Cryptops heathi, sp. nov. 



Color yellowish. Head a little darker than the body. 



Head widest anteriorly, the sides converging caudad; caudal mar- 

 gin straight, meeting the edge of the first dorsal plate flush or scarcely 

 overlapping the latter. Sulci not evident in middle and anterior 

 portions; but rather faintly indicated caudad. Scarcely punctate. 



Prosternum not punctate; with a median longitudinal furrow. 

 Anterior margin nearly straight, being very slightly bowed caudad 

 toward each end; bearing three bristles on each side. (Plate 1, fig. 2). 



First dorsal plate with a distinct transverse cervical sulcus which 

 is angularly bent caudad at the middle line, the plate being depressed 

 at this angle. Two longitudinal sulci present, but these in the type 

 are rather weak; forking cephalad, the inner branches meeting at an 

 angle at the median line a little caudad of the cervical sulcus and the 

 lateral lines each meeting the sulcus farther laterad (see Plate 1, fig. 1). 



All dorsal plates from the second to twentieth longitudinally bisul- 

 cate. Plates not roughened; none of them bearing cornicles. 



Last plate with a shallow median longitudinal furrow which is more 

 evident toward the caudal end.
