"Type. Antennae 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 with 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 two 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."
