different form from anything- so far described, enough so, indeed, 

 to make it the type of a new genus. 



Female.— Body, length 2.85 mm., width 1.35 mm. With the 

 exception of the central portion of the abdomen, it is uniformly 

 pale brown, with darker reddish-brown markings. Head, length 

 .86 mm., width .90 mm., somewhat shield-shaped, rounded in 

 front with four short hairs on each side ; sides nearly straight ; 

 temples obtusely angled, with two longish hairs ; occipital mar- 

 gin convex, with two stiff hairs on each side ; occiput deeply 

 concave; trabeculae nearly twice the length of the first segment 

 of the antennae, triangular with a darker band along the lateral 

 margin ; antennae short, concolorous with head, first segment 

 longest, second and fifth, and third and fourth equal ; antennal 

 bands extending in a curve from the anterior point of the trabec- 

 ulae to the base of the mandibles ; a narrow, transverse serrated 

 band across the posterior portion of the head ; a dark occipital 

 signature between the occipital margin and the transverse occip- 

 ital band ; occipital bands extending from the base of the pos- 

 terior root of the mandibles to the transverse occipital band ; a 

 narrow transparent lobe extends along the lateral borders of the 

 temples. 



Prothorax short, narrow, with lateral angles produced to a 

 blunt protuberance, furnished with a short stiff spine; with the 

 exception of the posterior median portion it is completely encir- 

 cled by a broad, reddish-brown band. 



Mesothorax broad, lateral portion expanded anteriorly ; lateral 

 angles blunt, furnished with two stout hairs; postero-lateral por- 

 tion slightly concave, with two stout hairs towards the angle; 

 the portion touching the prothorax broadly bordered, while two 

 longitudinal curving bands extend across the segment from the 

 ends of the lateral bands of the prothorax, enclosing a median 

 clear spot ; posterior margin transverse, slightly concave. 



Metathorax scarcely wider than the prothorax, somewhat tri- 

 angular in shape, but completely divided longitudinally by a 

 clear suture ; without hairs and with a broad, dark, slightly 

 curving band extending across the anterior portion and con- 

 tinuous with the lateral bands of the abdomen.
