16. ROMALOTYLUS PUNCTIFRONS, new species. 



Ferroale. — Closely related to H. hyperaspidis and differing structur- 

 ally as follows: Head barely longer than wide and except for the 

 broadly truncated oral margin appearing circular in outline when 

 viewed from in front, width of the vertex at the posterior ocelli 

 noticeably more than one-half the width of the frons at the lower 

 corners of eyes, both of these spaces being greater than in hyper- 

 aspidis; ocelli nearly in an equilateral triangle, the median ocellus 

 being slightly closer to either of the posterior pair than the distance 

 between the latter; eyes considerably narrower than in Tiyperaspidis 

 and hardly perceptibly narrower on the lower half. Antennal scape 

 noticeably slenderer than in Tiyperaspidis and barely expanded 

 apically on the inner margin; pedicel as long as the first funicle 

 joint together with one-half of the second; all the funicle joints 

 longer than thick, the first nearly twice as long as thick, the following 

 gradually shortening, the sixth about one-fourth longer than thick; 

 club (broken off at apex) probably about as long as the last two 

 funicle joints together with one-half of the fourth joint. Mandibles 

 with the three teeth considerably longer and sharper than in hyper- 

 aspndis (or other species), the inner or dorsal tooth being much 

 shorter than the other two. Ovipositor slightly shorter than in 

 Tiyperaspidis, being nearly one-half as long as abdomen. Wings 

 poorly preserved in the unique type, but enough remains to show 

 that they are of the usual tyi^e, the ciliary banding apparently much 

 as in Tiyperaspidis; the postmarginal vein thickened at the base as in 

 that species, but the stigmal considerably shorter and not nearly 

 so slender, being noticeably shorter than the postmarginal with the 

 thickened apical part nearly as long as the slender basal part. Sculp- 

 ture throughout much as in Tiyperaspidis but the pin-punctures on 

 the head considerably more numerous, the minute punctation 

 of the scutellum rather finer and hardly evident under a magnifi- 

 cation of 65 diameters; the reticulations of the first abdominal 

 tergite much less lengthened on the sides and more transversely 

 lengthened at the middle of the posterior margin, and the smooth 

 or nearly insculptate area across the base a little wider. Ijength 

 f body, 1.75; length of head, 0.601; width of head, 0.582; vndth 

 of vertex, 0.188; length of eye, 0.467; width of eye, 0.237; length 

 of antenna (estimated in part, the tip of the club being broken off), 

 1.51; width of mesoscutum, 0.559; length of ovipositor, 0.244 mm.
