HY ROWLAND E. TURNER. 24:1 



The labrum is almost semicircular, truncate posteriorly, and borne 

 on a short petiole. The labial palpi are four-jointed, the maxillary 

 six-jointed, the joints not diifering much in length. The hypo- 

 pygium has no lateral spines at the base. 



9. The female has the maxillary palpi small, but six-jointed, 

 the labial palpi four-jointed, also small. The mandibles are 

 simple; the head is small, slightly convex. The median segment 

 is short, obliquely ti'uncate; the second abdominal segment is 

 transv^ersely carinated or striated, the number of the carinas being 

 about seven. The pygidium is broad, obliquely or vertically 

 truncate and longitudinal!}' striated. 



The males and females in this group present most unexpected 

 differences, the females closely resembling in appearance those of 

 IVi Ij lino ides, and only showing a likeness to Rhagigaster in the 

 structure of the palpi, though the males have always been placed 

 in that genus without hesitation by previous authors; but 

 Saussure places E. niorio in a division of the genus by itself.
