This description is taken from one of Say's original specimens. It has the mandibular 

 tooth very distinct, but the labium is convex, with a straight border, without denticu- 

 lations. The posterior legs are much elongated, and the lateral appendages margined, 

 and terminated with an acute spine. The preanal scale is subcordate, with the posterior 

 border slightly rounded. 



5. Scol. longitarsis (Tab. XL. fig. 10.), aurantiaca, capite mandibulis labio segmentorumque 



margine posteriore rufis, pedibus pubescentibus flavis ; postremis attenuatis valde elon- 

 gatis articulis tarsalibus metatarsalibusque 12 : femore tibia longiore, illo inferne longi- 

 tudinaliter 4-spinoso, h^c bispinosa. — Long. unc. If.

This is an exceedingly interesting species. The cephalic segment is convex, subquadrate, 

 ovate, with a slight sulcus between the insertions of the antennae : the dental border of 

 the labium is nearly straight, with a very slight emargination : mandibles tipped with 

 black: dorsal plates convex, not margined, but impressed on each side with a deep 

 sulcus, and having the posterior angles slightly produced ; posterior pair of legs elon- 

 gated, tapering, fourteen-jointed ; the femur and tibia spined. Lateral anal appendages 

 also much elongated, with the apex black and acute. Preanal scale quadrate, rather 

 narrow behind, with the margin straight.

The genus Cryptops, as defined by Dr. Leach, is a well-established section ; 

 but some species have been included in it which seem not to answer pre- 

 cisely to the characters that have been given. Thus the C. sexspinosa, Say,
