The aiitemife are about half the length of the body, the last joint 

 in the male fully as long as seven preceding joints, while in the 

 female it equals very nearly four. 



While closely related to gagatina it seems quite a distinct species 

 by the characters above given. Although the eyes are large in all 

 the species, in this one they are especially so, the portion of the head 

 which usually forms quite a conspicuous border behind the eye is 

 here much reduced. 



Occurs in Georgia, Florida and Louisiana. 



It seems worthy of remark that the species of this genus have one 

 or rarely two setigerous punctures on each side of the abdominal 

 segments placed in the same position as in the Carabidie. 



MELANDRYID^. 



EUSTROPHUS Latr. 



This genus contains but few species, the majority of those de- 

 scribed being members of our fauna. As in the case of Statira the 

 descriptions are scattered, somewhat indefinite, and from their isola- 

 tion very little comparative. As the majority of the species are 

 known in nearly all collections, and as the knowledge of them is 

 purely traditional, it is now proposed to give a few comparative notes. 



In the first place it has been observed that two species differ nota- 

 bly from the others in the form of the prosternum and absence of 

 striae of punctures, it is therefore proposed to divide the genus in the 

 following manner : 



Prosteruuni narrowing to a point aud not prolonjicd behind the coxaj ; elytra 

 with striie of moderate or coarse punctures Eiisiitropliu!^. 



Prosternum prolonged behind the coxae and separating them, the apex somewhat 

 broader; elytra finely, confusedly punctured HolO!<»trO|>lius. 



As restricted above, Eustrophus contains a small number of very 

 closely related species difficult to separate by superficial comparison, 

 and of almost impossible recognition frcmi the descriptions. The 

 following table and notes may, therefore, be of some service. 



The eyes vary in size in two ways. Those species which are dis- 

 tinctly narrowed posteriorly have large eyes very narrowly separated 

 on the front. In the species which are obtuse posteriorly the eyes 

 are smaller and widely separated on the front. 



In all the species but one the middle and posterior tibise have, on 

 their outer edge, numerous transverse ridges, recalling those of Mor-
