IlAiJiTAT. — Jacksonville, Fla. 



Type S in Coll. Ashmead. 



BOCCHUS A.sliiii., iicii.uov. 

 (Type /.'. tlorivollis Aslim., 9 .) 



Head large, broad, shaped much as in Dryinus, but the vertex not 

 impressed, the occiput very slightly concave; eyes large oval, promi- 

 nent; ocelli small, close together in a triangle. Antenme 10-jointed, 

 subfiliform, very slightly thickened toward tips, inserted Just above the 

 clypeus, the scape longer than the first flagellar joint. 



Maxillary palpi 4-jointed. 



Mandibles 3-dentate, neaily equal, the inner tooth a little the smallest. 



Thorax not much lengthened, much narrowed anteriorly and trun- 

 cate posteriorly, the angles of the truncature rounded; the pronotum 

 is almost as long as the mesonotuiu but nnich narrowei-, a little wider 

 anteriorly than at base, only about half the width of the very broad 

 head; mesonotum wider than long, with furrows; scutellum semicircu- 

 lar with a transverse furrow all across the base; metathorax much 

 shorter than high, abruptly truncate. 



Front wings with a lanceolate stigma, two basal cells, nnd an open 

 marginal cell, the radius being long and curved. 



Abdomen globose, distinctly i»etiolate, the petiole blender, cylin- 

 drical, as long as the hind coxa?. 



Legs as in Dryinus, the anterior tarsi chelate, the fourth Joint not 

 much larger than the third. 



This genus comes nearest to Dryinus, but is at once separated by the 

 4-J<)inted maxillary palpi, the difference in the shape of the prothorax, 

 the globose abdomen, the relative length of the anterior tai\sal joints, 

 and by the vertex of the head not being impressed. 



Only a single species is known, as follows: 



Bocchus flavicollis, sp. nov. 

 (PI. V, Fig. 6,9.)

 mesonotum tinged with brown. Head large, broad, subquadrate, not 

 impressed on the vertex, a little narrowed behind the eyes ; eyes large. 

 Prothorax strongly contracted, yellow; two basal Joints of antenna^, 

 the legs and i)etiole pale rufous; flagellum subclavate, brown black. 

 Antenuii? 10-Jointed, the i)edicel about half the length of the first flagel- 

 lar joint, the first being about as long as the scape, the remaining Joints
