ASHMEAD : CLASSIFICATION OF THE CHALCID FLIES 443 



spot on the lateral lobes of the mesothorax, two lines on the middle lobe anteriorly 

 for about two thirds its length, a spot at apex of hind coxse above, a spot at apex of 

 hind femora and the sheaths of the ovipositor, black. The abdomen is fusiform, 

 longer than the head and thorax united, the petiole being only twice as long as 

 thick. The hind femora are armed with one large tooth, followed by about sixteen 

 minute black teeth. 



West Indies : Trinidad. One specimen. 



Named in honor of Mr. Claude Fuller. 



Spilochalcis corumbensis, sp. nov. 



Female. — Length 9 mm. Yellow ; the occiput, the flagellum, a minute dot 

 towards apex of the scutellum, the suture across its base, a spot on the lateral lobes 

 of the mesothorax, a loop on the middle lobe anteriorly, a small spot in the meso- 

 pleural furrow, and the extreme apex of hind coxse, black. 



The abdomen is fusiformly pointed, longer than the head and thorax united, 

 the petiole very short, transverse. The hind femora are armed with fourteen or 

 fifteen minute teeth. 



Brazil : Corumba, in April. One specimen. 



Spilochalcis chapad^e, sp. nov. 



Female. — Length 4.3 mm. Yellow ; the occiput, scrobes, flagellum, a median 

 longitudinal line on scutellum and the suture at base, a broad line along the inner 

 margins of the lateral mesothoracic lobes, a loop connected with a short median line 

 from the base of the scutellum, on the middle lobe, the mesopleural furrow, the 

 apex of the hind coxse, a small oblong spot on disk of the outer face of the hind 

 femora and a spot at apex, and most of the body of the abdomen, black. 



The abdomen is conic-ovate, the petiole at least thrice as long as thick. The 

 hind femora are armed with fourteen or fifteen minute black teeth. 



Brazil : Chapada, in April. One specimen. 



Spilochalcis brancensis, sp. nov. 



Female. — Length 6 mm. Colored and marked very nearly as in S. cliajpadse, ex- 

 cept that the black spots on the lateral lobes of the mesothorax are shorter, the scu- 

 tellum has a wedge-shaped black spot at the middle, the hind coxEe have a rounded 

 spot above, while the hind femora have two black spots. 



Structurally, however, there is no resemblance : The head in front is deeply 

 semicircularly emarginate for the reception of the antennae ; the antennae are sepa- 

 rated at base by a sharp carina or spine ; the hind coxae are not nearly so long ; the
