Clypeus alone white A. uiicrolciicus. 



More than the clypeus white. 



White facial markings extending a little above the 



antennae A. vidmis. 



White facial markings extending at least as far as 

 the anterior ocellus, along the eye-margins. 



Mesonotum entirely black A. arisomcus (male) 



Meson otum white externally to the parapsidal fur- 

 rows i. pulcherrvmus 



I. Apliclopiis arizonicus sp. nov. 



Pilack, the mandibles except the teeth pale yellow, the basal 

 two joints of the antennae yellow or yellowish brown ; front and 

 middle legs except the apices of the tarsi, the hind coxae, tro- 

 chanters, and basal joint of tarsus, testaceous ; the hind femora 

 and tibiae black or pitchy ; stigma blackish fuscous, the radius 

 curved. 



Head and mesonotum dull, densely minutely shagreened, the 

 parapsidal furrows of the latter distinct, strongly convergent pos- 

 teriorly, visible behind the middle of the mesonotum, but not 

 reaching the posterior margin. Antennae subclavate, the 3rd, 

 4th and 5th joints slender, elongate and subequal, the seventh, 

 eighth and ninth much wider than these, but none of them as 

 wide as long, apical joint one and a half times the length of the 

 preceding ; scutellum decidedly more shining than the mesonotum ; 

 propodeum finely reticulately rugose, posteriorly with a large 

 smoother and shining area defined by raised lines. Abdomen 

 smooth and shining. Length 2 mmi. 



!Male like the female in sculpture, but the two basal joints of 

 the antennae are darker brown, the face below is yellow, with 

 the yellow colour continued upwards along the inner orbits to 

 the height of the anterior ocellus, the legs, except the tips of 

 the tarsi, are entirely clear testaceous ; the stigma is pallid brown, 

 with darker margin. Antennae more elongate and less noticeably 

 subclavate, the eighth and ninth jomts short, hardly twice as long 

 as wide, and shorter than the fourth and fifth. Propodeum not 

 shining posteriorly.
