Hoplitella penlamera, n. sp. 



(J. — Lcngili about 7'.. mm.; licad, thorax and legs black : abdomen 

 with the first three segments bright ferruginous-red, the second and third 

 witli a blackish stain in the middle ; sides of fourth red, the others black \ 

 ventral segments with more or less evident white hind margins ; face 

 densely covered with long silky while hair, stained with yellowish about 

 the middle ; eyes sage-green ; flag;:llum slender, entirely black ; mandibles 

 black ; ocelli large ; thorax with rather long dullish white hair ; area of 

 melalhorax smooth and shining ; teguhv bright apricot colour ; abdomen 

 finely punctured, wiih poorly-developed white hair bands ; spurs creamy- 

 white. 



Hab. — Claremoiit, California. (C F. Baker, 7224.) 



Hoplitella shows many points of resemblance to Proteriades Titus 

 (P. semirubra Ckll.), but is at once distinguished by the 5-jointed 

 maxillary palpi, and the form of the labial palpi, and more superficially by 

 the dusky wings. 



Compared with Chelostoma ( Cep/ialapis) jacintanttm Ckll., it is 

 easily known by the ordinary-sized head, bidentate mandibles, more 

 slender marginal cell, merely emarginate seventh segment, etc. 



Compared with Osmia andrenoides Spinola, from Algeciras ( .\ for ice), 

 it is superficially very similar, though smaller ; but andrenoides has a much 

 longer tongue, the venation is different in several ways (thus, the first r. n. 

 enters second s. m. a long way from base), the sixth abdominal segment 

 has no lateral teeth, and the seventh is bidentate with a pair of triangular 

 teeth. 



Osmia semirubra Friese, from Jericho ( Aforice), also differs greatly 

 in venation from Ifoplitella. The b. n. in semirubra goes basad of the 

 t. m., and the first r. n. enters the second s. m. far from its base. 



Osmia remotula, n. sp. 

 9. — Length about 6'.. mm.; broad, robust; head, thorax and legs

 on inner side of tarsi ; head broad, eyes sage green ; antenn:i' short, 

 entirely bl.ick ; luarulibles black ; head and thorax minutely punctured ; 

 area of melalhorax shining, dull and rugose at base ; teguhv shining 

 piceous ; wings dusky, nervures l)lack ; venation as in O. andrenoides ; 

 spurs creamy white ; abdomen with the first three segments bright 

 ferruginous-red, without bands, exactly as in O. andrenoides, except that 

 ihey arc more feebly sculptured ; oihcr segments black, with grayish-white
