Legs pale or bicolored. 2. 



Legs entirely black; head and thorax black, elytra dull bine. nigripes. 

 2. — Thorax entirely yellow. 3. 



Thorax black; elytra dull blue or green. luperina. 



3. — Elytra bicolored, maculate, vittate or margined. 4. 



Elytra uniform blue or green. viripidennis. 



4. — Head black, front pale.

 Elytra yellow with a small oval piceous spot at base, a larger spot 

 posteriorly. decor ata. 



Head entirely yellow. 



Elytra marked as in decoratct. sororia. 



Elytra piceous, suture and sides yellow. 4. 



5. — Elytra with elevated costas and punctate. coslipennis. 



Elytra not costate. 



Thorax with a moderately deep fovea each side. discoidea. 



Thorax transversely impressed. limbata. 



The place occupied by sororia is that formerly held by 

 decorata. It seems that the former table must have been 

 prepared with a specimen of sororia before me, which in 

 some manner disappeared and remained unthought of un- 

 til a specimen was recently given me by Mr. Schwarz. 



Phyllobrotica sororia n. sp. 



Elongate, parallel, similar to decorata. Head entirely 

 yellow, smooth. Antennae black, the under side of first 

 three joints pale. Thorax broader than long, entirely 

 yellow, smooth. Elytra sparsely punctate near base, 

 smooth near apex, yellow, a smaller oval piceous spot at 

 base, a much larger one posteriorly. Body beneath yel- 

 low; femora and base of tibiae yellow, tibiae and tarsi 

 black. Length .28 inch.; 7 mm. 



One female. Burnett Co., Texas. 



Closely resembles decorata, but easily known by the 

 entirely yellow head. In decorata the legs are entirely 

 pale as well as the three basal joints of the antennas, 

 while the outer points are never black.
