ee. The sulcus of average width and depth ; the spines of hoth cari- 

 na' small and sub-equal in size. 



/. General color clear reddish brown, mottled with paler ; each of 

 the carina' of the hind femora with about 28 crowded minute 

 spines.

 Clear reddish-brown, mottled with small pale spots, especially on the 

 abdomen, where the spots have a tendency to arrange themselves in lon- 

 gitudinal rows. The legs paler, the exterior face of the hind femora with 

 the usual darker bars, but not so prominent as in C. mactdatus. Anterior 

 femora a little longer than pronotum, unarmed beneath. Intermediate 

 femora also unarmed or with a single apical spine on front margin. 

 Hind femora of medium thickness, the inferior sulcus of average width, 

 rather deep ; the spines of both carime more like the fine teeth of a saw, 

 about 25 in number and crowded on the apical two-thirds of the segment. 

 Hind tibipe straight, a little shorter than the femora. 



Measurements: Male — Length of body, 18 mm.; of pronotum, 5 mm.; of 

 front femora, 6.5 mm.; of hind femora, 18.5 mm.; of hind tibiae, 16 mm. 

 Female— Length of body, 18.5 mm.; of hind femora, 18 mm.; of ovipositor, 

 9 mm. 



As Brunner has well said it is impossible to distinguish C. lapidicolus from 

 Burmeister's description, which was founded upon two female specimens 

 from South Carolina, and undoubtedly many references to it are wrong. 

 If any person is competent to judge as to what lapidicolus really is, that 

 person is Mr. Scudder, and I have determined the form described above 

 from specimens bearing that name kindly loaned me by him. 



In Indiana, lapidicolus is not a common insect, its range probably being 

 more southern. Several specimens have been taken in Putnam county 

 from beneath logs in damp woods.
