angles, and four on the posterior margin of the eighth ; narrow, 

 deep golden brown lateral bands on segments one to seven, widely 

 broken by clear posterior angles, and slightly projecting into the 

 adjacent anterior segments ; eighth segment very long, as long 

 as the first, with nearly straight, converging sides and completely 

 obscured l)y the transverse, golden brown band; ninth segment 

 short, and almost transverse posteriorly, uniformly pale golden, 

 with one short hair on each side of the tip ; segments one to seven 

 almost completely obscured by deep golden brown, transverse 

 bands, darker medially and in posterior segments, and separated 

 transversely by clear sutures; a clear pustule at the spiracles on 

 segments two to seven and a single long hair on the posterior 

 margins of segments two to six, just within the lateral bands. 



A single female collected on Trogoii caligatiis, at Juan Vinas, 

 Costa Rica, March, 1902. This species is easily recognized by 

 the rounded front, with concave sides, completely encircled by 

 the antennal bands ; by the length and shape of the eighth seg- 

 ment of the abdomen and the presence of the broad, transverse 

 abdominal bands.
