refers material from Cacagualito, Colombia; Sao Luiz de Caceres, 

 Matto Grosso, Brazil, and British Guiana to it, while Bugaba, Pan- 

 ama is given by Saussure, in the Biologia, as another loealitj^ The 

 form of the whole thorax of the male is so remarkable that its isola- 

 tion from the other members of the genus is quite marked.

Para. (C. F. Baker.) One male. 



We have referred this specimen to conspersa although it shows 

 several features of difference, which, however, we feel are due to in- 

 dividual or sexual variation, lack of note or over-emphasis in the 

 original description. In our specimen we see no distinct indication 

 of the ridge, "which separates this region {i. e., depressed section of 

 the vertex) from the front." There is, however, a slight elevation 

 covering the base of the inter-antennal protuberance, which may be 

 the feature referred to by Bruner. The other feature is that the 

 whole occiput caudad of the transverse arcuate depression is solidly 

 mars brown. 



Anaxipha simulacrum n. sp. (PI. II, figs. 56-59.) 



The slender form, the blackish antennae and the shape of the ceph- 

 alic tibiae and of the ovipositor are quite characteristic of tliis very dis- 

 tinct species, which has, at a glance, a Cyrtoxiphine appearance. 

 The head and palpi, however, are Anaxiphine in character. 



The species is not closely related to any of the other forms known 

 to us. 



Type: 9 ; Igarape-assii, State of Para, Brazil. (H. S. Parish.) 

 [Acad. Nat. Sci. Phila., Type no. 5340.] 



Size very large (for the genus) : form moderatelj' elongate, slender, 

 terete: surface of body moderately shining, with numerous hairs, 

 the marginal ones of the pronotum, particularly laterad, elongate 

 and curved. Head in general vertical, its axis slightly retreating 

 ventro-caudad, its greatest longitudinal length slightly less than the 

 greatest depth (including the mandibles) ; in lateral view the occiput 

 is well arcuate caudad of and between the eyes, thence very strongly 

 arcuate-declivent to the inter-antennal region, which is rounded 

 obtuse-angulate, the ventral section retreating to the clypeal suture; 

 when seen from the dorsum the occiput is broad, very broad behind 

 the eyes, the narrowest portion of the interocular section slightly 

 less than half the width of the head at the caudal margin of the 

 eyes, the least interocular width subequal to the transverse width
