obliterated ; (?) broader, the sides sinuate just bej^ond the middle. 

 Elytra broader than the pro thorax, comparatively short, sub- 

 parallel in cj, slightly explanate from a little below the shoulder in $, 

 roughly punctate. Inner claw of anterior tarsi and outer claw of 

 intermediate tarsi with an angular lobe at base in c^. 



(^. Ventral segment 6 feebly emarginate in the middle behind, 

 7 cleft and comparatively short, 9 short, broadly produced in the 

 centre at the apex, a stout hook visible on either side of it. 



Length (excl. head) 6-7|, breadth 2tV-3 mm. {^ $.) 



Hab. Mexico, Ciudad in Durango (Edge). 



One pair. A comparatively short, broad form, with 

 the prothorax rounded at the sides behind, the lateral 

 notch in the male deep, the outer posterior tarsal claw 

 almost simple in this sex. In the unique male (after the 

 genitalia have been extracted) an extremely long, slender, 

 curved rod is visible in the fissure of the seventh ventral 

 segment, arising from beneath the apical margin of the 

 sixth, its apex being a little thickened and set with several 

 setae. The prothorax of the (^ is notched as in P. hinotatus. 

 Fall, but it is more transverse, and more rounded at the 

 sides posteriorly. 



17. Polemius bimaculatus, n. sp. 



$. Comparatively short and broad, shining, cinereo-pubescent ; 

 black, the anterior portion of the head, joints 1-3 of the antennae 

 and the base of each of the following joints, the prothorax (two oblong 

 streaks on the disc excepted) and scutellum, the sutural and outer 

 margins of the elytra, the coxae and trochanters, the anterior 

 femora and tibiae, and the bases or more of the other femora and 

 tibiae, and the abdomen in part, flavous or testaceous. Head 

 broad; eyes small; antennae rather short, slender. Prothorax 

 strongly transverse, the sides scarcely reflexed, rounded anteriorly, 

 and constricted just before the base, the hind angles obtuse. Elytra 

 comparatively short, a little wider than the prothorax, feebly widened 

 from below the shoulders, roughly punctate. Legs rather stout. 



Length (excl. head) 6-6 J, breadth 21-2 J mm. 



Hah. Mexico, Chilpancingo in Guerrero {H. H. S?nith : 

 type), Ventanas in Durango (Hoge). 



Two females, the one from Durango somewhat immature 

 and with the antennae entirely testaceous. This species 

 comes near P. breviusciihis , but the shape of the prothorax 

 ($) is so different in the two forms that it is impossible to
