CREAGROPHORUS.—CYRTUSA. 85 
all these hooks being more or less rudimentary in the female ; tibise moderate, scarcely incurved, spinose 
on the outside, and furnished with a short spur on the inner side of the apex; tarsi short, robust, and 
compressed. Underparts rufo-testaceous. 
Hab. Panama, Volcan de Chiriqui (Champion). 
This species differs from the preceding in its smaller size, more ovate and less convex 
form of its body, uneven surface of the head and thorax, almost impunctate elytra, and 
doubly-hooked posterior femora. ‘The last-mentioned character is nevertheless variable, 
and in some examples, especially those which I suppose to be females, evanescent; but 
in all the four specimens now before me this armature is more or less apparent. 
CYRTUSA. 
Cyrtusa, Erichson, Naturg. Ins. Deutschl. iii. p. 77 (1845). 
Body more or less hemispheric, not contractile. Head rather large, with antennal grooves beneath. Thorax 
transverse, widest at the base. lytra large, entire. Antenne generally short, 11-jointed, 8 often 
very minute, 7-11 forming a rather abruptly incrassated club. Prosternum small, produced and dilated 
behind the coxal cavities; episterna small; epimera rather large, partly enclosing the coxal cavities ; 
coxal cavities large, enclosed behind. Mesosternwm rather large, deeply excised in front; episterna long 
and narrow, humeral; epimera long and very narrow, reaching to the coxal cavities ; coxal cavities long 
and large, not contingent. Metasternum short, not extending to the sides of the body, slightly produced 
between the cox ; episterna rather small, not reaching the coxe ; epimera long and narrow, extending to 
the coxw. Venter composed of six segments, 1-5 nearly equal, 6 very small. Legs generally short and 
robust ; intermediate and posterior tibize spinose, often much dilated; posterior femora often incrassated 
and truncate at the apex; tarsi 5-, 5-, 4-jointed. 
Eight species of this genus have been described, all from Europe or North America. 
One species, apparently identical with the North-American C. dlandissima, inhabits 
Guatemala.
