"Type. — Antennas about half the length of the body ; the 

 three terminal segments usually sub-equal, but the second may 

 be either a little longer or a little shorter than the other two. 

 Color yellow, shading off to violet in the lighter specimens, to 

 brown in the darker ones ; there is sometimes a brown ring 

 at the tip of the first segment. Head yellow, with a broad dark 

 band around the margin as seen from above crossing the eye 

 patches. The anchor-shaped band on the crown of the head 

 is usually well defined. 



"Mesothorax slightly longer than metathorax, with a dark 

 band on its anterior margin which runs along the epimera as 

 far as the fourth abdominal segment; there is also a strong 

 central basal band not reaching the margin ; there is a similar 

 basal band on the metathorax. The first three abdominal seg- 

 ments increasing in length wuth similar dark basal bands on 

 each ; that on the first shows a little thickening at the extrem- 

 ities; those on the second and third have this thickening in- 

 creased to a triangular patch. Fourth abdominal segment not 

 so long as the first three and the metathorax taken together, 

 fusiform, with 1^o interrupted bands, one across the center and 

 one across the basal portion of the segment, sometimes the two 

 bands unite by triangular patches on each side of the median 

 line ; this segment is narrower at the base than the mesotho- 

 rax. Fifth and sixth abdominal segments small, with strong 

 basal bands. 



"Spring not passing the ventral tube. Claws strong; the 

 upper one with a tooth about the center of the inner margin, 

 but there is often another smaller one, and sometimes a very 

 small one on the outer margin. Lower claw lanceolate. Lateral 

 plates lanceolate and a little curved; sometimes the tip of one of 

 these plates is in such a position as to be easily mistaken for a 

 strong tooth on the upper claw. 



"Length, 1/15 inch; width, 1/50-1/60 inch."
