NO. 1977. MONOGRAPH OF THE SIGNIPHORIN^—GIRAULT. 209 



inchiding hardly one-third its length, dark brown; wings hyaline, with a dusky band 

 across the middle just beneath the marginal vein, which is a little narrower at the 

 hind margin than at its origin; antennae and legs entirely pale yellowish white. 



Type.— Cat. No. 4855, U.S.N.M. 



Habitat. — West Indies: Trinidad. 



Host. — Rhynch. : Aleyrodes sp. on orange. Two specimens, Ace. No. 6162, Depart- 

 ment of Agriculture. 



This species agrees structurally with Jlavopalliata nearly. How- 

 ever, the discal bristle is absent from the fore wing; the stigmal vein 

 is slightly longer and proximad slenderer, thus with more or less of a 

 short neck; the antennal club enlarging distad, clavate. Otherwise 

 I can not distinguish them. The original description of the species 

 is correct, but not only the whole of the pronotum, but over the 

 cephalic third of the mesonotum is dark brown; also, usually, but 

 not always, the extreme tip of the abdomen and valves of the 

 ovipositor. The dark band of the abdomen includes apparently the 

 first and second segments and is at least a third of the length of the 

 abdomen. Eyes naked; mandibles bidentate, the two acute teeth 

 black at tips; cephalic tibial spur many-tined. The male is like the 

 female. The oblique narrow crease of the fore wing is present but 

 not the discal bristle. The species is somewhat variable in color. 

 The tip of the antennal club may be dusky and a second band may be 

 indicated on the abdomen by the presence of a dark spot on each 

 side at distal three-fourths or even a whole convex band at that place. 



I have studied the following specimens: The types consisting of 

 three female specimens on a single slide in the collections of the 

 United States National Museum, labeled ''Type. SignipJiora aley- 

 rodis Ashm. Bred from Aleyrodes on Orange, etc. Trinidad, W. I, 

 6162." Kelabeled, with type number. Two females on a slide from 

 the collections of the United States Department of Agriculture 

 labeled ''1°3 C. Gn. 2, sp. 3. Saman, Peru. May 25. T." and 

 reared by C. H. Tyler Townsend. (Homotypes.) A slide from the 

 same collection bearing 10 males and 9 females together with the 

 type of Polynema aspidioti Girault and labeled ''1734. Aspidiotus 

 carinatus [ = Lepidosaphes carinata (Cockerell)] on Lime, Cuautla, 

 Morelos, Mex., July 2, '97. Koebele." And fourthly, a slide bear- 

 ing a single female from the same collection labeled "Asp. ficus 

 ['= ChrysorapJialus aonidum (Linnseus)] and A. dictyospermil on 

 Kentia, Westgrove, Pa. A. F. Satterthwait, Feb. 8, 1908." Still 

 another specimen, a male, has been seen, remounted on a slide with 

 the homotype of S.Jiava and labeled "Asp. cameUise, on Acacia sp. 

 Mexico. From A. L. Herrara, Dec. 15, 1905."; and another female 

 on a slide from the United States Department of Agriculture collec- 

 tions, labeled "1453°3a. C. H. T., Lima, Peru. Nov. Gen. 2 d. 

 sp. No. 5, Jan. 16, '10. T." and reared by C. H. Tyler Townsend.
