the process bearing two spines; not spined on coxopleural margin 
laterad of the process proper. Porose area not fully reaching the 
caudal margin. (Plate 2, fig. 9). 
Anal legs with articles proximad of the tarsus much thickened, 
especially from side to side as usual. Prefemur and especially the 
femur deeply longitudinally furrowed dorsally at distal ends. Pre- 
femur with a distinct spine at mesodistal angle on dorsal side; two 
small spines near upper edge of mesal surface and three more ventral, 
two being at the distal end ventrad of the corner spine and one toward 
the proximal end; in addition there are four strictly ventral spines, 
two in each of two rows. Femur wholly unarmed. 
Length cir. 43 mm.

One specimen. 
CUPIPES NEGLECTUS, sp. nov. 
Dorsum brown. Head olivaceous. Antennae bluish green. Legs 
pale. 
Head equal in length and breadth. Sulci distinct, diverging cepha- 
lad and each reaching the margin at the eye. Punctae scattered. 
Antennae composed of seventeen articles. In the type the antennae 
are considerably rubbed; but apparently the first article is wholly 
glabrous and the second one nearly so, the third and fourth with an 
intermediate number of hairs and the fifth and subsequent ones with 
the full complement. 
Prosternum with two longitudinal submedian sulci which meet at 
an angle anteriorly; not crossed by any distinct transverse lines. 
Dental plates bearing 4+-4 teeth which are of normal form and long 
and acute; the two intermediate teeth on each side longest; the most 
ectal tooth situated distinctly more proximad (Plate 8, fig. 7). 
Dorsal plates margined from the eighth or ninth segment caudad, — 
the margination becoming more and more distinct in going toward 
the caudal end. Sulci continuous and very distinct on all the plates 
excepting the last. First to third plates with a median longitudinal 
furrow; the fourth plane; those from the fifth caudad with a low me- 
dian longitudinal keel which is flat and set off by two shallow furrows 
in the usual way. Last dorsal plate with a sharply impressed median 
longitudinal sulcus. 1 
Ventral plates from the second to the twentieth distinctly bisulcate. 
Some of the plates showing an indistinct median depression on caudal
