Length to end of abdomen 20-22 millims ; width of 

 base of pronotum 8-9 millims; expanse of wing covers 

 59 millims. 



Two males from Southern Florida are the only speci- 

 mens known to me at present. This is much narrower 

 than either of the other species of the pattern of C. hi- 

 costa Walker, to which it belongs. The structure of the 

 metanotal segment, forming as it does a scale-like plate 

 placed in the depression between the drum-covers, for-

 link of connection between the two genera. 

 2. C. reperta. New sp. 



Closely related to C. sordida, but broader, with clean 

 markings on the head and thorax, the inner ends of the 

 opercula overlapping and marked with black across their 

 base, and with the lateral margin of the pronotum more 

 expanded anteriorly. Head, as seen from above, blunt 

 and short, with the eyes prominent and directed obliquely, 

 top of vertex with a large bilobate, black spot which is 

 connected each side with a streak which runs along the 

 margin to the eyes, vertex crossed by a broad black 

 band which joins a semicircle of the same color next the 

 eyes, and also connects on the middle with a double 

 black spot behind the ocelli, the intervening surface is 

 tawny yellow ; face clouded with piceous each side, 

 pubescent, the front abruptly tumid, bordered with 

 piceous each side on the thickened margin of the longi- 

 tudinal sulcus, the transverse ridges fulvous, with the 

 intervening grooves more or less piceous; rostrum 

 reaching to the posterior coxae, the tip piceous ; and the 

 two basal joints of antennae yellowish, with the tip of 

 the second black. Pronotum fulvous, with a slender 

 anterior border, a median abbreviated line, and the broad 

 posterior and lateral margins greenish yellow, luteous 

 when old, the lateral margin strongly upturned, with the 

 anterior angle prominent, but curved, behind this the
