 Doryctes incertus u. sp. 



Female. — Length, 5 n,IU ; ovipositor, l mm . Black; legs honey-yellow ; 

 abdomen beneath more or less rufous. Head quadrate, the vertex 

 smooth, polished, face rugose; thorax rugose, the parapsidal grooves 

 distinct anteriorly, obliterated posteriorly, the surface of middle lobe 

 posteriorly depressed and coarsely rugose just in front of the scutellum ; 

 mesopleura smooth with a large groove across the disk ; teguhe yel- 

 low ; metathorax finely rugose and areolated with distinct raised lines, 

 the two basal areas large, quadrilateral; abdomen ovate, about as long- 

 as the head and thorax together, the 1st segment coarsely, longitu- 

 dinally striate, the following smooth and polished; the segments of this 

 portion of the abdomen are so finely separated that the whole surface 

 has the appearance of one solid polished segment. Wings hyaline, 

 very slightly dusky; the veins pale brown. 



Described from a single specimen, without locality, but taken prob- 

 ably at Washington, D. C. 



Doryctes mellipes n. sp. 



Female. — Length, 5 mm ; ovipositor, l| mm . In stature and color this 

 species agrees exactly with D. incertus, and in sculpture, excepting it 

 is more coarsely rugose. The vertex of the head is not smooth but 

 rugose; back of the ocelli the rugosities become transversely striate; 

 the thorax is uniformly rugose, coarser than in I), incertus; the upper 

 margin of the mesopleura beneath the wings is rugose, while the meta- 

 thorax is not as distinctly areolated and the ovipositor is longer; other- 

 wise similar. 



Habitat. — Central Missouri. 



Described from one specimen, labeled " Parasite from a borer in de- 

 cayed cherry-wood, April 27, 1888." 



Doryctes texanus n. sp. 



Female. — Length, 5 ram ; ovipositor, 5| I1,m . Brown; thorax black; legs 

 rufous, the anterior and middle pairs more or less yellowish. Head 

 transversely striate above; palpi long, pale yellowish ; antennae long, 

 very slender, multiarticulated ; thorax rugose, the parapsidal grooves 

 distinct ; metathorax slightly longer than high, rugose, with two slight 

 keels posteriorly where the abdomen is attached; abdomen (J jointed, 

 shaped somewhat as in Ghelonus, as long as the head and thorax to- 

 gether, rugose, the rugosities somewhat longitudinally directed on the 

 1st and 2d segments; the 3d and following short segments much 

 smoother; the 1st and 2d segments comprise three-fourths of the length, 

 the 2d being the longest; the 1st has two keels at base hardly extend- 

 ing tothe middle of the segment, the 2d has an undulated cross-furrow 

 beyond the middle, and another cross-furrow just back of it. between 

 it and the apex of the segment which curves just before reaching the 

 lateral margins and connects with the first, thus forming on the segment 

 a transverse incised space which will readily distinguish the species j
