Sychnoporthus tuckeri, n. sp. 



Female. — Length, 4 mm. Head dullish, minutely sculptured; malar space 

 high, as high as the scape is broad; antenn;t> twenty-five jointed, the scape and 

 pedicellum together about as long as the fourth joint of the flagellum. Thorax 

 dullish ; dorsulum nearly like the face; parapsidal grooves rather distinct on the 

 anterior third of the dorsulum ; mesopleura finely coriaceous, the upper posterior 

 angle smooth and polished, a small pit in the middle of the sclerite at the pos- 

 terior border; metanotum coriaceous with a large pentangular areola which has 

 the sides of equal length or nearly, basal area wanting, petiolarea occupying 

 nearly all of the posterior face of the metathorax, a strong ridge bounding the 

 posterior face of the metathorax, produced into a rather sharp angle above the 

 middle on each side ; metapleura distinctly separated from the metanotum and 

 coriaceous; wings very faintly brownish, nearly clear, stigma and nervures dark 

 brown, the nervures not as dark as the stigma ; areolet if complete would be pent- 

 angular, open behind, sides almost equal; transverse median nervure nearly 

 interstitial, received by the median nervure a little beyond a basal nervure ; trans- 

 verse median nervure in the posterior wings broken about one-third the length of 

 the transverse median nervure above its base. Abdomen nearly smooth ; first, 

 second and third segments coriaceous, except the apical margin, which is pol- 

 ished ; the segments beyond the third entirely polished ; ovipositor exserted about 

 as long as the first two abdominal segments together. Black : scape and pos- 

 terior cox;\3 brownish testaceous, the anterior and middle coxa^ testaceous and 

 whitish, the trochanters of the four anterior legs white or whitish, of the pos- 

 terior legs testaceous, rest of the lege nearly entirely testaceous and somewhat 

 brownish, posterior tibia? especially brownish at base and apex, yellowish be-

Giypta succineipennis, n. sp. 



Closely related to varipes, from which it differs in sulpture, size, and color. 



Female. — Length, 10 mm. Head shining; front closely punctured, the 

 punctures confluent, giving a transverse rugose appearance; cheeks polished, 

 sparsely punctured; clypeus indistinctly punctured; antenna? thirty-seven 

 jointed, scape and pedicellum together distinctly shorter than the first joint of 

 the flagellum; malar space about as high as half the length of the scape. Dor- 

 sulum shining, distinctly punctured, the punctures close together, only the width 

 of a puncture between them; parapsidal grooves represented on the anterior two- 

 thirds of the dorsulum by shallow impressions, converging and terminating in a 

 very closely punctured area ; scutellum punctured like the dorsulum ; mesopleura 

 punctured very like the dorsulum, with a transverse impression in the middle of 

 the posterior half, the impression attaining the posterior margin; metanotum 

 shining, with well-separated punctures, bounded posteriorly by a transverse
