3& ENTOMOLOGICAL NEWS. [Jan., '17 



the head, apical collar present ; eyes distant from the front of 

 the pronotum ; rostrum short, not reaching the front coxae. 

 Embolium narrow, linear ; membrane with only one vein, 

 situated near the inner margin. Mesosternum greatly de- 

 veloped, convex, with a short anterior carina ; metasternal ori- 

 fices long, curved forward, reaching the lateral and anterior 

 borders of the metapleurae. Legs slender, the femora some- 

 what thickened. Body oblong, shining, clothed with sparse 

 hairs. Wing-cell with a hamus. 



This genus belongs to the Anthocorinae and should be 

 placed before Anthocoris which is easily distinguished from it 

 by the much less elongate head and pronotum and the 4-veined 

 membrane. Triphleps contains smaller species with 3-veined 

 membrane. 



Macrotracheliella nigra sp. nov. 



Shining black, third antennal segment narrowly yellow at base, tarsi 

 dark brown, paler beneath. First antennal segment not quite reaching 

 apex of head, second about twice the length of the first, enlarged in 

 apical half, third somewhat longer than the first, fourth missing. Pro- 

 notum impressed just within the slightly knobbed lateral angles, pos- 

 terior lobe convex, very finely punctate, declivous, meeting the im- 

 punctate horizontal anterior lobe in a sharply defined transverse line. 

 Scutellum convex and finely punctate basally, the apical half strongly 

 depressed, flat, transversely rugose, acute at apex. Hemielytra very 

 obscurely punctate, the corium longitudinally convex, the cuneus de- 

 flected and slightly concave ; membrane extending beyond apex of ab- 

 domen, brown, narrowly pale along lateral half of cuneal margin and 

 at the inner basal angle. Clothed above and below with very sparse 

 erect hairs, legs and antennae sparsely pilose, the pubescence of the 

 tibiae finer and close. Length 2.5 mm. 



Holotype 9 , Chilmark, Massachusetts, 14 Aug., 1911 (J. A. 

 Cushman), in the collection of the Boston Society of Natural 

 History. 



Closely related to M. laevis Champ., to judge by the de- 

 scription and figures, but differs from that species in having 

 the third antennal segment pale only at base and the hemiely- 

 tra entirely black while the first and second antennal segments 

 are shorter. (In the type specimen the fourth antennal seg- 

 ments have been broken off) .
