12. HOMALOTYLUS COCKERELLI, new species. 



Plate 39, fig. C 



Female. — Head in general shape much as in //. Jlaminius, being 

 a trifle (about one-thirteenth by measurement) longer tlian wide, 

 and widest across the middle of the eyes; dorsal orbits not strongly 

 convergent behmd, the width of vertex at the posterior ocelli being 

 a little more than half the distance between the lower corners of 

 eyes; ocelli in an ec^uilateral triangle or nearly so, the posterior pair 

 in smaller specimens about one-third more farther apart than dis- 

 tance from either to the anterior ocellus, or to the occipital margin, 

 or in larger specimens (with the vertex proportionately narrower) the 

 posterior pair are a little closer together than space to anterior ocellus, 

 and to the same degrees farther from the occipital margin, ocellar 

 angle about 60° to 75°; the occipital margin more rounded than in 

 //. Jlaminius ; eyes shaped about as in jlaminius but slightly wider 

 below the middle ; the face slightly protuberant between the antenna] 

 sockets. Antennal scape linear, compressed; the pedicel as long as 

 the first funicle joint and three fourths of the second joint combined; 

 the first funicle joint about twice as long as thick, the following joints 

 becoming gradually a little shorter but hardly thicker, the sixth being 

 about a third longer than thick; club nearly as long as the three pre- 

 ceding joints combined. Mandibles v,ith three short subequal blunt 

 teeth, the middle one slightly longer. Thoracic and abdominal 

 structure not deviating from the usual type, the ovipositor protruded 

 for a length about equal to one-half to two-thirds of the length of the 

 abdomen, dependent upon how much the latter is contracted. Wings 

 similar to those of ILflaminius, the medial cross-band of dark colored 

 cilia a little wider, its basal margin much less oblique, and the apical 

 marghi straight instead of a little convex, the subapical oval spot of 

 transparent cilia large, reaching nearly to either margin, its width 

 nearly equal to the apical area of dark colored cilia; stigmal vein 

 distmctly narrowed at its middle, the apex thus appearing more tri- 

 angular than in Jlaminius, the postm.arginal vein equal in length to 

 the stigmal. Sculpture much as m Jlaminius but considerably finer, 

 somewhat so on the head and especially so on the axillae and scu- 

 tellum \vhich are entirely opaque alutaceous, the reticulations of the 

 first tergite of abdomen all a little longer than wide, and their longer 

 axes all rimning longitudinally except across the base of the tergite 

 and not at all coarser at the middle; pm-punctures on head rather 

 numerous but very small and shallow. Length of body (1 .15 to 1 .83), 

 1.73; length of head, 0.565; width of head, 0.535; width of vertex, 

 0.160; length of eye, 0.41; vvidth of eye, 0.24; length of antenna, 

 1.39; width of mesoscutum, 0.55; length of forewing, 1.52; width of 

 forewing, 0.56; length of ovipositor, 0.405 mm.
