Cacellus propinqucs, n. sp. 

 9 - Black : legs (including coxae) wholly golden -yellow ; 

 scape dusky-yellow, the pedicel and funicle joints fuscous, the 

 club black. Head no wider than the thorax, from dorsal 

 aspect twice as wide as long : with large, dense, umbilicate 

 punctures, confluent on the vertex; lower two-thirds of face 

 (except laterally) smooth and depressed : vertex descending 

 toward occiput, the latter gently concave ; eyes large, bare ; 

 ocelli large, the lateral pair touching the eye margirs. Thorax 

 one-half longer than greatest width ; pronotum slightly visible 

 on the sides from dorsal aspect ; scutum large, plainly wider 

 than long, the median lobe with dense large punctures, not 

 confluent, the lateral lobes narrow, with fine pin-punctures 

 joined by fine impressed lines; parapsidal furrows deep, 

 complete, foveate ; scutellum semicircular, at posterior margin 

 with a row of deep foveae, its surface with scattered punc- 

 tures, these fine mesally : post-scutellum short, foveate, 

 unarmed : metanotum at base with a rather long semi- 

 horizontal bidentate spine. Abdomen one-half longer than 

 the head and thorax united ; sessile, slightly narrowed at base, 

 gradually tapering to apex ; segments all longer or as long as 

 wide, the second and third slightly the longest; six segments 

 visible, the first strongly striate, second and third longi- 

 tudinally confluently rugose-punctate, the sculpture becoming 

 finer on 4-6, the sixth at apex with a small emarginate plate ; 

 basal segment without a horn or prominence. Legs long and 

 slender. Forewings almost attaining apex of abdomen ; 

 broad : faintly infuscate : venation dark-yellowish : marginal 

 vein a little but distinctly longer than the stigmal, which is 

 moderately long, straight, almost perpendicular, the post- 

 marginal twice as long as the marginal ; basal vein very faint, 

 very oblique, the median represented by a thick fuscous line. 

 Scape slender ; pedicel a little over twice as long as greatest 

 width; first funicle joint much longer, almost twice as long 

 as the second, which is hardly twice as long as wide, the 

 third a little longer than wide, the fourth plainly wider than 

 long ; club compact, 6-jointed, joints 1-5 plainly wider than 

 long, the first distinctly the longest. Length, 4 '20 mm. 



d . Like the female, but the lateral lobes of the scutum 

 with large shallow punctures; punctures on scutellum more 

 numerous and of uniform size ; metanotum longer, without 

 the bidentate spine, this modified to a pair of median carinae ; 

 tarsi darker; abdomen at apex truncate and bispinose. 

 Antennae black, the scape bright-yellow; pedicel one-half 

 longer than wide; first funicle joint nearly twice as long as 

 pedicel, thrice as long as wide, the second distinctly shorter,
