CUCUJID^: 117 



The name of the Central American species described by Dr. 

 Sharp as puncticollis being preoccupied, as shown above by puncti- 

 collis Newm., it becomes necessary to change it, and I would propose 

 sharp! (nom. nov.) as a substitute. 



Subfamily 



The variety of structure comprised at present within the limits 

 of this subfamily necessitates the organization of many tribal 

 groups, some of which point toward the Passandrinae, such as- 

 Prostomis, with its elongate genae, and others toward the Silvaninae. 

 Based upon material now at hand the following tribes seem worthy 

 of definition. 



PROSTOMINI. The typical species is Prostomis mandibularis 

 Fabr. P. americana Cr., is very closely allied but is not the same 

 as mandibularis, differing chiefly in the notably prominent, semi- 

 globular eyes; in the European species the eyes are only moderately 

 prominent; this difference becomes very apparent when series are 

 compared. As in all the genera allied to the Passandrinae, the species 

 frequently resemble each other very much, though nevertheless 

 distinct. 



NARTHECIINI. Chiefly distinguished from the following tribes 

 by the produced and prominent median part of the front, large 

 head, with moderate and very advanced eyes, short silvanoid clavate 

 antennae and open anterior acetabula. The tarsi are 4-jointed, 

 with the last joint very long as in Monotomidae. In various ways 

 the tribe has affinities with the Laemophloeini, through the head 

 and eyes of Parandrita and by way of the short clavate antennae of 

 Dysmerus and Leptophlceus angustulus Lee. It will be noted that 

 when the median part of the front is advanced in the Laemophloeini, 

 as in Rhinomalus and Rhinophlceus, the frontal margin remains 

 transverse and truncate, while in Narthecius there is a more or less 

 acute projection medially. This cribe will also include Paraphlceus 

 Sharp. 



LATHROPINI. Including, so far as known, only the minute species 

 belonging to the genus Lathropus Erichs., reminding us of Laemo- 

 phloeini in bodily habitus but having small and very short antennae, 

 with strongly though loosely 3-jointed club as in Hypocoprus. The 

 anterior coxae are very small and the acetabula broadly closed. The
