1916] Girault — New EncyrtidcB from North America 47 



Oblique hairless line rather broad with but several lines of cilia 

 proximad of it. Abdomen no longer than the thorax, the ovipositor 

 tipping it. 



From six females "Hopk. U. S. 10958 c, July 27, 1914. On 

 Nyctohates pennsylvanica, Shiremantown, Penn. Hicoria. W. S. 

 Fisher." Type: Catalogue No. 19316 U. S. N. M., a female on a 

 tag; five female paratypes. 



Ceraptroceroideus Gen. nov. (Encyrtini), 



Female: In my table of genera runs to Ceraptrocerus Westwood 

 but wingless, the head is not oblong but subquadrate (cephaUc 

 aspect) and the second segment of the abdomen occupies nearly 

 half of the surface, the sixth next largest, two-thirds the length 

 of the second. Pronotum extremely short. Scutum wider than 

 long but as long or nearly as the normal scutellum whose rounded 

 apex reaches to the base of the abdomen. Axillae separated for 

 some distance. Vertex flat, the face inflexed, the frons prominent. 

 Vertex of moderate width. Mandibles with the inner two teeth 

 formed by a concaved broad second inner tooth whose lateral or 

 dorsal apex is acute. Fore wings mere scales which are somewhat 

 longer than wide, with a broad costal cell and distinct submarginal 

 and marginal veins, the latter much shorter than the former. 

 Middle tibial spur long and stout, the caudal spur single, slender. 

 Ovipositor slightly extruded, pointing the abdomen. Type: C. 

 cinctipes, sp. nov. 



Ceraptroceroideus cinctipes sp. nov. 



Female: Length, 1.10 mm. Purplish black, the scutellum except 

 lateral and caudal margins narrowly and the rest of the dorsal 

 thorax, except the tegulse and much of the surface of the scutum, 

 reddish brown. Head purplish black, the vertex bright lemon 

 yellow, except the lateral margins unnarrowly along the eyes and 

 the cephalic margin broadly. Face with a broadly curved, narrow 

 lemon yellow stripe across it just under the vertex far dorsad of the 

 antennae, its (lateral) ends terminating under the eye ends. Lateral 

 ocellus in the mesal margin of the lateral black border of the vertex, 

 over its diameter from the eyes. Head finely scaly. Eyes partly 

 on the vertex, the cheeks longer than them. Cephalic legs purple 

 except tips of the tibiae broadly and the four proximal tarsal joints.
