vivid violet green, margined with reddish, while those of the Eiery Hunter, 

 Calosoma calidum, are black, marked with regular rows of yellowish, punctated 

 dots. 



These species destroy a large number of destructive, leaf-eating insects, tent- 

 caterpillars, cutworms, canker-worms and other equally injurious forms. Their 

 segmented, flattened larvae burrow just beneath the surface of the ground and 

 attack the insects entering the ground to complete their development. These 

 larvae are very active and so well-armed with a sharp pair of jaws, that they are 

 able to overcome larvae much larger than themselves. The adult insects hunt at 

 night, and like the larvae feed upon other insects. Because of this nocturnal 

 habit and their hiding under stones and logs during the day, they are seen less 

 frequently than some other insects that are not so plentiful. They are, however, 

 found often in the mornings on the pavements under the electric lights that have 

 attracted them during their night-marauding expeditions. 



There have been very few acorns on the mossy-cup oaks, Quercus macrocarpa, 

 in this locality for several years, but this season, on the contrary, nearly all the trees 

 are well-fruited. A large number of the acorns bear on their cups galls produced 

 by Andricus glandulus. These galls resemble closely minature acorns, as the 

 inner gall containing the larvee is formed in a small cup with a mossy-fringed 

 border like that of the acorn. When mature the inner gall falls out of the cup to 

 the ground, where the larva remains in it and does not mature until the following 

 spring.

One of the first events of the season was the appearance of borers about 

 Virginia Creeper on a neighbour's garden wall. Warned by the previous year's 

 date of emergency I was on the look out before the close of May. Sure enough, 

 on the 29th of May I began to find specimens of Psenocerus supernotatus about the 

 broken stems and dead twigs at the base of the shrubbery and in the course of four 

 or five days captured over a score of these. On May 31st I observed the first 

 specimen of Saperda puncticollis, and between June 1st and June lOah I captured 

 over forty. They were nearly always taken on- the foliage near the top of the 

 hedge. In bright, hot sunshine they became very active crawling out on to leaves 

 and flying about with great readiness. On June 19th while exploring a wood 

 west of Bethany Junction I found feeding on the blossoms of maple-leaved 

 Vibernum or Dockmackie a species of Leptura that was new to me; it proved to 

 be L. octonotata. On June 30th while exploring the northwest corner of the 

 famous Murray Swamp between Meyersburg and Codrington, on the alders at its 

 edge I captured my first specimen of the handsome little buprestid Eupristocerus 

 cogitans. 



On Saturday, July 17. while wheeling across the Oak Hills between Stirling 

 and Frankford, noticing large patches of New Jersey Tea in bloom about the 

 edges of the groves of oak and p_ine, I dismounted in the hope that the oak might 

 breed certain new species of anthophilous beetles ; my hopes were realized by finding 

 among several familiar forms of Leptura and Typocerus, the less common 

 Typocerus luguhris and Leptura zebra; the latter I regard as quite a prize; it 

 bores in oak and I made three captures in my short stay. 



On Tuesday, July 20th, while on a botany trip north of Norwood, I spied a 

 specimen of the brilliant little Chrysobothris Harrisii settling on some pine brush ; 

 I had only once before seen this creature (many years ago, at Lanark) and had
