Dichroplus punctulatus Thunh. 



This widely distributed tropical American species is représentée! 

 hy a pair taken during September at the same locality as the pre- 

 ceding. They are quite typical. 



Osmilia coelestis Biirm. 



Tiiere are 40 spécimens of tlie genus Osmilia in the collec- 

 tion and they ail appear to belong to the one species that I hâve 

 labeled as Burmeister's coelestis which seems to differ from the 

 violacea of Thunberg from Panama and eastern Brazil. They 

 were taken at the same locality and diiring the same period as the 

 Dichroplus peruvianus. 



This genus needs revision as the species seem to be mimerons 

 or eise quite variable. Représentatives occur throughout tropical 

 America and the adjoining portions of the temperate zones. 



Rhytidichrota peruviana, sp. n. 



Insect fairly robust, fusiform, the abdomen small, rapidly 

 tapering. 



General color dark brownish-olivaceous above; below flavous; 

 the anterior and middle legs, bind tibiae and apical half of maie 

 abdomen greenish-yellow. Basai half or two-thirds of inner and 

 outer disks of bind femora blood-red, beyond strongly infuscated. 



Head, thorax and basai abdominal segment strongly and coar- 

 sely punctulate, the first sparsely, the others i)rofusely, the surface 

 sparmgly but rather lengthily hirsute. Entire insect quite decidedly 

 glabrous. Head of moderate size, about as wide as the anterior edge 

 of the pronotum into wliich it is set nearly to the hind margin of the 

 eyes the latter quite prominent, broadly oval or elliptical, nearly as 

 niuch rounded at theü- upper as at their lower extremity, longer than 

 that portion of the cheek below them, separated at the vertex by 

 a space about one-half (j>) or two-thirds ($) of the width of the 

 frontal Costa between the antennae; the fastigium ratlier stongly 

 depressed, sulcate, a little лvider than long; frontal costa quite pro- 

 minent between the base of the antennae where it is sparsely but 

 coarsely punctate, below less prominent, quite deeply sulcate and 

 provided with prorainent lateral walls, eontinuous to the clypeus; 

 lateral facial carinae streng, divergent below, reaching from the 

 lateral ocelli to the middle of the outer face of the mandibles. Occi-
