63. POLYCYRTUS (POLYCYRTUS) TRICOLOR BruUe 



Mesostenus {Polycyrtus) tricolor Bbull6, Hist. Nat. Ins. Hym., vol. 4, 1846, 



p. 209, female. 

 Mesostenus tricolor Cbbsson, Proc. Ent. Soc. Phila., vol. 4, 1865, p. 29, 



female. 



A single female specimen in the United States National Museum 

 appears to belong here. It was taken at Soledad, Cuba, on June 8, 

 1925, by George Salt. This specimen is the basis for the following 

 notes. 



Very similar in general form and structure to the two preceding 

 species, but the frontal horn has two deep pits at its base, the occipi- 

 tal carina is distinctly complete to hypostomal carina, the anterior- 

 lateral margin of pronotum is sharply angulate below the middle, the 

 mesopleurum is obliquely striate in the middle and the metapleurum 

 coarsely, densely punctate, and the propodeum is very much like that 

 of hwnerosus with the apophyses even lower. 



In color it is very distinct, differing from both of the other species 

 in having the scape below and apex of horn white ; thorax entirely 

 black and white, discal white lines of mesoscutum extending nearly 

 the entire length of inner margins of lateral lobes, pleura entirely 

 white except along sutures; propodeum black and white with black 

 pattern much as in paululus with entire basal area black and three 

 longitudinal black stripes, the lateral ones, however, much broader 

 than in paululus; abdominal color pattern much as in humerosus; 

 legs ferruginous with apices of tarsi black. 



POLYCYRTUS MANCUS Crcsson 



Polycyrtus mancus Cbesson, Proc. Acad. Nat. Sci. Phila., 1873, p. 145, 

 female, male. 



A male cotype in the United States National Museum differs from 

 the description of the species in having the mandibles black and the 

 petiole yellow dorsally with a black line on each side.
