In Fig. 5, an interesting Syrian species of which M. 

 Abeille de Perrin has kindly given me several examples, 

 the process is dilated towards the apex, but its outlines are 

 not otherwise abnormal ; the pilosity, however, gives it a 

 truly paradoxical appearance. A pair of thick and very 

 long lateral brushes, starting from the geniculation, sweep 

 round in bold semicircular curves encircling the apex, and 

 almost meeting beyond it. 



It has been suggested that scliendd, Mor. (Fig, 6, 6a), 

 is a mere colour-variety of lahialis, Kirby (Fig. 10, 10«). 

 I feel sure that any one comparing their valvuLv ventrales 

 will see that this is quite impossible. 



The species which in all characters (terminal included) 

 come nearest, among those I have examined, to lahialis, 

 are decipiens, Schenck (Fig. 11), and variabilis, Smith. 

 The precise agreement of these latter species in the 

 characters of the 8th segment with ovina, Klug (Fig. 9), is 

 very curious, for their general facies is extremely different, 

 and their armatures are easily distinguished. It is hard 

 to see how they can be brought near it in any natural 

 system of groups. 



Fig. 8. The bottle-like outline of the process in this 

 species (ficcata, Smith) separates it very easily from those 

 most resembling it, e.g., varians, helvola, amhigua, a'picata, 

 laip-ponica, etc. In all these the sides of the process are 

 very gently and evenly sinuated throughout : it is about 

 equally broad at base and apex and narrowest half way 

 between them. Figs. 18 and 18a appear to show an 

 extraordinary development of the character just noticed in 

 fucata. The apex is almost ridiculously narrow and 

 produced, but the sides of the process dilate abruptly and 

 become convex towards the geniculation. This (JIcssib, 

 Panz.) is the species whose extraordinary armature is 

 shown in Plate V, Fig. 17, with its huge lobes and meagre- 

 looking short and narrow processes. I may note, also, 

 that the constriction of the 8th segment between its basal 

 plate and its process is very sudden, giving to the latter a 

 strongly " shouldered " appearance. 



Figs. 14, 14a, 15, 15a. These strange forms, with the 

 lateral projections of the process each ending apparently 

 in a little hook, were long utterly unintelligible to me. 

 But by comparing their lateral views with Figs. 9a, 10a, 

 etc., I believe I can now understand them. The hook- 

 like tips seen in the ventral views, appear in the lateral
