424 P. CAMERON. 



Vertex between the ocelli furrowed ; at the sides of them closely 

 obliquely striated; the sides of front distinctly punctured; the face is 

 as strongly but not so closely punctured. Occiput obscurely striated. 

 Pro-, mesonotum and scutellum closely strongly punctured, the latter 

 with a broadly rounded raised margin. Metanotum irregularly, rather 

 closely reticulated all over; the areola small, the base obliquely nar- 

 rowed, the apex transverse. Pro- and mesopleurae smooth, the lower 

 edge of the former and the basal and apical furrows of the latter 

 striated ; the metapleurae if anything more strongly, but not so closely 

 punctured as the mesonotum. The pubesence on the head and thorax 

 is black ; it is much longer on the scutullum. Wings hyaline, the 

 nervures black. 



Mendoza, October. 



6. Spiloclialcis pulchripes sp. n. 



Rufous, largely marked with pallid yellow and with the following 

 black markings : A broad line extending from the anterior ocellus 

 down the front to the antennae, a broad line, narrowed below, in the 

 middle of the occiput, a triangular spot in the centre of the basal slope 

 of the pronotum, an irregular spot on the middle lobe of mesonotum, 

 a smaller pyriform one on the lateral lobes, the greater part of the 

 metamotum, the suture between the pro- and mesopleuree, a large 

 spot, narrowed above, on the lower central part of the mesopleuree, a 

 line on the propleurae at the coxse, and the femoral teeth, black. The 

 following parts are pallid yellow: The face, oral region, the lower 

 eye orbits broadly, malar space, the basal slope, the sides narrowly, 

 the centre broadly, and the pleurae of the prothorax, the outersides of 

 the lobes of the mesonotum broadly, the sides of the scutellum broadly 

 and the sides of the second and third abdominal segments. Legs rufous, 

 the tarsi paler, more yellowish in tint, the apex of the four fore femora, 

 the base and apex of the tibiae, a broad streak on the underside 

 of the hinder coxae, the outer side of the hind femora except for an 

 irregularly large, triangular mark on the basal two-thirds, the basal 

 part longer than the outer, and a spot on the inner posterior fourth of 

 the base. On the upper side of the hind coxae in the middle is a broad 

 black stripe. Femora teeth small, of almost equal size and ten in num- 

 ber. Antennal scape yellowish, the flagellum brownish, darker above. 

 Wings hyaline, the nervures black. 9 and o". Length 4-5 mm. 



Face closely, finely transversely striated. Sides of face and front of 

 vertex strongly puncured, an oblique furrow runs from the fore edge of 

 the lateral ocelli to the eyes ; the part behind this furrow is less strongly 

 and more widely punctured. Pro- and mesonotum and scutellum 

 strongly punctured, the middle lobe more widely than the lateral and 

 finely closely transversely striated. Metanotum closely irregularly 

 reticulated ; the areola triangular, followed by a keel. Propleura;
