A. maculiventris Say. (spinosus Dall). Common throughout the State 

 all season. 



A. serieventris Uhl. Recorded from all sections of the State VI-VIII, but 

 there is a question of determination involved, and most of the speci- 

 mens may prove "maculiventris." 



A. modestus Dall. Madison IX, common (Brb) ; Staten Island IV (Ds). 



A. placidus Uhl. Hewitt -VII, 25 (Jl) ; Madison VIII (Brb); Staten Island 

 VIII (Ds); Jamesburg (Coll); Lakehurst VII (div).

Family THYREOCORID/E. 



These are the CorimelgenidaB or "negro bugs" of the previous edition, 

 so named because of their generally uniform black color. They are 

 shining, convex, almost as broad as long, the scutel covering almost the 

 entire abdomen, and they resemble beetles of the Histeridse more than 

 they do the usual run of bugs. They lay their eggs in black and rasp- 

 berries, and these eggs have a peculiar bed-buggy flavor, which becomes 

 offensively apparent when the fruit is eaten. 



THYREOCORIS Schrank. (CORIMEL>ENA White.) 



T. unicolor Pal. Beauv. (atra A & S.) Throughout the State V-VIII, 

 sometimes locally common. 



T. nitiduloides Wolff. With the preceding, but more rare. The form that 

 occurs in New Jersey is said to be a variety, the typical form being 

 western. 



T. lateralis Fab. Hewitt VI, Newfoundland VII, Staten Island VII, James- 

 burg VII (Ds). Mr. Barber suggests that this is "gillettii" Van D. 



T. anthracina Uhl. Pennsylvania, and sure to occur in New Jersey. 



T. gillettii Van D. Staten Island V (Brb); Cape May C. H. VIII, 21 

 (Van D); Anglesea VII, 12 (Coll).
