 backed cassid was taken on a weed at Hogtown Creek, April 9. Several 

 specimens were taken on oak foliage, December 2-3. 



This is more of a northern insect, and this record extends the dis- 

 tribution of the species for a considerable distance south of its usual 

 range. 



Chirida (Coptocycla) guttata Oliv. This species occurs on wild 

 sweet-potato vines and has been taken on wild mustard foliage. April 

 20-August 12.

Nyctobates barbata Koch. Found beneath loose bark of decaying 

 tree trunks. It is typical of this habitat. October 20. 



Epitragus tomentosus Lee. This is a very common species and is 

 found especially on oak the year round. According to Prof. Watson 

 this beetle is similar to the lady-birds in habits, feeding on various 

 scales.

 on the forest floor in both piney woods and hammock margin. January
