprestid larva similar to if not identical 

 with the larvae found in 1906, was found, which I thought was probably a
