CARABIDAE. 5V 



full discussion of the cliaracters which serve to divide the species 

 in subgenera and lower groups — the trifid anterior tibial spur, 

 the spur broader at middle and the slender spur. In two species, 

 hai-paluides and opaculus, the first joint of the anterior tarsus of 

 the female is dilated, and in the former that joint is somewhat 

 prolonged under the second. 



Xestonotus. — Anterior tarsi broadly dilated in the male, the 

 first four joints densely si)ongy pubescent beneath, middle tarsi 

 with four joints less widely dilated and spongy pubescent beneath, 

 the first entirely glabrous, posterior tarsi slender and long. Elytra 

 with one dorsal puncture. The ligula is rather narrow and 

 parallel, the paraglossa^ broad and a little longer than it. 



Comparing the differences between the ligula and paraglossae 

 with those observed in Harpalus there does not seem any valid 

 reason for retaining the genus apart from AnisodacU/lux, and the 

 .species will find a suitable position between the amaroides and 

 seinceus groups of that genus. 



Ampiiasia. — Here the characters are essentinlly those of ^??2.so- 

 dactylus sericeus. The paraglossse are similar in form to Aniso- 

 dactylus, and merely a little longer. 



EuRYTRiCHUS — The sexual characters and those derived from 

 the posterior tarsi are precisely those of Anisodactylus ccenux 

 and Isetus. The paraglossae are a little broader than in typical 

 Anisodactyli. 



Spongopus. — The ligula and paraglossae are intermediate in 

 structure between the typical Anwodactylus and Xestonotus, and 

 the ligula is free for a greater distance at tip. The sexual cha- 

 racters are those of the amaroides group. The posterior tarsi 

 are however slender. The elytra being punctulate and with a 

 single dorsal puncture, this species forms an intermediate between 

 the discoideus group and sericeus. 



From the above remarks it would appear that these genera are 

 inseparable from Anisodactylus. 



[t is worthy of note that we may have in Anisodactylus more 

 than one setigerous puncture at each angle of the clypeus, while 

 in most CarabidaB there is but one, and even this may be lost.
