A TEKMITOPIIILOUS BEETLE OF THE GMNUS COHOTOCA. 105 



J. S. Schiodte^ has given a careful definition of the genus 

 Corotoca, and also concise diagnoses of two species, C. 

 melantho and C. phylo, both from Brazil. 



These diagnoses are quoted below in order that they niay 

 be compared with the brief description of the new species 

 which is now given, pending a detailed account of the anatomy 

 of the insect, which it is proposed to publish hiter. 



I have pleasure in associating this interesting species with 

 its discoverer, Dr. Conrad Akerman. 



"1. Corotoca melantho SchvkUe. 



" Fusca, fronte foveolata, pronoto multifoveolato, disco 

 bituberculato : tibiis posterioribus fusiformibus, fuscis : scutis 

 ventralibus segmenti quarti (juiiiticjue transversis. — Mas, 

 Fern. 



" Long, a fronte ad apicem segmenti secundi abdominis, 

 2^-3 millim. 



"2. Corotoca phylo Schiodte. 



" Fusca, vertice foveolato, pronoto multifoveolata-, disco 

 trituberculato : tibiis posterioribus linearibus, nigrofuscis : 

 scutis ventralibus segmenti quarti quintique subquadratis. — 

 Fem. 



" Long, a fronte ad apicem segmenti secundi abdominis, 

 2^-3i millim." 



3, Corotoca akermani s-p. n. 

 Brown, forehead or vertex not pitted, occiput Hat or 

 slightly concave, not tuberculated ; pronotum smooth, except 

 for a very shallow and rather wide and inconspicuous median 

 groove extending along the postei'ior three-quarters of its 

 length ; posterior tibia) rather slender, straight or slightly 

 curved, not fusiform, but rod-shaped ; sternites of the third, 

 fourth, fifth, sixth and seventh abdominal segments appear as 

 five isolated, uniform, narrow, transverse, brown strips of chitin
