26 Mr. G. T. J »#Plune- Baker’s Revision of the 
tegumen moderately developed, the dorsal front apex being well 
excavated with a straightish edge on each side, slightly angled at the 
true fore-apex ; the cheeks then descend in a fairly straight line ; the 
falces are strong, evenly curved, ending in a very long talon ; the 
furca has longish arms, not very wide and curved well backward. 
Penis sheath gradually rising from the hind extremity to rather 
beyond the middle, where it is very broad, then gradually tapering 
to the tip, the front third being somewhat shagreened on its upper- 
side. The tegumen and harpaginea are furnished with hairs.

A species easily to be identified, as the blue is quite different, 
much more lilacine, and decidedly paler than any of the very deep 
blue species that are allied to it ; it is also very much paler on its 
underside, being of a pale clear'grey, as are the markings also. The 
female likewise differs, being pale blue in both] wings above, with a 
prominent dark spot closing the cells, and a broad dark postmedian 
foscia likewise in both wings, the termen being broadly brown ; 
whilst in the secondaries there is an additional dark spot in the 
middle of the cell.

Type in the British Museum. 
Dr. Pagenstecher has been good enough to lend me his 
type of L. nigrocaudata, and it is a specimen of the above 
insect with the basal spot of the secondaries rather obsolete, 
but it is quite visible in one wing under a low-power lens. 
Genitalia .—Harpago almost elliptical, tapering rapidly beyond the 
middle and terminating at the upper and lower extremity in a strong 
tooth. Cingula produced well backwards at the lower base, with 
longish arms, very narrow ; tegumen highly excavated at its front 
dorsal apex with the fore edge of the cheeks very slightly curved ; 
falces long, narrow, deeply curved at a quarter from the socket; furca 
with longish arms, united for a fifth at the base, receding well back¬ 
wards. Penis sheath narrow, gradually increasing for two-thirds, 
then tapering down into a trumpet-shaped orifice. Tegumen well 
furnished with hairs ; harpagines but scantily supplied with short 
hairs.
