iV2 THE CANADIAN ENTOMOLOGIST. 



In the identification of this insect occurred an episode that I hope 

 Dr. Bethune will pardon me for introducing here. At the close of this 

 season of 1906 I purchased a copy of LeConte i\; Horn's key to the genera 

 of N. A. Coleoptera. I'-y a somewhat rough process of elimination I had 

 decided my beetle belonged somewhere in the tribe C/yti/ii, whose most 

 familiar representative is probably the famous sugar-maple borer, 

 Plagionotus speciosus. LeConk & I bun's book made it probable that in 

 the third group of this tribe, the Amiglypti, it would find its place. This 

 group contains four genera, Microclytus, Cyrtopkorus, Tillomorpha and 

 Euderces. Only one of these genera was at all known to me, and that 

 from a single species ( Euderces picipes) somewhat resembling the subject 

 of my examination. 1 found first of all that the beetle I was trying to 

 place had no ivory marks on the elytra, which put Euderces out of the 

 question ; the eyes were oblique and emarginate instead of round, which 

 excluded Tillomorplia; it must be either Microclytus or Cyrtopkorus, and 

 the book gave one no choice, for in Microclytus the second joint of the 

 antenna was equal to the fourth, while in Cyrtopkorus the second joint 

 was much shorter, as it obviously was in my specimens. My fellow- 

 collector had already sent a box of unidentified specimens to Guelph to 

 be named, and when they came back I was naturally eager to learn the 

 result. To my chagrin I found my little favourite christened Microclytus 

 gazellula. This so mystified me that at last I wrote to Dr. Bethune, 

 explaining the quandary I was in. To my great relief I got an immediate 

 reply, that the beetle sent him had been identified from a cabinet speci- 

 men named by an older collector. LeConte & Horn were right, my beetle 

 was Cyrtopkorus verrucosus, as were those in the Guelph cabinet, though 

 hitherto wrongly named. 



I have examined a number of cabinets, and in none of them yet have 

 I found more than an odd specimen of this beetle, nor have I met a 

 Coleopterist who had captured it, except accidentally, as it were. But on 

 the blossoms of the early elder, still more those of hawthorn, sometimes of 

 choke-cherry, dogwood, spiked maple, viburnum and New Jersey tea, from 

 the middle of May till early in July. I have found it abundant. It is then 

 replaced by its near relation, Euderces picipes, which frequents blossoms 

 all Jul}-, especially those of New Jersey tea and milkweed, though often 

 met with also on certain of the rosacea; and composites. It closely re- 

 sembles Cyrtopkorus, though considerably smaller and not so elegant in 

 form : on the side of each elytron is a transverse white band, technically 

 termed an ivory vitta ; in the first specimens captured I did not recognize 

 a new kind till I took them out of the killing-bottle.
