(h) Perhaps a little smaller and paler, otherwise I cannot separate it 

 from (/) " dorsalis var. diluta, Knw." (det. ab ipso). 



(i) Inornata, Cam., is represented by a single 9 at S. Kensington. I 

 have examined it, but can say only that its ground-colour is 

 more brown (less yellow) than in most forms, and that it 

 gives me the idea of a specimen of (c) or some variety near it 

 which had been discoloured to a certain extent accidentally 

 — possibly by too long sojourning in a damp killing-bottle. 

 Consequently the dorsal black vitta shows less by contrast 

 than usual. (Its saw, as figured by Cameron, certainly 

 appears to have features which may be really distinctive. But 

 one would like to see more specimens !). 



I must say that in all the above series I find no positive break at any point, 

 except between (a) and (b) and should have been inclined to consider all from 

 (b) to (i) as one species, but that they are thought to be associated with two 

 very dissimilar $ g , and till this point is cleared up, I do not feel able to form 

 any definite opinion nassata, L., sec. Enslin. 



and 



sp ? (= dorsalis, Lep., sec. Knw.). 



[Since the above was written I have heard from Dr. Enslin that, having 

 examined British specimens sent to him by me of all the above forms except 

 (i), he refers (a) only — the large pale form — to nassata, and all the rest to 

 Konow's " dorsalis," which provisionally he calls " inornata, Cam.," the name 

 dorsalis, Lep., being pre-occupied by an earlier dorsalis, Spin. — F. D. M.]. 



4. Tegulse white or sulphur-yellow, concolorous with the edge of the pro- 



notum 5 . 



Tegulse fuscous black or brown ; if pale brown, at least they are darker 

 than the edge of the pronotum 6. 



5. Hind femora black ; a robust and highly coloured species. Base of meso- 



notum (inner corner of its middle lobes) marked with two paired 

 yellow streaks : this character is liable to be obliterated by unskilful 

 pinning ! The posterior margin of the propodeum ( = med. segment) 

 is conspicuously and broadly yellow. On the abdomen the sides, and 

 two or three dorsal segments, are deep red, but this colour is more or 

 less interrupted by a black central vitta of variable breadth — some- 

 times reduced to a mere line austriaca, Knw. 



— Hind femora red. Much smaller than austriaca, but like it very highly 

 coloured. The tempora are almost entirely white, and there is often a 

 conspicuous pale fascia at the apex of the propodeum. The red of the 

 abdomen is often immaculate ; if interrupted, the black vitta is seldom 

 very noticeable. (I believe that picticeps, C, and flavomaculata, C, are 

 merely varieties of one species. The distinctions drawn between them 

 by the author do not hold good for the specimens in his own collection. 

 In Vol. I the tegulse of these " species " are called * fuscous ' and
