inward before it reaches the antennae and bearing a row of fifteen 

 long, flattened, blunt spines. On the dorsal surface of the hind head 

 are two rows of five sharp spines each, extending obliquely inward 

 and backward. Just forward of the first spines of this series are two 

 more. Occipital margin sinuous and bordered by thirty-four of the 

 characteristic flat spines. On the posterior lateral angles are three or 

 four sharp spines. Antennae, length, .26 mm., four jointed; basal seg- 

 ment broad, flat, triangular shaped with the apex pointing forward 

 with a row of the broad, flat spines across the base on the ventral sur- 

 face ; second segment long, cylindrical ; third and fourth short, the dis- 

 tal segment a trifle the longer ; numerous spines on all the segments. 



Thorax over twice as long as the head, 1.08 mm. Prothorax, length 

 .56 mm., width, .6 mm. The general shape is quadrilateral, the widest 

 part a little posterior of the middle; sides flatly rounded, meeting the 

 slightly convex anterior margin in an obtuse angle ; a row of short 

 spines occurs paralleling the median portion of the anterior margin ; 

 behind these are three long spines on each side which point toward the 

 meson ; entire surface of prothorax covered with short, sharp spines, 

 with the exception of a bare central area. The posterior margin is 

 convex and meets the sides in an angle ; along this margin is a row or 

 thirty-seven broad, flat spines. Mesothorax broader than long; length 

 .46 mm., width .58 mm. ; anterior margin convex, extending under the 

 prothorax ; anterior angles broadly rounded, the segment here present- 

 ing the greatest width ; lateral margins flattened and narrowing to 

 meet the posterior margin in an angle ; posterior margin convex, bear- 

 ing a row of thirty-four broad, flat spines. This segment is divided 

 along the meson from the posterior margin nearly to the middle; en- 

 tire surface covered with short spines, with the exception of a bare 

 central area. The metathorax has the appearance of being the first 

 abdominal segment and extends under the mesothorax to the anterior 

 end of the median division of that segment. At the anterior lateral 

 angles is a chitinous process and a dark blotch, seen through the meso- 

 thorax. 



Prothoracic legs short and carried folded under the prothorax ; 

 tibiae almost as broad as long; tarsi three segmented. Meso- and meta- 

 thoracic legs long, tibiae slender; posterior pair extending beyond the 

 end of the abdomen ; tarsi four segmented with two claws, one of 

 which is heavy, compound and recurved ; simple claw smaller. All the 

 legs bear numerous spines. 



Abdomen elliptical; eight segmented; a row of short spines ex- 

 tends across each of the first seven segments and numerous spines are 

 near the lateral margin of each segment.
