PARENIACA, ne-w genus. 



Belongs to the tribe Dirhiniiii and has the habitus of Eniaca, from 

 which it differs by having a pair of small subtriangular teeth below 

 the large cornutions of the head (see fig. 1) ; funicle with eight joints, 

 the first shorter than the pedicel, often subquadrate and therefore 

 more or less ring like. 



Type. — Pareniaca schwarzi Crawford. 



This genus differs from DirJiinus in having the head 4-cornuted 

 and in the pedicel being longer than the first segment of the funicle ; 

 it differs from Hontalia in habitus, in the nonmetallic color, in having 

 the ovipositor not exserted, in the absence of an elongate spine ven- 

 trally on the first abdominal segment (petiole), etc.

 tinge, head and thorax coarsely rugoso-punctate; antennse, fore and 

 mid legs, except coxae, rufous; pedicel longer than second joint of

 than the second joint, about as long as the 

 third joint of funicle ; fourth joint longer than 

 Inroad, fifth and following subquadrate ; wings

 siDE VIEW OF HEAD OF FE- jomcn (pctiolc) trausvcrse, with four dorsal 

 carinse between the lateral carinate (viewed

(HONTALIA) PAREOTACA RUFICORNIS (Cameron). 



In this species the first abdominal segment (petiole) is slightly longer 

 tlian broad and has four dorsal carinas; the second segment has about 

 six or seven carinas wliich do not extend half the length of the seg- 

 ment. The species is readily distinguished by the infuscate fore 

 wings with subhyaline spots on the apex and on the front and pos- 

 terior margins. In the United States National Museum there is a 

 male from Cacao, Trece Aguas, Alta Vera Paz, Guatemala (Schwarz
