Hoplitis sambuci, n. sp. 



9' Length 8.5 mm. Black, abdomen shining black; stout, head fully 

 as wide as thorax, strongly produced behind the eyes. Punctuation dense 

 and exceedingly regular over the entire insect, including femora and tibiae. 

 Pubescence varying from gray to white. Pubescence dense on face, 

 cheeks, scutellum, and sides of thorax, very sparse on occiput and thoracic 

 disc. Front legs with rather dense pubescence, that on middle and hind 

 legs shorter and sparser. Dorsal abdominal segments 1-5 with snow-white 

 apical hair bands broadly interrupted (rubbed?) in the middle, 6th seg 

 ment with short white pubescence. Ventral scopa dense and white. An 

 tennae black, scape somewhat enlarged, mandibles jet black, grooved 

 externally, with three teeth, the outer one slightly longer and more 

 pointed, the second and third separated by a shallow curve; clypeus 

 truncate ; tibial spurs black, spine at apex of front tibia strongly produced. 

 Labial palpi four jointed, second joint i^ times as long as first, first two 

 joints very slender, third and fourth stout subequal, maxillary palpi five-

 four subequal, five slender, short. 



(j\ Length 8.5 mm. Black, closely resembling female, facial pubes 

 cence whiter and denser, thoracic pubescence cinereous and dense ; abdom 

 inal bands present on segments 1-6, interrupted in the middle, sixth seg 

 ment narrowly ferruginous apically, dentate laterally; seventh segment 

 truncate, broad, curving laterally to its base; sides of abdomen and last

Type. No. 6S6o, U. S. National Museum. 



I have examined the type species of the genus Hoplitis King 

 ( Osmiaadunca L.) and feel sure that this species and Alcidamea 

 truncata Cress, belong therein. It can be readily separated from 

 A. truncata by size, form, and pubescence. The antennae in 

 Hoplitis are quite varied, but the majority of species have de 

 formed antennae. 



Acanthosmiades ashmeadii, n. sp. 



<j\ Length 10 mm. Head and thorax dull blue, abdomen shining 

 steel-blue. Head and thorax disproportionately large lor the abdomen, 

 head as wide as thorax, abdomen slender. Punctuation confluent on head 

 and thorax, dense and fine on abdomen. Pubescence of face, cheeks, 

 occiput, borders of thoracic dorsum, and sides of thorax dull white in some 

 places discolored with vellow, of abdomen very sparse, but where occur 

 ring is short and black; on dorsal segments 3-6 it can be plainly seen 

 from the side, beneath the sides of the abdomen are fringed with black
