the third joint of tlic antennae altogether or for the most i)an.. 

 clear testaceous, the rest black or nearly so ; mandibular teeth 

 dark. 



Head strongly transverse, distinctly impressed along the middle 

 line; in front of the ocelli smooth and shining, but l^ehind these 

 dull and with dense minute sculpture ; antennae shortish and 

 stout, the fourth joint being only as long as the second and hardly 

 twice as long as its greatest width at apex, the third joint rather 

 more than one and a half times the length of the fourth. Prono- 

 tum shining, smooth or almost so, the lobes very distinctl} 

 divided, mesonotal constriction dull and rather short, propodeuni 

 very feebly sculptured on the disc and sometimes dull, l3Ut usually 

 more or less shining, posteriorly transversely rugose, with short 

 and very sparse erect hairs. Front legs with the chelar claw 

 with a minute tooth close to the apex beneath, the trochanters 

 dilating from close to the base; fourth tarsal joint shorter than 

 the first, the fifth with the modified free extremity much less 

 hooked than is usual in Jassid parasites, the lamellate denticles 

 not reaching back to the articular cavity but towards this re- 

 placed by bristles. Abdomen nearly smooth, with scattered hairs. 

 Length 2.5-3 mm. 



This species, resemlbling in color so many others of allied 

 genera from Arizona, is distinguished by the sculpture of the 

 head, the short antennae and the chelae. The latter more nearly 

 resemble those of a Fulgorid parasite than is the case in any 

 species known to me of the Gonatopus s.l. group. However, 

 even had it not been bred, it would have been placed, as certainly 

 a Jassid parasite, by any one familiar with the various forms of 

 the chelae.

2. A'eogoiiafopiis ntiinoidcs sj). nov. 



Ferruginous or testaceous, the petiole black, the mandibles 

 pale yellow with dark teeth. Thin part of posterior and middle 

 femora distinctly paler than the dilated basal part, the tips 

 darkened. Antennae with the three basal joints pale, the rest 

 black or nearly so. Except for the slightly variegated color of 

 the legs almost like the preceding, but more slender and elongate 

 and very distinct by many points of structure. 



Head not very strongly transverse, the eyes much closer to- 

 gether in front than those of A', iiiiiiius, distinctly concave, and
