 Ftiscus, subpuhescens ; vertice, prothorace, extremitate mesothoracis, scu- 

 tello, metathorace et peduncuU disco nigris. 



Reddish fuscous, with the vertex, the prothorax, excepting its lateral angles, 

 the discal portion of the extremity of the mesothorax, the scutellum, 

 metathorax and disk of the peduncle of the abdomen, black ; head small, 

 ocelli large and prominent, and disposed in a very open curve, with 

 less than the diameter of one between the anterior and posterior; an- 

 tennae moderately long, setaceous, the scape very slightly thicker than 

 the base of the flagellum, and about one-fifth its length ; carinas of the 

 face comparatively slight and parallel, terminating gradually in front 

 of the anterior ocellus ; mandibles very slender and much curved, lea- 

 ving but a small space between them and the clypeus. 



Thorax very gibbous at the scutellum, and the metathorax abruptly perpen- 

 dicular ; wings hyaline, their nervures testaceous ; the marginal cell 

 considerably larger than either of the two first submarginals, lanceolate 

 and slightly acuminated beyond the second submarginal, which is 

 rather smaller than the first, from which it is separated by an undulated 

 transverso-cubital, and has the recurrent nervure inserted at half its 

 length, beyond which to the end of that cell the cubital nervure is con« 

 siderably thickened ; legs short and rather stout. 



Abdomen slightly shining, its peduncle transverse-quadrate, the disk con- 

 vex, scarcely so wide as the second, which to the sixth are short and 

 transverse and slightly constricted ; the terminal segment considerably 

 vertically compressed at its extreme apex, and the sexual organ pro- 

 truding beneath it in the form of two curved and tolerably compressed 

 teeth, convex beneath. 



In my own collection. 



The proportions of the body of this insect are somewhat similar 

 to those of the L. Swainsoni, but it is rather more robust, and dif- 

 fers from it in the neuration of the wings, colouring of the body, and 

 other minute particulars ; besides being much larger. I have dedi- 

 cated it to the celebrated and talented lUiger, whose attachment to 

 the Hymenoptera is conspicuous throughout all his entomological 

 works. 



The next species will immediately precede the L. Klugii, viz.

Fnscus subpuhescens ; capite atro, scapo antennarum incrassato, et clypeo 

 tuberciilis binis acutis recurvis histructis. 



Dark fuscous, especially the thorax and peduncle of the abdomen : the 

 head small, very black and shining : ocelli large, placed in a curve, 

 and with less than the diameter of one between the anterior and
