8. Alaptus immaturus Perkins. 



Perkins, 190.5. p. 197. 



" Alaptus, Hak 



Antennae of female 8-jointed, the scale elongate, the second joint dilated 

 and mtich wider than the following, third slender, elongate, rather shorter than 

 the fourth, 5th, 6th, and 7th, increasing in width, club nearly as long as the four 

 preceding. Antennae of male 10-jointed, the scape elongate, second wider 



than the following, third elongate, but shorter than the fourth, which is sub- 

 equal to the following joints. Posterior ocelli clo.se to the eye-margins, the three 

 forming a triangle with extremely wide base. Tarsi 5-jointed. Abdomen ses- 

 sile. (Plate XII, fig. 5; antennae of female in two aspects, and that of the male.) 

 Alaptus immaturus, sp. no v. 



Female: Pallid ochreous, the head sordid and also the thorax along its 

 posterior margin; abdominal segments with obscttre, sub-quadrate, lateral, 

 blackish or sordid spots. Antennae with two basal joints pale, the rest dark. 

 Length 3-S mm. 



Hab.: Bundaberg, Queensland, bred from cane leaves containing leaf- 

 hopper eggs, but I do not feel sure that it is parasitic on these." 



The descriptive portion under the generic heading refers tO' 

 the species, but the arrangement is unfortunate; the description 

 lacks many details which could just as well have been given. 



9. Alaptus globosicornis species nova. 



Female: Length, 0.1999 mm; wing expanse, exckiding cilia, 0.58 mm.; 

 width of fore wings, 0.0273 mm.; length of fore wings, 0.23 mm. Very minute. 



General color uniformly pale brown; the legs, excluding the intermediate 

 and posterior tarsi, paler; eyes and ocelli red; margins of the fore wings 3'ellowish 

 brown. Body impunctate, smooth. Fore wings norinal, discal cilia entirely 

 absent excepting two distinct soli tar}' ones in a line in the middle of the base of 

 the distal third of the Avings: marginal cilia abrupth' increa.sing in length on the 

 posterior margin at the distal fifth of the wing; the distal cilia largest, at least 

 2 1-2 times as long as the greatest width of the fore wing; fore wings spatulate, 

 gradually widening just bej'ond the basal third which is linear, and widest at distal 

 fifth, the apex narrowly rounded; one margin slightly concaved at distal fifth; 

 distal cilia transparent a short distance beyond their insertion, forming a distinct 

 white path a slight distance from the margin of the wing and following the 

 outline of the distal part of the wing. Hind wings mottled with dtiskj^, Avithout 

 discal cilia, clavate, a short row of cilia near the margin in the wing surface 

 (high power). Body, including antennae and legs, bearing scattered setae. The 

 vertexal carina present, apparently as in caecilii. Thorax and abdomen about 

 equal in length.

From 2 specimens. 2-3 inch objective. Battsch & Lomb. 



Male : — Unknown. 



Barely visible to the naked eye when held to the light. 



Legs normal, the anterior tibial spurs long, slender and curved; apparently 

 two, but if not, then one forked beyond the basal half. 



Antennae pale brown, concolorous with body, the funicle, however, very 

 slightly dusky. Scape, pedicel, and club bearing sparse, scattered, setae; 

 the funicle joints delicately stibverticellate, each with two more or less regular
