162 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.59. 



more carefully done than that of any other author, and I feel that 

 I have only expanded on the beginning made by him. 



In this paper I have listed all of the species in the National Col- 

 lection and all of the species I have recently studied. Some of the 

 material was borrowed from other museums on the condition that 

 the types be returned. The disposition of the type material is given 

 after each description. 



KEY TO GENERA. 



1. Antennae •with 10 or 11 joints 2 



Antennae with 12 or more joints 4 



2. Body cylindrical, elongate oval; second intercubitus wanting, therefore only three 



cubital cells; antennae in male with 11 joints; first flagellar joint elongate, the 



others dilated at apex; palpi short, the maxillary 4 jointed Tristegus Konow. 



Body robust, oval; second intercubitus present, therefore with four cubital cells. .3 



3. Antennae with 10 or 11 joints of nearly equal size; a single joint of the flagellum 



narrowed at base and dilated apically; hind part of pronotum more or less 



swollen Camptoprium Spinola. 



Antennae of male 10 jointed, of female 10-11 jointed; a single joint of flagellum is 

 conical in the female and funnel-shaped in the male; joints of female some- 

 times compressed Decameria Lepeletier. 



4. Maxillary palpi 4 jointed, labial palpi 3 jointed; antennae of male biramose, of 



female serrate; second recurrent usually received in second cubital cell, but 

 sometimes interstitial or at extreme base of third cubital cell. 



Lophyroides Cameron. 

 Maxillary palpi 5 jointed, labial palpi 3 jointed; antennae simple with well- 

 defined joints in both sexes; second recurrent received by the third cubital 



cell Ueteroperreyia Schrottky . 



Maxillary palpi 2 jointed, labial palpi 1 jointed; antennae simple with well- 

 defined joints in both sexes; second recurrent usually received by the second 

 cubital, but sometimes interstitial or received at base of third cubital. 



Perreyia Brulle. 

 Genus TRISTEGUS Konow. 



This genus was described by Konow and is known only in the 

 male. The antenna is simple; the head small; and both recurrents 

 are received by the second cubital cell. 



Genus CAMPTOPRIUM Spinola. 



No species which could be placed in this genus is available, but, 

 as previously suggested, there are certain characters which would" 

 indicate that it is not properly placed in the Perreyiinae. The fol- 

 lowing notes from tho original description may be useful: Palpi fili- 

 form, the maxillary 6-jointed, the labial 4-jointed; third antennal 

 joint of male longer than fourth and fifth combined; second and 

 third cubital cells each receiving a recurrent vein; head transverse 

 as wide as thorax. 



Genus DECAMERIA Lepeletier. 



I have followed previous authors in accrediting this genus to Lepe- 

 letier; but inasmuch as there is some doubt as to the correctness of 

 this, I have not followed my usual custom and named the subfamily
