6 NEW NEOTROPICAL EVANIIDAE (hYMENOPTERa) 



Differs from C. manni Brucs in having petiole lonsitudinall}^ 

 carinate and space behind the ocelli punctate. It differs from 

 C. longist'ila Kieffer principally in the comparative length of 

 petiole, tibial spurs, and the prominence of parapsidal grooves. 



One specimen, the holotype, from Igarape-Assu, Brazil, col- 

 lected on July 16, 1919. 



This species is named in honor of Dr. Alexander D. Mac- 

 Gillivray. 



HYPTIA llliger 



There are six specimens of the genus /////>/ /a in the collection, 

 representing four species. Hyptia as here used is equal to 

 Hyptia of Kieffer (1912), in which there is only one closed cell 

 in the front wing. It may be noted that Kieffer in his mono- 

 graph has placed the species riujosa Cameron, cameroni 

 Schletterer ( = dorsaUs Cameron), and guatemalensis Cameron 

 in the genus Brachygastcr. All three were originally descril)ed 

 by Cameron as Eranio. Bradley (1908) referred these species 

 to the genus Hyptia. This was also the view of Kieffer in 1903, 

 where he says that these species belong to the genus Hyptia, 

 but does not give any reason for this interpretation. If the 

 colored figures illustrating Cameron's work are correct, they 

 show that the fore wings of rugosa and cameroni each possess 

 but a single closed cell, and under Kieffer's own generic key 

 run to Hyptia. Likewise there is nothing in the description 

 of these species to suggest that they have three closed cells in 

 the fore wing, as have the members of the genus Brachygastcr. 

 These species should therefore be placed under Hyptia. Al- 

 though guatemalemsis Cameron is not figur(Hl in the Biologia 

 Central-Americana, according to the description it may be either 

 a Brachygastcr or Hyptia. However, as it is keyed through 

 the same alternative by Cameron as rugosa and cameroni, the 

 prol)a})ilities are that it likcnvise belongs to the genus Hijptia. 

 Kieffer in the work cited above (1912), also places Cameron's 

 species crassa under the genus Evania. Bradley, in 1908, con- 

 sidered this species as belonging to Hyptia, as did Kieffer in 1903. 

 Crassa is figured in comuH'tion with Cain(>ron's work, and foi- 

 the same reason as stated above for rugosa and cameroni, this 

 speeies ran not belong to the genus Evania. Crassa, as figured,
