CONOSTIGMUS UNILINEATUS, Dodd. 



Lygocerus unilineatus, Dodd: Ante, 1915, p. 452. 

 Two females, three males, jungle, 1,300 feet, Cairns 

 district, July, 1915 (A. P. Dodd). Foveae near base of 

 abdomen subobsolete in all these specimens. 



c . Antennae black, the scape and pedicel golden- 

 yellow : scape rather stout : pedicel short and stout ; funicle 

 joints long and slender, the first longest, a little shorter than 

 the scape, the others very slightly shortening toward apex. 



Lygocerus, Foerster. 

 It would seem that this genus can be separated from 

 Conostigmus, Dahlbom, only by the male antenna! characters, 

 and that the females cannot be distinguished. The discovery 

 of the male of unilineatus proved that species to belong to 

 Conostigmus, and it is probable that the other Australian 

 species of Lygocerus founded on female specimens — namely, 

 splendidus, Dodd, aterrimus, Dodd, and albovarius, Dodd — 

 should be referred to the former genus . Whether the two 

 genera should be regarded as separate is questionable. 



Family BETHYLIDAE. 



EUPSENELLA DIEMENENSIS, n. Sp. 



9 • Shining-black ; the coxae and femora concolorous, 

 the tibiae and tarsi deep ferruginous ; antennae wholly yellow, 

 somewhat suffused dusky. Head a little wider than long, 

 dorsal aspect ; eyes large, bare. Pronotum a little longer 

 than the scutum : scutum with complete parapsidal furrows, 

 the lateral lobes with a fine longitudinal groove that fails 

 anteriorly : scutellum as long as the scutum, without an 

 impression at base : head, pronotum, scutum, and scutellum 

 with fine, impressed, polygonal, scaly sculpture, the scutellum 

 with also a very few 7 scattered pin-punctures : metanotum not 

 twice as long as the scutellum, finely transversely rugose and 

 with a median carina. Abdomen as long as the thorax, 

 smooth, or nearly so. Anterior femora distinctly swollen. 

 Forewings long and broad ; faintly infuscate : venation deep- 

 brown ; two closed basal veins ; areole rather small, but plainly 

 longer than wide ; cubital cell one-half longer than the closed 

 radial, which is nearly twice as long as the stigma : radial 

 vein somewhat recurved. Antennae 13-jointed : scape stout, 

 about twice as long and as wide as the pedicel : pedicel as 

 long as first funicle joint, which is two-thirds longer than its 

 greatest width, the others very gradually shortening, the 

 penultimate a little longer than wide, the ultimate as long as 

 the first. Length, 3 '40 mm.
