the apical part of the antennae a distinctly serrated outline inter- 

 nally), and their comparative shortness, distinguish it at once 

 from all the above and from all previously described species of 

 Tomyris. T. cenea, however, makes a manifest approximation in 

 this respect and T. ohscura shows indications in the same direction. 

 I have seen only one sex (apparently female) of this species.

Tomyris difficilis, sp.nov. 



Oblonga ; minus nitida ; asnea, vix cupreo-micans ; labro, 

 mandibulis, palpis, antennis (articulis ultimis apice nigricantibus 

 exceptis), pedibusque, flavis ; coipore supra sat sequaliter confer- 

 tissime subtiliter aspere punctulato, breviter sat confertim argenteo- 

 pubescenti, subtus antice confertim aspere (postice sparsius vix 

 aspere) punctulato, minus dense pubescenti ; oculis sat fortiter 

 convexis ; elytris postice minus abrupte declivibus ; prothorace 

 transversim impresso ; antennis corpore sat brevioribus, articulis 

 6-10 paullo compressis elongato-subconicis, 3° et 4° inter se 

 sequalibus. [Long. 1§ (vix)^ lat. % lines. 



The antennaB are shorter, and have joints 6-10 much more 

 evidently compressed and dilated, than those of T. mnea ; com- 

 pared with those of T. antennata they are somewhat longer with 

 less dilated joints. The puncturation of the upper surface dis- 

 tinguishes the present insect from both those just named, being 

 very similar to the puncturation of some of the larger species of 

 the genus, — especially T. Iceta and negligens. My two examples 

 are both females.

Tomyris (?) paradoxa, sp.nov. 



Late ovata; glabra; sat nitida; subtus picea, vix seneo-micans ; 

 supra seneo-cuprea ; labro (hoc exempiis nonnullis infuscato), anten- 

 nis (his apicem versus obscuris), palpis, pedibusque rufo-testaceis ; 

 capite verticali, prothoraci profunde insertum, crebre minus subti- 

 liter (clypeo laevigato excepto) punctulato; oculis magnis minus pro-
