14 The Ottawa Naturalist. [Apr 



the capture of two specimens o{ Ar^ynms Triclaris and one of 

 Thecla Augustus, and in the woods near the railway station a 

 pair of Phyciodes Batesii were captured. 



Hemiptera. — But few specimens were collected in this 

 order, but mention may be made of the rathei unusual abun- 

 dance of CoriinelcBna nitiduloides and Pentatovia juniperina. 

 The former occurred upon Turtle-head and Goldenrod, and the 

 the latter swarmed upon the White Cedars at the Experimental 

 Farm. At a recent meeting of the Club an account was given 

 of the San Jose scale, and specimens of this insect were exhibited- 

 As was then stated, this minute insect, which has such enormous 

 powers of injuring fruit trees, has occurred at five jioints in 

 Western Ontario and at three in British Columbia. Vigorous 

 efforts are being made by the Provincial and Federal Govern- 

 ments to stamp out this pest. 



HymenoptEixA. — An unusually wet spring was apparent- 

 ly the cause of a noticeable scarcity of at least the larger forms of 

 hymcnoptera. This scarcity was particularly marked among 

 the social bees and wasps, whose colonies are started by solitary 

 hibernated fertilized females, styled queens. If unfavorable 

 weather prevents the mother bee or wasp froin obtaining food 

 Cor the first brood, it must follow that the growth of the colony 

 is greatly retarded, or that it may even perish, Micro-hymeno- 

 ptera seemed abundant on the comparatively few collecting 

 outings, but these minute forms are so numerous, and so varied 

 in their habits, that they may be obtained under almost any condi- 

 tions. A very nice series, including several additions to our 

 lists, was taken even as late as 3rd Oct., on the occasion of the 

 Club Excursion to Chelsea. The Ottawa representatives of the 

 genus Ichneumon have been recently re-studied and rearranged 

 and are found to number over seventy species, which may serve 

 to indicate the immense number of forms belonging to the order 

 Hymenoptera.
