Clinocephalus gen. nov. 



This genus occupies an intennetliate 

 position between Dicliroiitorplia and 

 Orphiila and is closely related to the 

 tbrmer from which it differs especially 

 in having the sides of the pronotuni 

 convex below the lateral carinae, whicli, 

 in addition, are slightly divergent on 

 the metazona. The type species, 

 described below, has been referred to 

 Stenobothriis occidentaUs Sauss. by 

 Prof. Bruner, but it does not agree 

 with the description of that species in 

 some important particulars and is 

 probably new, an opinion concurred 

 in by Prof. McNeill to whom I have 

 sent an example.

Antennae filiform, slender, in f, longer 

 than head plus pronotum, in % equal to 

 head pins prozona. E^'es large, of $ twice, 

 of 5 one and a half times the length of the 

 snb-ocular sviture, and two-tliirds as wide as 

 long. Vertex in side view nearly horizontal ; 

 seen from above as wide ( <J ) or wider (?) 

 between the eyes as the greatest width of an 

 eye; the anterior inargin distinctly elevated, 

 in the $ right-angled or slightly acute and 

 rather sharp at the apex, in $ more blunt 

 and rounded ; projecting in front of the eyes 

 but little less than the width of an eye. 

 Foveolae absent but the 9 shows a row of 



small punctures on llie front of the anterior 

 margin. The top of tlie head shows a slight 

 elongate medial depression in the conve.x 

 part of the fastigiuin opposite the anterior 

 end of the eyes, and also a pair of very 

 shallow arcuate grooves, concave laterally, 

 running from the end of the elevated margin 

 of the vertex opposite the anterior part of 

 the e3'es back to the front margin of the 

 pronotum, striking it about two-thirds of 

 the way from the median to the lateral cari- 

 nae. Face strongly retreating; costa rather 

 deeply sulcate, in profile slightly curved {$) 

 or nearly straight ( ^ ) slightly rounded above 

 to meet vertex. 



Pronotum elongate, longer than the ante- 

 rior femora ; the disk twice (?) or twice and 

 a half (J ) as long as wide. Carinae distinct, 

 equally developed, the lateral parallel on the 

 prozona, slightly divergent on the metazona.- 

 Metazona on midline two-thirds (({) or 

 three-fourths ( $ ) as long as prozona. Hind 

 margin very obtusely angulate or nearly 

 truncate. Sides of the pronotum with the 

 dorsal third convex, the ventral two-thirds 

 vertical, very similar in outline to D. viridis 

 (Fig. 7b), longer than high, the front and 

 hind margins of nearly equal length, con - 

 verging downward, the hind margin becom- 

 ing nearly vertical in its ventral fourth; 

 lower margin obtuse-angulate just behind 

 its middle, the tw-o portions straight and 

 nearly equiangulate with the lateral carina 

 in direction. 



Tegmina nearly or quite reaching the tip 

 of the abdomen, extending one-half to two- 

 thirds down the hind femora, the marginal 

 area dilated, tapering from that to tip; (J 

 with the ulnar area enlarged, coarsely, — 

 even scalariform-reticulated, except at base; 

 5 similar but less enlarged, and less regu- 

 larl v reticulate.
