in front, with a few short hairs; two longer hairs (one

 which two are very long, and a few shorter hairs; occi- 

 pital margin concave, straight in the middle ; palpi project- 

 ing slightly; occipital margin narrowly bordered with 

 black; temples clouded; a curving, blackish brown, ocu- 

 lar blotch, and in front of its anterior end a small, blackish 

 brown, submarginal blotch. 



Prothorax short, broad, the lateral angle being but little 

 produced, with two short strong spines and no hair, and 

 the posterior angles very obtuse, hardly apparent; the 

 posterior margins flatly convex, with six short strong 

 hairs; segment without distinct colored blotches or bor- 

 der; the transverse chitin bar slender, inconspicuous. 

 Metathorax with fine but distinct suture, separating meso- 

 thorax; just behind the suture a transverse series of a 

 few very small spines; posterior angles of metathorax 

 with three spines and a hair, two of the spines projecting 

 laterally, the other spine and hair projecting posteriorly; 

 posterior margin straight, with a marginal series of hairs; 

 the posterior angles of the segment are obtuse and pro- 

 ject laterally conspicuously beyond the abdomen. 

 Legs concolorous with body, with ill-defined marginal 

 markings. 



Abdomen short, elliptical, lateral margins projecting 

 but little; posterior angles with two short, strong, distinct 

 spines, and usually with a long hair; a broad transverse 

 brown band entirely across each segment, paler in middle, 

 darker at lateral extremities so as to form broad, dark, 

 lateral bands ; the sutures broad, uncolored ; last segment 

 with uncolored posterior border, flatly convex or almost 

 straight, with a few short hairs, and at each side a long, 

 strong, prominent hair.
