June i6 to 19. — 9 laid 151 smooth, glossy, pale greenish yel- 

 low eggs, somewhat flattened, 2 mm. greatest diameter. 



June 23. — Some of the eggs changed to dirty white, and the 

 young larvae could be seen within. 



June 24. — Eggs commenced to hatch; young larva pale green- 

 ish white, 6 to 7 mm. in length; head and thoracic segments 

 large; caudal horn 1.5 mm. in length, reddish brown, darker at 

 base and tip; two spines at tip, making it appear pronged; horn 

 usually straight, or nearly so, but in some cases much curved; in 

 this moult it points backward. 



July 28. — Larva full grown; length 38 mm.; green, with yellow 

 granulations; seven yellow, oblique; lateral stripes, the last reach- 

 ing base of caudal horn; an indistinct, yellow, longitudinal, lateral 

 line to fifth segment, and continued faintly; a variable number of 

 red dorsal spots or blotches, two on a segment; some have but 

 two small red spots on the third segment, and on others red is 

 the predominating color of the dorsal region; caudal horn straight, 

 pale green ; two thorns at tip ; points foru-ard ; several days before 

 pupating the green of the dorsal region fades to a dull yellow. 



August II. — First larva pupated; although provided with a 

 plentiful supply of light, moist earth, none of the larvae attempted 

 to enter the ground, but pupated upon the bare soil. If this is 

 their habit in nature, it may in part account for the rarity of this 

 insect, but I have noticed the same thing with other and com- 

 moner species when confined in breeding-cages, and its rarity is 

 probably due to some other cause. 



Notes on a few Virginian Dragonflies. 



BY PHILIP P. CALVERT. 



Some months ago Mr. Wm. D. Richardson, of Fredericks- 

 .burg, Va., sent to me, for identification, a few dragonflies which 

 he had taken in Spottsylvania County in that State. These speci- 

 mens may interest some readers as adding new data for geo- 

 graphical distribution. Excepting ^. heros, none of these spe- 

 cies have been recorded from Virginia before, although P. 

 trimaculata was known to inhabit the United States everywhere 

 east of the Rocky Mountains. The notes which Mr. Richardson 

 sent with the specimens are enclosed in quotation marks.
