ii. Transverse humeral nervure received before the transverse basal nervure in the 

 anterior humeral cellule ; head strongly transversely striolated. 



4. Spathius striatifrons. 



Niger, palpis, apice antennarum pedibusque albidis, scapo antennarum, ore tarsisque posticis testaceis, coxis 

 posticis (apice excepto) apiceque femorum posticorum nigris ; alis fuscis, stigmate fusco cum basi et apice 

 pallidis. $ . 



Long. 5-5 millim. ; terebra 1-5 millim. 



Eab. Panama, Bugaba 800 to 1500 feet (Champion). 



Antennae longer than the body, microscopically pilose, the scape on the underside 

 and the apex broadly white. Head black, the orbits narrowly and the mouth tes- 

 taceous ; palpi white ; face shining, transversely striated ; vertex strongly transversely 

 striated ; front somewhat depressed in the middle, punctured. Mesonotum aciculate, 

 opaque ; scutellum shining, impunctate ; pronotum strongly striolated ; mesopleurse 

 shining, the fore part aciculate, the top longitudinally striolated ; metathorax strongly 

 longitudinally striolated throughout, without areee, but with two lateral keels, the 

 inner keel (where the slope begins and ends) bearing a tubercle. Petiole narrow, 

 curved, finely longitudinally striated, and with a fine keel on either side ; the rest of 

 the abdomen shining, impunctate, the apex testaceous. 



The position of the transverse humeral nervure forms a ready means of separating 

 this from the preceding species. S. striatifrons also differs in the petiole being pro- 

 duced on either side not far from the base.

DOEYCTES. 



Doryctes, Haliday, Ent. Mag. iv. p. 43 (1836). 



The two species included here certainly belong to the " Doryctides " of Forster, but 

 they do not quite agree with Doryctes as defined by him, inasmuch as the hind coxse 

 can scarcely be said to be " angularly produced in front ; " while they differ from Coeloides, 

 Wesm., in the suturiform articulation being obsolete, and in the transverse humeral 

 nervure not being interstitial. 



1. Doryctes strongylogaster. (Tab. XV. fig. 21, $ .) 



Nitidus, rufus ; capite, antennis, profchorace, abdominis segmentis 4°-7 m pedibusque, nigris ; alis fuscis. $ . 

 Long. 13 millim. ; terebra 11 millim. 



Eab. Panama, Bugaba (Champion). 



Antennae fully one half longer than the body, filiform, sparsely microscopically pilose ;
