those of Anomnglosms but even longer, the ligula more exsert but 

 normally foriued. The mentum tooth does not differ from that of 

 many othei-s, being rather broad at base and slightly impressed at tip. 

 The palpi do not differ from pensylvankus and its allies. The entire 

 oral apparatus seems to be more elongated, but beyond this no generic 

 character is presented. The elytral sculpture is also entirely unlike 

 any of our others. The punctures are distributed nearer the sides of 

 the intervals, and a feeble attempt appears in the inner intervals at a 

 biseriate arrangement. 



I have before me two females collected by Messrs, Hubbard and 

 Schwartz, at Lake Harney and Haulover, Florida. The males might 

 give another generic determination. 



10. C. circunicinotus. Say. — Body beneath black, above green, elytra 

 darker, legs rufo-testaceous. Head minutely punctulate, labrum truncate, 

 palpi slender, autennpe brownish, three basal joints pale. Thorax broader than 

 long, margin narrowly rufous, sides arcuate in front, feebly sinuate posteriorly, 

 hind angles acute, not prominent, surface coarsely but sparsely punctured at 

 the sides, base, along the median line and in continuation of the basal impres- 

 sions, intervening spaces smooth and more convex. Elytra feebly shining, 

 basal line feebly subangulate at humeri, margin narrowly rufous, epipleurse 

 pale; surface with finely punctured strise, intervals flat, finely and not denselj' 

 punctulate and with rufous pubescence. Prosternum punctured in front, mar- 

 gined at tip, episterna sparsely obsoletely punctate. Metasternal episterna 

 long, margined, sparsely punctate. Abdomen punctured as in niger, bor- 

 dered with rufous at the tip and sides posteriorly. Length .40 — .44 inch ,• 

 10—11 mm. 



This species in its thoracic sculpture is the final and most feeble 

 imitation of that of niger^ and may be considered the link from that 

 species to those which follow. 



Although 1 am an advocate of the right of priority in nomencla- 

 ture, the fact has always been patent to me that there are certain 

 cases in which it should not be admitted. The present instance is 

 one of these. Dejean first described this species (fide Chaudoir), 

 under the name perplexus, from a discolored specimen which he 

 indicated from Senegal. I hold in such cases that where everything 

 is calculated to mislead, the description should be dropped as invalid 

 and the earliest proper diagnosis accepted. I therefore adopt Say's 

 name, although probably a year younger 



Occurs in the Gulf States and Cuba. 



11. C. texaniis, n. sp. — Body beneath black, legs pale, above bluish green, 

 elytra darker. Head very minutrly punctulate, an obsolete vertical puncture, 

 labrum truncate, antennae brownish, three basal joints pale. Thorax wider than 

 long, narrower in front, apex very feebly emarginate, sides arcuate and slightly
