An excellent trap for small Silphldae, Catops, Colon, etc. 



is made by putting a rabbits foot or any similar object in an ale 

 bottle and burying it up to the mouth in earth. These small noc- 

 turnal species will in the pursuit of the odorgiving food fall into 

 the bottle, from which they cannot escape. 



Leconte. 



This note, just communicated to us by Dr. Leconte is very welcome, 

 as these little Silphidae always were scarce and very poorly represented in 

 most collections. 



On the randy tanks of the Delaware and its tributary the 

 Callicoon River I collected large numbers of Omophron [ 72 and 78 

 Crotch's list ] Dyschirius [ 224. 227 J Clivina [ 261 ] Schizogenius [276] 

 Piatyum, Taehys [1127, 1129. 1145. 1148. 1156] Bembidium [ 1026. 

 1029a. 1034, 1035. 1036. 1037. 1042. 1057. 1090. 1095. 1096. 1110. 

 1116. ] Heterocerus and other small species, by pouring water over 

 the small holes in the sand and on the plants growing at the edge 

 of the water. Very often I saw them running out of their retreats 

 by the hundreds. 



In this way during one hour one may secure a large quantity. 

 Clivlnxand Dyschirius are in the holes in the sand, Omophron and 

 Heterocerus under the plants, the rest are found under the small 

 stones on the banks. Schaupp. 



COLEOPTEROUS LARVAE of TENEBRION1DAE 



IN GENERAL. 



[n studying the larval states of Tenehrionidae we find that there 

 is scarcely a coleopterous family whose members are homologically 

 so closely allied and correlatively alike, that I venture to say they 

 are all retiaoeable to scarcely three typical larval forms. 



The first type comprises that of Tenebrio [Tenebrionellus Or. J 



— having homogenous corneous segments of cylindrical string- 

 shape, the stigmata are situated under the overlapping tergal fold 

 [ in what Lacaze Duthiers calls the Pleurites ] . 



The second type comprises that of Boletophagtcs & Boleiotherus 



- a more compact form with only the prothoracic segment corneous 

 and abdominal segments slightly arcuate. The dorsal segments do 

 not overlap, forming a marginal bead [ wulst] , above which [ on 



the tergal part of ihe segment] the abdominal stigmata are situated. 

 The third type comprises that of Pentaphyllus. Clypeus not en- 

 tirely separated, mandibles more strongly dentate, terminal joint 

 of labial palpi large and truncate, pygidium without penicilli.
