pronotiim presents two conical and acutely raised tubercles, separated 

 from each other; pronotal lateral callus developed into a short and 

 obtuse tubercle; number and disposition of the elytral tubercles like 

 that of C. hispidulus, but tubercles higher and more acute; some of 

 them resemble small spines; first abdominal segment laterally with 

 two tubercles more acute than the corresponding ones in C. hispidulus 

 hispidulus. 



Measurements. — Length 5.0 mm., diameter 3.8 mm. 



Type. — In the collection of the Zoological Museum, Copenhagen, 

 Denmark. 



Distribution oj material. — Brazil: Lagoa Santa (1 holotype female, 

 Reinhardt collector, in the collection of the Zoological Museum, 

 Copenhagen, identified as "hispidula Klug") ; Rio de Janeu'O (1 para- 

 type female, Kraatz collector, in Deutsches Entomologisches Institut, 

 Berlin, identified as "Chlamys sp., Bryant det.")- 



Remarks. — The present very peculiar species resembles an extraor- 

 dinarily developed example of C. hispidulus, but since I have not 

 seen forms transitional between these species, I prefer to consider it a 

 separate entity, at least for the time being.
