 Wien, XL, p. 116. [Porto Alegre, Rio Grande do Sul, Brazil.] 



Paraguay. [A. X. S. Phila.] One female. 



The measurements of the limbs of this specimen are slightly smaller 



than those given by Brunner. 



Cephaloccema costulata Burmeister.

 HaUe, XV, heft I, p. 9, taf. I, figs. 5-7. [Argentina.] 



Sapucay, Paraguay. [Hebard Collection.] One female. 



This specimen is equal to Burmeister's and Brunner's maximum 

 measurements and is considerably larger than two individuals of the 

 same sex from Carcarana, Argentina, in the collection of the Academy. 

 The Sapucay specimen, also, has the rostrum longer than in Burmeis- 

 ter's figure, and in the other specimens examined, but not exceeding 

 the maximum given by Brunner, 



Cephalocoema chapadensis n. sp. 



Types: cJ^ and 9 ; Chapada, Matto Grosso, Brazil. July (6^) and 

 August (?). (H.H.Smith.) [U. S. Nat. Mus., No. 8119.] 



Closely allied to C. costulata but differing in the longer and subequal 

 rostrum, the more marked longitudinal strigse and the heavier antennae. 



Size medium ; surface of the body with distinct longitudinal strigse, 

 weaker on the pronotum than elsewhere. Head elongate, tapering; 

 rostrum of the male about equal to the length of the head, of the female 

 slightly longer than the remainder of the head, tapering in the male 

 with a rather blunt apex, subequal in the female, apex rather blunt 

 and subcruciform when view^ed cephalad; antennse equal to the ros- 

 trum in the male, about two-thirds the length in the female, basal 

 joint slightly less than half the length of the eye; eyes subelliptical ; 

 face very slightly concave. Pronotum elongate, slightly broader 

 caudad than cephalad, limbs inserted very slightly caudad of the 

 micklle; cephalic margin rotund ato-truncate, caudal margin truncate, 

 lateral margins very slightly expanded dorsad of the coxce ; strigse dis- 

 tinct, but not high. Mesonotum and metanotum little broader than 

 the pronotum, strongly strigate. Abdomen with the strigse very dis- 

 tinct; supraanal plate of the male sagittate, apex blunt; subgenital 

 plate of the male compressed, elongate, subequal, the apex obscurely 

 bilobate; supraanal plate narrow, produced, apex bluntly rounded; 

 ovipositor valves strongly compressed, margins unarmed; subgenital 

 plate of the female apically rotund ato-truncate. Cephalic and median 

 limbs subequal in size and form. Caudal femora of the male slightly
