ribbed, prominently scalloping outer edge, springing from close 

 beneath pseudostigmata as a slender ridge (PL 19, fig. 6), shortly 

 directed ventro-anteriad to rim of camerostome but not extend- 

 ing beyond it (PL 19, fig. h, f) though extending anteriad as 

 prominent cusps, broadly separated from cephaloprothorax (PL 

 19, fig. a,f). Thus these tectopedia extend anteriad much further 

 than is customary in many genera, being remote from insertion 

 of legs I (PL 19, fig. 6). In figure/ one looks directly down on 

 the left tectopedium, so that it appears as an undulate rib. 

 Tectopedia II, seen dorso-ventrally (PL 19, fig. a, e), appear as 

 broadly spoon-shaped ears, housing the tiny pseudostigmatic 

 organs (PL 19, fig. e) which are far above them; seen from the 

 side they appear as long, broad blades (PL 19, fig. h) springing 

 from below pseudostigmata and extending almost directly ven- 

 trad to slightly beyond lower edge of cephaloprothorax; seen 

 somewhat from' side (PL 19, fig. /, where apex is stippled) they 

 have the appearance of a projecting tongue or blade, an edge of 

 which is appUed to cephaloprothorax. In figure a the central 

 ridge indicates their concave, boat-shaped nature; figure d shows 

 how legs I are housed between tectopedia I and II. 



Pseudostigmata not, or barely visible, from above. Figures g 

 and h show the very slight rim as viewed somewhat from in 

 front. Pseudostigmatic organ with head subequal to exposed 

 portion of pedicel, obovate, apex oblique, rather flatly convex, 

 compared to the whole animal unusually small; center filled with 

 eyed, Prunuslike bodies. Lamellar areae porosae invisible or 

 lacking; anterior (figure h) slender, close under rim of notogaster, 

 not visible from above; apodemata I not causing an evagination 

 of sides of cephaloprothorax (PL 19, fig. a). 



Notogaster longer than broad (PL 19, fig. c is of the much 

 broader Hawaiian race), shaped much like a man's cap without 

 visor (PL 19, fig. h), anterior rim gently convex; seen from above 

 the posterior outline is found to vary considerably from rounded 

 to tri-subhedral and from smooth to two furrowed, these furrows 

 evidently being short, vertical grooves, sometimes visible some- 

 times not, depending on angle of vision. They are as remote as 

 twice their diameter, i. e., close to median plane. Adalar areae 

 porosae slender, close to pteromorphae, mesonotical elongate 

 oval, much more approximate than adalar, posterior mesonotical
