Hylaeus maritimus n. sp. 



$ Black, elongate spot on tlic sides of the face obliquely truncate 

 to the eye margin at the level of the middle of the antennal socket, 

 interrupted band on collar not greatly narrowed within, tubercles, 

 spot on the subhyaline tegulae, spots on the outer base of front and mid- 

 dle tibiae, basal third of hind tibiae (band prolonged outwardly) yellow. 

 Flagellum pale brown beneath ; margins of tergites and sternites testa- 

 ceous, subhyaline. Wings brownish subhyaline, venation brownish 



Pubescence of head scattered, collar feebly pubescent on its posterior 

 side, plumose pubescence well developed on the posterior angles of the 

 propodeum. Interrupted whitish hair band on posterior margin of first ter- 

 gite and a thinner and less definite one on second, surface of second and 

 following tergites with fine scattered declinate hairs and some longer and 

 more erect ones. 



Supraclypeal area and ch'peus longitudinally lineolate. obliquely punc- 

 tured with piligerous punctures, those of the apical half of the clypeus 

 distant from one to two times the diameter of a puncture, lineolations 

 of the sides of the face obliquely longitudinal, directed to the clypeus, 

 front longitudinally aciculate-punctate, vertex more definitely and dis- 

 cretely punctured, occiput transversely lineolate or minutely rugulose. 

 Mesonotum opaque closely and shallowly punctured, the punctures not 

 separated by one-half the diameter of a puncture : mesopleura more 

 shining, more finely and sparsely punctate, contrasting with the opaque 

 longitudinally rugulose metapleura ; scutellum similar to the mesonotum ; 

 metanotum more opaque with very sliallow almost contiguous punctures; 

 propodeum with the area only fairly well defined, rather coarsely (mi- 

 croscopically) tessellate with a few rugae or reticulations at the base 

 these variable but not much developed, sides and posterior face of 

 propodeum shagreened, posterior face angulate at the sides, not carinate, 

 the basolateral areas not defined. 



Tergite one microscopically sparsely punctate, the surface smooth 

 and a little shining, microscopically transversely lineolate, remaining 

 tergites similar but less shining from the pubescence, tergites not per- 

 ceptibly contracted ; sternites similar but with minute punctures. 



Head greatly developed longer than broad, inner orbits sinuate, feebly 

 converging below, supraclypeal area but little elevated in the middle 

 and gradually descending to the plane of the front, margir.s angled be- 

 tween the antennae, the furrow continued feebly to the anterior ocellus, 

 ■temples broader than the eyes as seen from above, collar with rounded 

 margin a little narrowed medially. Recurrent nervures received by tlie 

 second cubital cell or tlie second interstitial. 



Length about 6.5 nmi. ; wing 5 m.m 



(5 Similar to the female, triangular spot at apex of scape, clypeus, 

 supraclypeal area, sides of face with a clavate extension extending from 

 tlie lower edge of the antennal socket to above its upper edge ; stripe 

 on front ti1)iae. apical as well as basal spot on middle tibiae, and basi-
