NORTH AMERICAN HYMENOPTERA. 181 



Franconia, New Hampshire (Mrs. Slosson). The markincrs are 

 much paler in this species than in the others of the group, and the 

 head, particuLarly in the female, is more transverse. From what 

 Packard states regarding the variability of the specimens of his 

 maeaHpennw, it seems to me that he had confused more than one 

 species.

 9 ■ — Clypeus of the usual form in this section ; head finely and closely punc- 

 tured, more finely on the cheeks, posterior lateral angles rounded, not prominent ; 

 hind ocelli placed in shallow depressions, which are not so distinct as in nitidi- 

 ventris, and the impi-essed line running from frontal depression to fore ocellus is 

 not quite so deep as in that species ; pronotum less rounded at the sides than in 

 the species above mentioned, and is shorter ; dorsulum closely punctured like the 

 vertex, scutellum a little more sparsely so ; episternal suture of mesopleurse dis- 

 tinctly foveolate: enclosure of middle segment with a broad, transverse, heavily 

 foveolated furrow at base, the central longitudinal channel broadened basally and 

 longitudinally ridged (or as Packard puts it, "the furrow widens toward the base 

 of tlie enclosure so as to include two of the fossae"), the furrow bounding the en- 

 closure outwardly also foveolate, but not so strongly so as the basal furrow, poste- 

 rior face of middle segment not rugose apically, except, perhaps, the extreme 

 apex, the lateral ridges extending up somewhat above the middle, the outer fur- 

 row distinct, but not foveolate ; abdomen finely and closely punctured above, 

 sparsely so on first segment; pygidium somewhat more coarsely punctured. 

 Black, including the mandibles, episternum mesopleuralis and convexities of 

 enclosure of middle segment; two spots on clypeus, sometimes absent, scape, line 

 on pronotum sometimes interrupted medially, tubercles, line on scutellum ante- 

 riorly, spot oy tegulfe, apex of fore and medial femora, tibise, except a spot on 

 inner side of anterior and middle pairs and apex of hind pair, first joint of all 

 the tarsi, a^ traiisversely elongated spot on each side of dorsal abdominal segments 

 2-4 and a band on segment 5, yellow ; sometimes the first segment has two small 

 spots on first segment ; sixth segment has two spots, which are, however, usually 

 concealed through retraction of the segment; apical joints of tarsi brownish, 

 those of the anterior pair palest ; clypeus, inner orbits beneath and cheeks with 

 silvery pubescence; head and thorax with a sparse, pale fuscous pubescence, 

 longest above ; wings subhyaline, with a faint yellowish tinge basally, nervures 

 yellow testaceous, stigma black, the spot in marginal cell scarcely evident. 

 Length 9-10 mm. 



% . — Mandibles except base and apex, pedicellum and joints 1 and 2 of flagellum 

 beneath yellow, a spot on each side of the meso.sternum anteriorly and on each 

 side of third ventral segment of abdomen also yellow (sometimes the mandibles 

 are black and the spots on mesosternum and ventral .surface of abdomen are 

 wanting) ; scutellum either entirely black or with a yellow stripe, or two dots of 

 that color; yellow on i)ronotum sometimes wanting; fore femora entirely yellow
