176 ENTOMOLOGICAL NEWS. [June, 



and thoracic shield of a smaller specimen were of a dark brownish 

 black color. 



One larva pupated in a thin white silken cocoon attached to 

 one of the petals; this is probably the normal place of pupation. 

 Other larvae pupated on the glass sides of the cage, or on the 

 muslin cover. All had pupated by June 10. 



When first formed the pupae are of a light green color. They 

 gradually change to a dark brown color, lighter on the venter. 

 Length, 14 mm. Two transverse rows of minute spines project 

 caudad on the dorsum of each abdominal segment. The body 

 is sparsely clothed with long white hairs arranged similar to those 

 on the larvae. The pupa firmly attaches itself to the cocoon by 

 eight strong hooklets, two arising from each side of the long 

 narrow cremaster and four from its end. The pupal stage lasts 

 from ten to fifteen days. 



Most of the moths had appeared by June 22; none emerged 

 after June 25. Probably eggs are soon laid, and the young larvae 

 work on the leaves, perhaps becoming half grown by Fall, when 

 they go into hibernation in inconspicuous hibernacula on the 

 branches near the blossom buds. But, possibly the moths hiber- 

 nate and lay their eggs on the blossom buds in the Spring ; or, 

 perhaps the insect passes the Winter in the egg. 



Hundreds of Magnolia blossoms were destroyed by this Tor- 

 tricicl in 1891. No observations have since been made on its 

 habits and life-history. Upon receipt of my bred specimens of 

 the moths, Dr. Fernald wrote that he had then had the insect in 

 his collection for nearly fifteen years.

On Cicindela formosa and C. venusta, with remarks on 

 some sexual characters of the genus. 



By H. C. FALL. 



Among a small lot of Coleoptera recently received from Mr. 

 W. Knaus, of McPherson, Kans., were several examples each 

 of the two beautiful tiger beetles Cicindela formosa and its so- 

 called variety venusta. On placing the fresh specimens in my 

 cabinet and surveying the two series, the difference in facies 

 struck me as being something unusual, even in this genus of 

 variable species. A subsequent somewhat careful investigation
