are distinctly sinuate inwardly, tri-dentate outwardly, the basal tooth, 

 however, being much smaller than the median one, and the inner 

 apical part of the fore-tibiae is more dilated ; this dilatation of the 

 tibige and also the deeply incised and sub-tuberculate clypeus are the 

 two characters distinguishing this species from G. hrachyjyterits, 

 in which the anterior tibiae have also a third, slightly angular 

 projection above the basal digit, but are not quite tri-dentate ; the 

 females, however, of these two species are hardly distinguishable, 

 except that the prothorax is more broadly flavescent laterally in 

 C. excisus. 



Length 3f-4j- mm. ; width 2 mm.

DEEPANOCANTHUS, n. gen. 



Buccal organs of Harmogaster ; clypeus very deeply emarginate, 

 diagonal laterally from the genae, which are angular, in a line with the 

 eye ; prothorax not obliquely attenuate laterally towards the base, 

 and w^ith a median longitudinal basal groove ; elytra sharply carinate, 

 with the intervals crenato-punctate ; the two basal segments of 

 abdomen carinate in the middle, and not free ; anterior tibiae of male 

 tri-dentate outwardly, truncate, and with the apical spur curved 

 inwardly at tip and set near the inner angle, the inner part of the 

 tibiae is thickened or laminate inwardly near the apex ; the apical 

 inner spur of the posterior tibiae is very long, and the basal joint of 

 the posterior tarsi is incurved and sharply spinose inwardly ; in the 

 female the anterior tibiae are normal, but the apical spur of the 

 posterior tibiae is longer than the basal tarsal joint. The insects 

 included in this new genus are generally found covered with mud ; 

 they fly at sunset in the autumn or beginning of the spring ; I have 

 found D intrusus occasionally under partly dried cow-dung, but they 

 are generally met with in dung. 



The genus has no foreign representative. 



Key to the Species. 



A~. Elytra with four carinate costse on each side. 



Clypeus of male broadly and deeply emarginate ; basal joint of 

 posterior tarsi in the male very long, strongly arcuate and 

 ending in a very long inner apical spine projecting beyond 

 the apical spur acanthotarsis.
