2. Ap/iclopiis z'idiiiis sp. nov. 



Male, black, the lower part of the face and the mandibles, ex- 

 cept the teeth, pale yellow or cream-coloured, this colouring 

 reaching- about half way from the mandibles Lo the anterior ocel- 

 lus and not being noticeably carried upwards along the mner or- 

 bits. Front and middle legs pale yellow, the tarsi for the most 

 part infuscate, the hind femora tibiae and tarsi pitchy. 



Head and mesonotum dull, densely shagreened and the latter 

 with the parapsidal furrows distinct and like those of A. ariconi- 

 ciis. Antennae long, slender and filiform, the first two joints 

 dark brown or pitchy, but with the extreme base of the scape 

 yellow, third joint rather shorter than the fourth, which is shorter 

 than the fifth, seventh and eighth almost equal, slender, longer 

 than the fourth or fifth and more than twice as long as wide, 

 tenth joint very slender and elongate. Scutellum, at least poste- 

 riorly, and the postscutellum smoother than the mesonotum, the 

 propodeum reticulately rugose, a posterior area being defined 

 by raised lines and smoother. Abdomen smooth and shining, 

 stigma dark brown. Length about 2 mm. 



HAB. Nogales, Arizona ; collected on weeds in September. 



3. AplicJopiis puJchcrrinius sp. nov. 



Black, the whole face creamy white, this colour reaching almost 

 to the anterior ocellus and at the sides is continued upwards as 

 far as the posterior ocelli along the orbits, the outer orbits being 

 also of the same colour ; scape of antennae and all the legs whit- 

 ish or pale yellow ; also the whole of the mesonotum is cream- 

 coloured exteriorly to the parapsidal furrows, and likewise the 

 whole thorax beneath and the pleural portion. Antennae, except 

 the scape, testaceous ; wnngs with brown stigma. 



Head and thorax sculptured as in the two preceding species, 

 posterior area of metanotum dull, minutely shagreened. Anten- 

 nae with the second and third joints shortish, not dififermg much 

 in length, but the fourth is rather longer than the third, and suIj- 

 equal to the fifth. Abdomen smooth and shining. Length 

 1.5 mm. 



Owing to their delicate nature the antennal joints have more or 

 less collapsed and I cannot exactly make out the true shape 01 

 some of them, nor am I certain of the sex of the single example. 



HAB. Nogales, Arizona ; bred from a species of Typhlocyba 

 (Zytriiin) no. 2455.
