2. CHRYSOPLATYCERUS HOWARDII Ashmead. 



C hr y SO platy cents hoicardii Ashmead, Proc. U. S. Nat. Mus., vol. 22, p. 

 405, 1900. 

 This species was described from two females which were supposed 

 to have been collected in Mexico. Mr. Gahan examined the types for 

 me in the United States National Museum and reported that in regard 

 to all structural characters they were practically identical with 

 splendens. The male of this species remains unlmown. 



3. CHRYSOPLATYCERUS FERRISI, new species. 



Female. — Head proportionately a little larger and wider than in 

 splendens^ being somewhat wider than the thorax, the dorsal surface 

 well rounded, the anterior area between the eyes and the transverse 

 carina without the strongly developed impression found in splendens; 

 frontovertex about two and a half times longer than the width in the 

 ocellar region, distinctly but not greatly widening anteriorly; ocellar 

 angle considerably less acute than in splendens^ the distance between 

 the posterior ocelli being only slightly less than the length of the 



other sides of the 

 triangle, the pos- 

 terior pair almost 

 touching the eyes 

 and removed a little 

 more than their own 

 diameter from the 

 occipital margin; 

 eyes somewhat 

 larger than in splendens^ less protuberant, becoming a little wider 

 anteriorly, their surface glabrous; face nearly as in splendens but the 

 transverse carina more deeply curved, thus forming almost a semi- 

 circle, the prominence between the antennae slightly and uniformly 

 convex, as long as wide, not abruptly and obliquely inclined forward 

 anteriorly as in splendens^ and its upper or posterior margin well 

 rounded. 



Antennae (fig. 1) inserted far apart and not distant from the oral 

 margin; scape laminately expanded and about a half longer again 

 than wide, its base (excluding the radicle joint) slightly obliquely 

 truncate, the apical end rounded, the dorsal part abruptly folded 

 over at more than a right angle with the ventral expansion, thus 

 forming a narrow flattened surface above, widest at the apex and grad- 

 ually narrowing toward the base, and also forming a groove on the 

 outer surface above to receive the pedicel and part of the flagellum ; 

 pedicel in the form of a three-sided pyramid, like that of splendens in 

 shape, but proportionately not more than one-half as large, its apex 

 truncate, whereas this part is deeply concave in splendens; flagellum
