One male, two females. 



The female individuals differ somewhat in size, but both appear 

 referable to this species.

HOLOCOMPSA Burmeister. 

 Holocompsa mtidula (Fabricius). 



1781. [Blatta] nitidula Fabricius, Spec. Ins., I, p. 345. [Surinam.] 



Two females. 



These specimens have a dark brown patch on the caudal section of 

 the disk, and the caudal margin of the pronotum is narrowly suffused 

 with the same color. This pattern of coloration is evidently present 

 in the type of Fabricius as he states: "Thorax ferrugineus, nitidus 

 macula baseos nigra." The golden hairs which are present on the 

 lighter sections of the pronotum are also distributed over the brown 

 area. 

 Holocompsa cyanea Burmeister. 



Two males. 



This species has been recorded from Brazil by Brunner. 



BLABERUS Serville. 

 Blaberus posticus Erichson. 



1848. Blabera postica Erichson, in Schomburgk's Reisen Brit. Guiana, III, 

 p. 580. [British Guiana.] 



One female. 



This specimen is the first of a number of individuals of this section 

 of the genus examined by the author, which appears to fit Erichson's 

 very poor description. The pronotal maculation is confluent laterad 

 with the blackish caudal margin. This character appears to be what 

 Erichson refers to in " Der Halsschild mit spitzer gerundeten Seiten, 

 auf dem Riicken mit einigen kleinen, unbestimmten schwarzen Flecken, 

 dagegen der Hinterrand breit schwarz gesaumt." The figm*e of B. 

 thoracicus given by Saussure and Zehntner represents very nearly the 

 same thing, but a specimen from Costa Rica which I had considered 

 thoracicus ^ has these lateral bars lacking. Kirby's synonymizing of
