114 Dr. A. S. Packard, Jr' Revision of the 



smooth, yellow; mesial furrow of propodeum well marked, traversed 

 by minute rugae; enclosure sublunate, nearly obsolete, with numer- 

 ous fine diverging longitudinal stria?, and on the posterior part similar 

 fine transverse raised lines. Tegula? and basal hinge pieces of wings 

 rufo-testaceous, concolorous with the nervures and pterostigrua, wings 

 slightly clouded on the outer half, where the nervures become darker 

 than on the basal half. 



Legs : coxa? and femora rufo-testaceous, the latter yellowish at tips ; 

 tibiae yellowish, beneath rufous, spinulated, though not very stoutly 

 so ; tarsi dull fusco-testaceous, unguinal joint dark brown. 



Abdomen considerably shorter than the head and thorax together, 

 rings coarctate, convex, sutures well defined, surface well punctured ; 

 the first ring as in C. croesus and C. stirpicola is separated from the 

 succeeding ones by its unusual convexity, and contracted at the 

 sutures, where it is slightly emarginate, black, second ring with a con- 

 tinuous yellow band unusually broad, but contracted in the middle. 

 Third ring with a narrow linear continuous yellow band interrupted 

 uear the side where is a supplementary linear spot ; the succeeding 

 fascia? of same length but broader, not interrupted, but with a deep 

 angular sinus. 



On the upper portiou of the fifth ring is a broad, short fascia. 

 Tip black, mucronate, deeply channelled, much narrower than in 

 C croesus. 



Length of body, .48; head and thorax, together, .28; abdomen. .20 

 inch.

This agrees precisely with St. Fargeau's description, and in its most 

 important characters is allied to G. croesus; the two agree in the co- 

 arctate basal ring of the abdomen, also in the slightly contracted pro- 

 podeum which is more separate in this group of the genus than usual. 



Likewise both species have a continuous fascia on the second and fifth 

 rings, while in C. croesus the lateral rounded ovate fascia represent 

 the linear bands in C. scaber, and the meso-scutum is yellow in the 

 former species, while in C. scaber it is entirely black, though this is 

 usually a character of slight importance. 



Differs in the fuscous legs and coxa?, which last are as a rule in the 

 other species always black, and which is probably owing to its tropical 

 habitat, as most of the species from the south arc uniformly more 

 broadly spotted with yellow; and the pubescence of the head being 

 golden rather than silvery in its hue. The species will also be
