Cryptoceplmlus ornatus Fabr. Syst. Eleut. pt. 2, p. 47, no. 32, 

 Coqueb. Illustr. Icon. Insect, p. 129, pi. 29, fig. 10, a. b. 



Desc. Body reddish-brown : antennas black, five basal joints pale 

 reddish-yellow ; orbital line yellow : thorax with the anterior and 

 lateral margins yellow, the edge black ; base with two yellow, oblique 

 abbreviated lines, curvilinearly united over the scutel, so as to form 

 an arc of a circle : elytra pale yellow, with two black, abbreviated 

 vittae on each, and a black suture ; the lateral vitta originates on 

 the humerus, and terminates near the tip; the inner one is 

 oblique, and becomes confluent with the suture a little beyond 

 the middle; the common black sutural vitta includes the scutel 

 at base, and does not reach the tip; edge all round, black; anal 

 segment with an obscure yellow arc. 



Obs. The ornatus of Herbst, in Fuessly's Archives, and of 

 Olivier in the Encyc. Method, is quite a different insect from 

 the present ; but as that is an uncertain species, we prefer retain- 

 ing the name for our insect. 



This species is an inhabitant of various parts of the United 

 States. I have found it in the middle and southern States, at 

 the Rocky Mountains, and in the North-Western Territory. It 

 is subject to vary, in having the exterior vitta of the elytra so 

 widely interrupted in its continuity, as to exhibit only two re- 

 mote spots.

[Not the Fabrician species according to Suffrian (Linn. Ent. 6, 

 241) and named by him C. calidus. Much confusion exists 

 among our striped Cryptocephali, and examination is still neces- 

 sary to distinguish species from races and varieties. — Lec] 



Cryptocephalus conpluentus[confluens]. — Specific char- 

 acter. Rufous ; elytra yellow, trilineate with black ; the inner 

 line confluent with the suture beyond the middle.

Desc. Body yellowish-rufous : head impunctured, yellow ; a 

 rufous spot on the vertex, and another surrounding the base of 

 each antenna : antennae black, pale at base : thorax impunctured ; 

 anterior and lateral margins yellowish ; lateral submargin more 

 deeply rufous than the disk : scutel black : elytra pale yellow, 

 with punctured striae; three longitudinal, nearly parallel black
