POLYCYETUS. 243 



32. Polycyrtus curviventris. (Tab. X. fig. 28, $ .) 



Rufus ; antennis, capite, feraoribus posticis, abdominis dorsis pro parte terebraqne, nigris ; annulo antennarum y 



clypeo, labro mandibulisque, albis ; alis byalinis, fere fumatis, nervis nigris. 5 . 

 Long. 21-22 millim. ; terebra 11 millim. 



Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion). 



Smooth, shining, impunctate, sparsely pilose. Lobes of the mesonotum well deve- 

 loped. Frontal spine conical, short. Transverse keel on the metanotum slightly 

 curved backwards in the middle. Tubercles longish, slightly curved, of nearly equal 

 thickness throughout, rounded at the apex. Petiole not defined from the postpetiole. 

 Apex of the abdomen clavate, oblique. Petiole entirely reddish ; the other segments 

 black above, the second and third broadly red at the apex. Areolet longer than broad, 

 dilated at the apex, closed, the recurrent nervure interstitial. 



The largest of the Central American species. 



33. Polycyrtus xanthothorax. (Tab. X. fig. 12, $ .) 



? Mesostenus xanthothorax, Brulle, Hist. Nat. Ins. Hymen, iv. p. 213 ( <$ ) ; Taschenberg, Zeits. f . d. 

 gesaromfren Naturwiss. xlviii. p. 77 ( ? ) \ 



Hab. Panama, Bugaba 800 to 1500 feet (Champion). — Beazil \ 



As I am not quite certain that the Bugaba example (a female) is identical with the 

 species described by Brulle and Taschenberg, I give a full description of it : — 



Antennae scarcely so long as the body, black, a broad white ring beyond the middle ; 

 moderately stout, covered with a microscopic pile. Head black, the labrum, clypeus, 

 and mandibles white ; frontal spine shortish, thick, conical. Thorax red ; pronotum in 

 front, and the mesonotum (but not the scutellum), black. Lobes of the mesonotum well 

 developed. Metathorax longish, with a nearly gradual slope to the apex ; the centre 

 very slightly hollowed, and there is a shallow furrow between the tubercles, which are 

 short, being not more than twice as long as wide. The upper transverse keel straight ; 

 the other obsolete. Abdomen black, the upper side of the postpetiole black ; the 

 second segment broadly white at the apex, the other segments narrowly white, the 

 ventral surface obscure white. The apex of the abdomen decidedly clavate, compressed 

 laterally, the extreme apex oblique ; the ovipositor issuing from the lower side and 

 projecting upwards, its sheath black and hairy, about half the length of the abdomen. 

 Petiole longish, slender ; second segment nearly as long as the petiole, and longer than 

 the following segments together. Legs reddish ; posterior femora, and the greater part 

 of the hinder trochanters, black ; posterior tibiae and tarsi whitish yellow, the apex of 

 the latter black. Wings scarcely so long as the thorax and abdomen together, hyaline ; 

 areolet small, a very little longer than broad, the apical nervure bullated, the recurrent 

 nervure recurved in the middle. 



Brulle describes the tubercles in his species as " longues et arquees," and Taschenberg
