As far as the brief original description goes this specimen appears to 

 represent Thimberg's species. In the absence of any recent informa- 

 tion on Thimberg's original specimen of this species, the individual 

 in hand may justly be considered the same as coronata until further 

 knowledge disproves or substantiates the association.

CLITUMNIN.E. 

 STELEOXIPHUS' n. gen. 



Type. — S. catastates n. sp. 



A member of the Clitumninae and related to Paraleptynia and Cera- 

 tiscus Caudell, both described from Sapucay. The genus Paraleptynia 

 was based on a male individual, while a female is the only available 

 representative of the new genus. The antennse are shorter than in 

 Paralepttjnia and with some of the segments of different proportions, 

 while the general slender form agrees with that genus. The chief 

 character of Ceratiscus, which was based on a female, is the elongate 

 opercule which is also present in Steleoxiphus, although the form of the 

 latter is by no means as robust, being slender as in Paraleptynia with 

 the limbs not lobed or serrate. The character of the antennae is more 

 similar to that of Ceratiscus than of Paraleptynia. 



Form very elongate; surface glabrous. Head with the eyes very 

 small ; antennae very little longer than the head and pronotum, proximal 

 joint over twice as long as broad, strongly depressed laterad and 

 proximad, second joint more rounded and hardly half the length of the 

 proximal, third joint similar to the second but slightly longer, the 

 fourth to sixth joints similar to the second and from the seventh they 

 evenly increase in length distad. Mesonotum and metanotum (includ- 

 ing median segment) subequal in length; median segment longer 

 than broad, Subgenital opercule produced into a compressed, elongate, 

 hastate process. Limbs slender, unarmed.
