Subfamily Aphelinin^. 



Tribe ApJiclini)ii. 



Genus PARAPHELINUS Perkins. 



A genus similar to Aphelinus Dalman but dififering in the following 

 particulars ■} The antennae are longer and more slender, both funicle joints 

 longer than rvide, not wider than long ; the fore wings are narrower (about 

 3j4 times longer than wide) and with a conspicuous sooty black band across 

 them, this band deep black not merely embrowned as in Aphelinus fuscipennis. 

 The ovipositor is exserted for about a fifth the length of the abdomen. The 

 body is stout and large for the subfamily, the mandibles tridentate, the two 

 outer (lateral) teeth acute and subequal. Otherwise as in Aphelinus. Also 

 allied with Centrodora Foerster but differing in the black-banded fore wing 

 and more distinct 2-jointed antennal club, as well as in having naked eyes, 

 unequal funicle joints and one joint less in the antenna. From Perissopterus 

 Howard it differs in not having the characteristic maculate fore wings and in 

 lacking the "ring-joints" in the antennae. The genus is based on a species 

 occurring in Hawaii ; the following North American form has been captured 

 recently by me and forms the basis for the generic characters just given. 



Paraphelinus speciosissimus, new species. 



Normal position. 



Female. — Length, 1.45 mm., including ovipositor. 



General color black, the thorax yellow, excepting the tegulae, axillae, pro- 

 notum and scutellum, which are dusky black ; median line of scutellum yellow ; 

 funicle and club of antenna yellow ; head suffused with some yellow ; all of 

 legs concolorous with yellow of the thorax excepting the caudal coxae and 

 femora which are black; caudal trochanters pallid; distal tarsal joints not 

 darker. Mandibles fuscous ; eyes dark. Both wings hyaline but the fore wing 

 crossed by a conspicuous sooty band beneath the whole length of the marginal 

 and stigmal veins, the band nearly as wide as long, its margin (proximad and 

 distad) not straight, the distal margin irregularly concaved. Venation dusky 

 yellowish. The whole fore wing has a slightly darker shade than the posterior 

 wings. 



Scutum and scutellum with a median grooved line, the scutellum polygonally 

 sculptured. Fore wings regularly rounded, the marginal fringes short, very 

 short along the cephalic margin, the discal ciliation uniform, close, fine, the 

 oblique hairless line running through the black band ; the subtriangular patch

 below.
