elytra regularly striate punctate, with the 3d and 8-9tli inter-

2. Second interstice brown, exterior vittfe irregular, disrupta. 



b. Thorax brown, anterior angles broadly ochreous, interstices punc- 

 tate. 



1. First vittsD free, not joined to the suture. exclamationis. 



2. First vittfB confused with the sutural line. 



Two lateral vittae joined a little before the apex, no extra 



marks. continua. 



Lateral vittse joined at , traces of the external vittae visible. 



conjuncta. 

 9 C. exclamationis, Fabr., Rogers, 1. c. 



10. C. conjuncta, Rogers, 1. c. 



With this is to be united G. stolata, Suffr. from Mexico, and C. 

 pallida, Bland ; both differing in the more or less iuterrupted vitt?e. 



11. C. continna, Lee, Tr. Ent. Sec. 1868, p. 57. 



Very near C. conjuncta, but with two lateral rather broad brown 

 vittse and no traces of the external one. The coloring is that of 

 C. suturalis, from which the punctate interstices distinguish it. 



12. C. snturalis, F.ibr. (1775), Stiil, 1. c. 



This name is to be preferred to pulchra, under which he de- 

 scribed it in 1792; C. casta, Rogers, is merely a variety in which 

 the lateral vitta is divided into two. 



13. C. disrupta, Rogers, 1. c. 



In this the lateral vittae are obsolete; a smaller A'ariet}' occurs 

 in Texas and Colorado with slightly different markings. 



D. CALLIGRAPHA, Er. 



a. Elytra more or less distinctly striate punctate, resembling Zygogramma. 



1. Thorax brown. 



* Sutural vitta uniform. similiit. 



** Sutural vitta dilated before the apex. iiicisa. 



2. Tliorax willi sides, and from margin yellow. pracclm. 



3. Thorax yellow with black marks, form narrow. elegans. 



b. Elytra striate punctate, thorax brown, last joint of palpi very large. 



lunata.
