HELCOSTIZUS ANNULICORNIS (Walsh). 



Echthnts annulicornis Walsh, Trans. St. Louis Acad. Sci., vol. 3, 1873, p. 159. 

 This species appears to be a small, slender Helcostisus with two 

 transverse carinae on the propodeum, though the wording regarding 

 the latter character is somewhat obscure. Except for the size and 

 the proportions of the flagellar joints and tergites the type of 

 Helcostizus hicarinatus Cushman agrees very well. 



SPILOCRYPTUS CIMBICIVORUS, new species. 



Very closely related to its European congener of the same host- 

 relations, cimMcis (Tschek), but the basal flagellar joints are rela- 

 tively stouter and in the female the inner orbits immaculate. In the 

 male also it differs in having the front and middle coxae entirely 

 black, the face white only laterally, the malar space immaculate, the 

 frontal orbits not at all or only narrowly white, the pronotum white 

 at most only medially, and the subalar tubercle, scutellum and post- 

 scutellum, and propodeum immaculate, and the white of the hind 

 tarsi confined to joints 2-4. 



In Provancher's key ^ to the species of Gryptus the female runs 

 to nuncins Say and the male to apicatiis Provancher. From nuncius 

 the female differs in the relatively shorter basal flagellar joints, 

 medially wanting apical carina of propodeum and stronger apo- 

 physes, the partly red fourth tergite, and the lack of white on the 

 hind tarsi. From apicatus the male differs in its white inner orbits, 

 clypeus, mandibles, palpi, and tegulae; stouter thorax; medially 

 wanting apical carina; smooth and noncarinate first tergite with its 

 spiracles far beyond the middle; entirely red tergites 2-4; white 

 spotted seventh tergite and white annulate tibiae and tarsi. 



Female. — Length, 7 mm. ; antennae, 5 mm. ; opipositor, 1.5 mm. 



Head shagreened and sparsely punctate; temples strongly convex, 

 receding, almost impunctate; cheeks polished below; frons medially 

 finely, irregularly rugulose: face medially longitudinally elevated, 

 with a shallow impression on each side just above clypeus; clypeus 

 elevated medially and with a narrow reflexed margin; malar space 

 about as long as basal width of mandible; eyes parallel; basal joints 

 of flagellum elongate, first slightly longer than second. Thorax 

 rather stout; pronotum longitudinally rugulose laterally behind the 

 distinct epomia, mesoscutum polished, with fine separated punctures, 

 notauli fine but distinct ; scutellum like mesoscutum but more sparsely 

 punctured; mesopleurum finely rugulose punctate, sternum punc-
