Psyche 
[June 
almost transversely; with a deep trough on external surface; medial 
ends terminate in what appears to be a characteristic manner (Fig. 
28). Lip: essentially typical of males of the genus; sternal suture 
not observed and, therefore, lip is regarded as immobile. Sternum: 
convex; third coxae subglobose, others more elongated; otherwise 
essentially typical of the genus. Legs: 4123 in order of length; tibial 
index of first leg 11, of fourth leg 8; spines appear to be absent as 
usual but there are many erect bristles, especially along dorsal sur- 
face of femora; two tarsal claws as usual; trichobothria observed 
on tibiae and metatarsi. Palp: essential features shown in Figures 
29-32 ; left palp fully developed and, in general, quite typical of the 
genus; right palp not inflated and much smaller; the conspicuous 
unilaterality of the functional palp is the normal condition in this 
species as in S. gertschi Chickering and not an anomaly as at first 
thought; some variation in the degree of development of the right 
palpal tarsus has been noted, however^ among the many individuals 
available for study; fine striations are clearly visible on the prolateral 
Figures 36-41. Scaphiella septella sp. nov. Figs. 36-38. Male palpal 
tarsus; prolateral, retrolateral and ventral views, respectively. Figs. 39-40.
