Head subovate, hind angles strongly rounded; with irregularly distributed 

 and fairly large sharply-defined punctures, absent from a small median space. 

 Mandibles rather long and strongly dentate. Antennae thin, passing base of 

 prothorax, first joint as long as second and third combined, fourth slightly longer 

 than second, and distinctly shorter than third and fifth, the others to tenth 

 gradually decreasing in length, but all distinctly longer than wide. Prothorax 

 distinctly longer than wide, all angles rounded, apex slightly wider than base, 

 sides with a very feeble incurvature near base ; punctures sharply defined but 

 smaller than on head, not very dense, and absent along middle. Elytra about 

 one-fourth wider than prothorax, and slightly longer ; each with five somewhat 

 irregular rows of moderate punctures on disc, becoming irregular posteriorly, 

 a few on sides. Abdomen with punctures (both surfaces) smaller, denser, 

 and more asperate than on apical parts of elytra. Front femora rather stout and 

 moderately dentate ; front tibiae notched near basal third ; front tarsi with four 

 basal joints slightly wider than apex of tibiae, the other tarsi longer and thinner, 

 with the basal joint as long as the three following combined. Length (excluding 

 mandibles), 9 mm.

In general appearance somewhat like 5". laetum and 5*. arcuatum, but with 

 darker elytra and paler prothorax, the punctures are also much sparser on the 

 prothorax and elytra. The elytra are smaller than is usual on winged species of 

 the genus, but I have made sure that wings are present. I have not dissected 

 out the mentum of the type, but it has two globular appendages at the apex, 

 apparently as in species of Hyperomma. On the type the abdomen is unduly 

 extended, with the membranous parts of five segments showing conspicuously 

 pale. The head and prothorax are highly polished, the elytra rather less so. 

 The punctures on each side of the median line of the prothorax are irregularly 

 lineate in arrangement.

6 ■ Bright castaneous-red ; two apical segments of abdomen, femora, and 

 tibiae black, four to six basal joints of antennae infuscated or black, the others 

 pale. Upper-surface moderately clothed with ashen pubescence, the head and 

 prothorax more sparsely than elsewhere. 



Head, excluding mandibles and neck, distinctly transverse ; with fairly large 

 and numerous but not crowded punctures, and with minute ones scattered about. 

 Antennae extending to base of prothorax, first joint curved, as long as second and 

 third combined, third almost twice as long as second and fourth, seventh to tenth 

 subglobular, becoming feebly transverse. Mandibles stout and strongly dentate. 

 Prothorax at apex almost as wide as the median length, but base narrower, all 

 angles moderately rounded off; punctures much as on head, but absent from a 

 rather narrow median line. Elytra slightly wider than widest part of prothorax 

 and not much longer, angles rounded off, sides almost parallel; with rather 

 dense and sharply-defined punctures, slightly larger and denser than on pro- 

 thorax and head. Abdomen with numerous asperate punctures ; under-surf ace 

 of sixth segment with a deep narrow notch. Legs not very long, front femora 

 stout and obtusely dentate, front tibiae notched at about basal third, four basal 

 joints of front tarsi dilated to form an ovate pad, basal joint of hind tarsi almost 

 as long as three following combined. Length, 8.5-10.5 mm. 



$ . Differs in having slightly shorter antennae and legs and abdomen not 

 notched.
