264 BRITISH TYBOGLYPHIM. 



usually more extruded, the abdomen less square and 

 less flattened. 



The Palmate Hairs on the margin are much longer 

 and narrower than those of the female, and more 

 pointed; the membranous portion is only a strip, 

 but still the construction is similar to those of 

 the female; the spines at the edge are longer than 

 those of the female. The first pair of palmate 

 hairs are set somewhat back on the rostrum, and 

 are straight ; the second pair are small, and are 

 really not palmate, being without the membrane, but 

 assume the form of a central stalk with a few large 

 lateral spines ; the fourth to ninth pairs inclusive are 

 curved and as above described, then come four pairs 

 of hairs which are simply finely and closely pectinated 

 on all sides, resembling the hairs of G. spinipes ; three 

 of these pairs are on the periphery, and one pair set 

 on the notogaster some way from the edge, and about 

 a third of the length of the abdomen from the posterior 

 edge. This last-named pair of hairs (PL XIII, fig. 6) 

 are stout, and far the longest on the body, extending 

 a long way behind the legs. Finally, there are three 

 pairs of broader palmate hairs, more like those of the 

 female, very near together so as to form a bunch a 

 short distance from the posterior margin (PL XIII, 

 figs. 4 and 5). All the body-hairs of the male stand 

 much more upright than those of the female. There 

 are a pair of remarkable, but very small, pinnatifid 

 hairs on the underside (PL XIII, fig. 7), which have 

 not, I believe, been previously recorded. Epimera of 

 the first pair of legs as in the female ; those of the 

 second and third pairs joined by a cross-piece, and 

 also joined to the posterior end of the sternum by 

 another cross-piece. Penis between the third pair of 

 legs. 



Legs much larger in proportion than those of the 

 female ; in particular the two front pairs are far stouter, 

 and the tactile hairs on the first pair are much longer 

 and stronger. The hairs on the genuals of the first and
