15 PKOCEEDINGS OF THE NATIONAL MUSEUM. vol.61. 



description of Allapanteles ceckliptae Brethes, upon AYhicli the genus 

 Allapanteles was based, likewise agrees absolutely with Apanteles 

 Foerster. 



For a key to the North American species of this genus, see Pro- 

 ceeding of the United States Natural Museum.^*' At the time that 

 paper was prepared I had not seen the types of Cresson's four West 

 Indian specimens hyalinus, pinos, fiaviventris, and marginatiis, and 

 I accordingly placed these in my key on the basis of the original 

 description. Recently I have examined this type material at the 

 Philadelphia Academy of Sciences, and I find hyalinus, pinos, and 

 flaviventris to fit into the places assigned them in my table to species. 

 But marginiventrls runs at once to grenadensis Ashmead, and after 

 studying the seven specimens constituting the type series of the 

 former, I have definitely concluded that the two names are synony- 

 mous; grenadensis Ashmead, then, must be suppressed.

 Type.— In the Philadelphia Academy of Sciences. Cotypes of 

 gi^enadensis and type of harnedi in the United States National 

 Museum ; other cotypes of grenadensis are in the British Museum. 



This species is widely distributed through the Southern States and 

 the West Indies. 



APANTELES CAUDATUS, new species. 



Runs to category G9, in my key to species referred to above, and 

 is very similar to cinctifoi^mis Viereck, from which it is at once sepa- 

 rated by the darker abdomen, the longer, curved, black ovipositor 

 sheaths of the female, and the enormous claspers of the male. 



Female.— L^iv^h., 3.5 mm. Face broader than long, sparsely, 

 shallowly punctate and shining ; vertex, temples, and cheeks weakly 

 punctate, strongly shining ; antennae slightly shorter than the Ijody ; 

 mesoscutum covered with minute shallow punctures, shining, almost 

 polished posteriorly ; scutellum practically impunctate and polished ; 

 mesopleurae weakly punctate anteriorly, polished, and shallowly 

 foveate posteriorly; propodeum closely punctate, with a median 

 longitudinal carina: stigma large, very slightly shorter than the 

 metacarpus; radius and first intercubitus subequal in length and 

 meeting in a rather strong angle ; posterior coxae smooth and shining,
