9. — Ancistromma consimilis n. sp. 



9 . — Anterior margin of clypeus rounded-out, armed with one 

 tooth laterally ; front closely punctured, medially the punctures are 

 more distinct, but not sparse ; vertex finely and closely punctured ; 

 space between the eyes at top about equal to the length of antenual 

 joints 2-4 united ; antennae much shorter than the head and thorax 

 united, the first and second joints of the flagellum about equal in 

 length ; dorsulum compactly punctured ; scutellum likewise, im- 

 pressed; metathorax above indistinctly transversely striated, not 

 strongly furrowed, the striations most distinct in the furrow, the 

 metapleune finely granulated, or indistinctly striated ; legs strongly 

 spinose ; the spines or fore-tarsi longer and stouter than in divisa ; 

 pygidial area large, strongly and sparsely punctured, only about one- 

 third longer than its width at the base. Black ; abdomen entirely 

 red ; apical joints of tarsi testaceous ; wings dark fuscous, iridescent; 

 marginal cell obliquely truncate ; head and thorax destitute of 

 pubescence or pile. Length 14 mm. 



$. — Anterior margin of clypeus rounded-out, not emarginate 

 laterally ; space between eyes at top about equal to or slightly 

 greater than, joints 2-4 of antenna; united ; antenna? not reaching 

 much beyond teguhe, rather stout, the first joint of flagellum about 

 one-quarter shorter than the second ; dorsulum with the punctures 

 compact; scutellum impressed; legs feebly spinose ; basal segments 

 of abdomen above not distinctly punctured, the last dorsal segment 

 distinctly keeled laterally ; first three segments of abdomen red ; head 

 and thorax without silvery pubescence ; abdomen with a sericeous 

 pile. Length 10-13 mm. 



Texas. This species and divisa resemble each other wonderfully, 

 and at a first glance one would suppose that they are the same spe- 

 cies; but the short antenme and large pygidial area of the female, 

 and the male with the basal abdominal segments impunctate and 

 with the last dorsal segment keeled, will easily distinguish it. 



10.— Ancistromma rugosa n. sp. 



$ . — Anterior margin of clypeus rounded- out, not dentate ; front 

 closely punctured, rather sparsely so medially; vertex with the 

 punctures coarser and more separated than those on the front ; space 

 between the eyes at top as great or perhaps slightly greater than the 

 length of anteunal joints 2-4 united: antenme fully as long as head
