It eats young cotton-worms and other insects in Mississippi. 



Sinea undulata Uhl. 



Sinea undulata Uhlkr, Proc. Calif. Acad. Sc, IV, 1894, p. 282 ; Leth. & 



Severin, Cat. Plemip., Ill, 1896, p. 199. 



Brownish-cinereous, pale gray, pubescent, similar to -S'. diadema, but wider, with 

 a shorter neck and femora, with the spines more numerous and crowded together on 

 the front division of the head, with the carinate lines of the middle of the pronotum 

 prominently and sharply defined, and the knobs each side of the base elevated, and 

 surmounted by a little tubercle ; three double series of spine-like black tubercles on 

 the anterior lobe of the pronotum. Venter with a series of oblique, white spots on 

 each side near the border ; scallops of the lateral border more prominent and placed 

 farther back than in S. diadema, the inner margin of corium white. Length to tip of 

 venter 14-15 mm. Width of pronotum, 3 mm. 



Habitat: California. 



This species, which will probably prove to be a variety or aberra- 

 tion of diadema, is quite a characteristic appearing insect. The type 

 has been seen and it seems to agree perfectly with the description. 

 None of the many specimens of Sinea examined by me were referable 

 to this species. The author's description is given above. 



Sinea confusa, sp. nov,

Sinea undulata Champion, Biol. Cent. Amer. Rhync, II, 1899, p. 292. 



Length 10-13 ™™' Prothoracic lobes as in diadema. Abdomen of the female 

 generally inconspicuously undulate, sometimes more pronounced but never as promi- 

 nent as in the typical diadema. The undulations usually rounded. Abdomen of 

 the male entire, or very slightly undulate. 



Habitat: Arizona. Type, no. 5364. U. S. Nat. Mus. 



This species has hitherto been confounded with diadema. The 

 two species do approach each other very closely but the extremes are 

 conspicuously distinct. Confusa has been also confounded with un- 

 dulata, but it is difficult to see how that could occur. The author's 

 discription of undulata, it seems, would preclude such a possibility. 



Of this species I have seen specimens from California, Arizona 

 and Texas in the United States and from various localities in Mexico 

 and Central America. Its habitat will aid to an extent in separating 

 it from diadema. Specimens sent from Mexico by Mr. Champion 

 have the abdomens of the females very slightly undulate, while those 

 of the males are practically entire.
