22. CONOCEPHALUS PUSTULATUS Redtenbacher. 



One female. December. 



XIPHELIMUM, new genus. 



3Iale. — Robust. Fastigium narrow, narrower than the basal seg- 

 ment of the antenna?, which it does not surpass, dorsalh^ very narrowly 

 sulcate, separated from the face below by a constriction and trans- 

 verse sulcus; face smooth. Pronotum smooth, subtruncate before 

 and behind, the disk posteriorly considerabl}' elevated and moderately 

 produced; lateral lobes rectangulate below, the posterior border 

 nearly straight, humeral sinus slight, anterior border perpendicular 

 in upper half, the lower half tapering backward, meeting the pos- 

 terior margin at right angles; lateral carina^ barely indicated by 

 broadly rounded angles; prosternum bispinose: meso-and metasternal 

 lobes acute angulate but not spinose. Wings and elytra of equal 

 length, surpassing the short abdomen, but scarcely passing beyond the 

 middle of the long hind femora; elytra very broad, inclosing the 

 abdomen and broadly rounded or subtruncate apicall3% the costal area 

 very broad, transparent and occupied by very distinct parallel trans- 

 verse veins; stridulating organ well developed. Legs slender, anterior 

 and intermediate tibia? with 6 subequal spines on each side below, 

 the posterior tibia^ with an apical spine on each side above; anterior 

 and intermediate femora unarmed, the posterior ones armed below on 

 both margins; genicular lobes spinose. Cerci cylindrical, slightl}^ 

 incurved and armed on the inner side beyond the middle with a broad 

 double-pointed tooth, 



Ti/pe. — Xiphelimum amplipenne, new species. 



This genus is allied to both Xlphidlion and Orchellmum^ the more 

 heavy form giving it more the appearance of the latter. The verv 

 broad elytra with the transparent costal field with its array of distinct 

 parallel transverse veins gives it a ver}^ characteristic appearance. 



23. XIPHELIMUM AMPLIPENNIS, new species. 



Male (female unkno\tn). — General color greenish, the top of the 

 head and of the pronotum anterior of the fairly distinct principal 

 sulcus with a broad mesial band of solid black, rarely extending faintly 

 back upon the posterior part of the disk. Eh'tra with the apex 

 externally longitudinally folded, giving the tip a notched or truncate 

 appearance when view^ed from the side or end. Legs reddish, the 

 apices of the posterior tibiae and femora piceous and the posterior tarsi 

 also black. The posterior legs are very long and the femora are 

 armed on each side below with 5 or 6 stout spines.
