528 SEVENTH REPORT OF THE FOREST, FISH AND GAME COMMISSION. 



Prof. Robinson as follows: "Palpi reddish-brown, short, the third joint extending 

 beyond the head. Head and thorax reddish-brown above. 



"Anterior wings reddish-brown, much clouded with fuscous beyond the middle. 

 A dark brown patch on the.costa and a smaller one on the disk below it indicate 

 the central fascia. 



" A large dark-brown sub-apical patch is continued as a broad fuscous shade to 

 internal angle. Fringes pale. 



"Posterior wings very dark fuscous above; pale testaceous beneath, tinged with 

 fuscous internally. Fringes pale testaceous. Abdomen fuscous above, pale testa- 

 ceous beneath. 



" Under surface of anterior wings entirely clouded with fuscous, giving in some 

 lights a purple reflection. Expanse, male, 20 mil., female, 23 mil." 



Parasites. Several small parasites have been reared from this insect. Messrs. 

 Riley and Howard record the breeding of a species of Mctcortis from specimens 

 on oak received from St. Louis, Mo., October 24, 1873. Microccntrus ddicatus 

 Cress, was reared from other specimens on oak from St. Louis, July 7 to 17, 1873, 

 and M. solidaginis Cress., MS. was obtained July 6, 1873, from specimens taken 

 on oak at St. Louis, Mo. The writer also bred parasites July 15th and 26th 

 from this insect and the young of a plant bug, probably Podisus placidiis Uhl. was 

 taken in association with this species and presumably preys upon it. 



Serica trociformis Burm. 



A small brown beetle a trifle less than ^ of an inch in length, may be met with 

 in considerable numbers on scrub oaks in June. It may be recognized by its black 

 head, very dark thorax and brick red, rather deeply grooved wing covers and by its 

 stout, somewhat rotund shape, plate 16, figures 13, 14. The beetles fly about from 

 bush to bush and eat small irregular holes in the foliage. A large robber fly was 

 observed by the writer preying upon this species. 



INSECTS OCCURRING ON TWIGS. 



Oak twigs afford sustenance to many species, and only a very few of those 

 coming under personal observation in recent years can be noticed at this time. 

 The following species of leaf hoppers represent some of the grotesque forms among 

 insects.
