This species is readily distinguished from the preceding by its 

 decidedly smaller size, somewhat broader form and darker buffy 

 brown general coloration. The tegmina are seldom much suffused 

 beyond the apex of the humeral trunk, though sometimes heavily 

 so, but a broad transverse median band, such as is found in colos- 

 seus, never occurs. 



The immature condition of this species is more convex and has 

 the pronotum and lateral portions of the dorsal surface much less 

 lamellate than in immatures of colosseus, in general form very 

 similar to immature examples of the genus Archimandrita. 



EUBLABERUS new genus 

 1894. Blahera Saussure and Zehntner, Biol. Cent. Am., Orth., i, p. 117. (In part; 

 species placed in section "a" of key for the genus.) 



The present genus includes hiolleyi (Rehn), posticus (Erichson). 

 sulzeri (Guerin), distanti {Kirhy) , femorata (Scudder) and im?nacula 

 (Saussure and Zehntner), which, in our opinion should be arranged 

 in the order here indicated. 



Genotype: Eublaberus hiolleyi [Blaber us hiolleyi] {Rehn).^^^ 



The genus is closely related to Blaherus, but differs signally in a 

 number of features, given in the following description, which give 

 all of the species a distinctly different facies. 



Generic Description. — Interocular space wide to very wide; wide 

 only in certain species of Blaherus. Antennae heavy, incrassate, 

 moderately pilose except in proximal portion; distinctly more 

 slender in Blaherus, with pilose condition less decided. Pronotum 

 with lateral margins showing an appreciable angulation mcsad or 

 meso-cephalad, or with point of greatest convexity meso-cephalad; 

 in Blaherus the lateral margins of the pronotum never show any 

 angulation, the point of greatest convexity being mesad or meso- 

 caudad. Pronotum with a broad blackish bar on caudal margin. ^^'^ 



134 \Yjj select this species as genotype, owing to the fact that both original description 

 and figure are better than for any other species here included. See Proc. Acad. Nat. Sci., 



1905. P- 792, fig- I, (1906). 



"5 Such marking is found only in Blaherus Jralcrnus Saussure, among the species of 



that genus at hand.
