This species is very closely related to the genotype, photoinovphus 

 Viereck, but can be immediately distinguished by the confluence of 

 the black markings of the frons and occiput with the resulting disap- 

 pearance of the conspicuous, transverse, yellow stripe behind the 

 ocelli. In the present species, this black marking reaches the eyes, 

 which it does not do in photomorphus. The second tergite is less 

 distinctly reddish at base and has a distinct, black band across the 

 middle, while the black of the third tergite is more distinctly re- 

 moved from the base than in photomorphus. In the male, the ab- 

 domen is usually without black markings, but one specimen has them. 

 The genotype appears to be no more than a variety of pachymenae. 



Gryptamura is known to me only from BruUe's description, but 

 pachymenae certainly does not belong there if only for its large 

 anteriorly convergent areolet, this cell in Cryptanura being small 

 and parallel sided as in Pohjcyrtus. 



PHOTOCRYPTUS ATER. new species 



Very distinct from the other two species referred to the genus by 

 its largely black color, 



T^'ewa^e.— ^Length, 8 mm.; antennae, 7 mm.; ovipositor sheath, 

 4 mm. Eyes very large, in front view each occupying more than 

 one-third the width of the head; face very slightly narrower than 

 frons; face and clypeus minutely shagreened and sparsely, weakly 

 punctate; clypeus slightly more than twice as broad as long; malar 

 space nearly obliterated; pronotum smooth and polished laterally, 

 with strong rugosities in the lower angle; mesoscutum coarsely, 

 closely punctate, scutellum sparsely so; pleura more sparsely and 

 more finely punctate, polished; propodeum punctate before basal 

 carina, coarsely, transversely rugose behind; inner hind calcarium 

 nearly twice as long as outer and nearly three-fourths as long as 

 basitarsus; abdomen slender; first tergite with postpetiole very little 

 broader than petiole; second nearly four times as long as broad at 

 base. 



Black with the following white markings: Face, clypeus, mouth 

 parts, cheeks, orbits, except at top of eyes behind, scape and pedicel, 

 propleura, pronotum anteriorly, tegulae, subalar tubercle, median 

 spot on mesoscutum, scutellum transversely at base, upper division of 

 metapleurum and a spot at apex of lower division, a median spot 

 and two lateral apical spots on propodeum, front and middle legs 

 (except a black streak on posterior face of femora, the middle tarsi, 

 and the apical joint of front tarsus), spot on upper face of hind 

 coxae, proximal joint of hind trochanter largely, base of tibia, sec- 

 ond to fourth joints of hind tarsus with more or less of first and 

 i^fth, first and second tergites basally and apically and others nar-
