Aranea westringii Thor. 



Extremely like A. ciiairbitiua Clk., but the thorax 

 of the male lacks the lateral blackish bands. Ex- 

 tremely rare. 



Aranea triguttata Fabr. {Epeira agalena in 

 " Spiders of Dorset.") 



Length. Male 4 mm. , female 6 mm. 



Cephalo-thorax warm yellowish-brown, palest in 

 front. Anterior central eyes seated upon a slight 

 prominence. Abdomen reddish-lirown, speckled 

 with yellow. " Shoulders " very dark. Not rare. 



Aranea redii Scop. {Epeira soUcrs\\\ " Spiders 

 of Dorset"; E. solers VA.) 



Length. Male 6 mm., female 8 mm. 



Allied to A. trigiittata Fabr. , but much lar^^er. 

 The process connected with the genital aperture of 

 the female, also, is shorter and straighter than in 

 that species. Not rare. 



Aranea acalypha Wlk. {Epeira acalypha in 

 "Spiders of Dorset.") 



Length. Male 2.5 mm., female 5 mm. 



Anterior eyes, in the male, almost equidistant. 

 Quadrangle formed by the centrals longer than wide. 

 Anterior central eyes in the female hardly as large 

 as posterior centrals, and separated by a distance 

 greater than that between one of them and the ad- 

 jacent lateral. Not common.

BUTTEKFLIES OF THE PALAEARCTIC REGION.

{Continued from page 268.) 



LYCAENIDAB. ( Continued.-) 



Genus 2L SATSUMA, Murray 1875, Stgr. Cat. 

 190L Theola Led., etc. ; ? Incisalia Scudder. 



Small butterflies, attaining about the same 

 dimensions as Callophrys ruhi. Wings rather short 

 and broad. Ou. margins more or less crenate, 

 especially those of h.w., which are most markedly 

 indented towards anal ang., but without any 

 " tail." There is a peculiar lobe-like projection at 

 an. ang. Sub-costal nervure four-branched. Eyes 

 hairy.

 t. 1, 1 1, R.H. p. 194; Stgr. Cat. 1901, p. 68. 



23—28 mm. 



The greater portion of the wdng area is of a 

 light metallic blue colour, similar to that seen in 

 some species of Lycaena. F.w. with costa and 

 ou. marg. broadly blackish-brown. H.w. with a 

 narrow dusky marginal band, external to which is 

 a narrow blue line, and then a black one. Fringes 

 black and white. Neuration black. Head, thorax, 

 and abdomen blackish. Antennae black, with 

 white rings. Clubs black. U.S. sepia-brown. 

 F.w. with a wavy darker line, faintly edged with 

 white externally, at end of disc. cell. H.w. with 

 three distinct dark brown wavy lines, reaching 

 from costa to in. marg. The space between the 

 first and second Jines is darker than the rest. 

 Basal portion and ou. marg. powdered with greyish- 

 white. The sexes differ but little in markings, the 

 $ being somewhat less suffused than the S . 



Hab. Altai, -S.E. and C. Siberia, Amur. V.-VI. 



Mr. H. J. Elwes, in his monograph on the 

 Lepidoptera of the Altai Mountains, Trans. Ent. 



Soc. Lond. 1899, p. 321, remarks concerning this 

 species as follows : — " I found this in bushy places- 

 in the Katuna and Tchuja valleys at 3,000-4,000 ft. 

 in the second week in June. It is evidently an 

 early spring insect, as many of the examples were 

 already worn. It appears to be common through- 

 out Central Siberia, as Jacobson found it on the 

 Upper Yenesei, Leder on the Irkut, and Trybom on 

 the Lower Yenesei as far north as 64°. This 

 species is probably more nearly allied to the North 

 American group of which T. irus Godt. is the 

 best-known representative than to any European 

 species. This group has been generically separated 

 by Scudder under the name Incisalia. It is quite 

 distinct, in my opinion, from Thecla (^Batswna') 

 ferrea from Japan, both by the pattern of the 

 underside and by the absence of the sexual patch 

 on the fore wing of the male." " Non syn. ferrea 

 Butler," Stgr. Cat. 1901. 



Genus 22. NIPHANBA Moore. 



Butterflies of larger expanse and of a more- 

 robust ' appearance than those of the foregoing- 

 genera. Fore wings pointed at apex in $. H.w. 

 ending acutely at an. ang. ' In 9 wings altogether 

 more rounded, but the ou. margs. of all the wings 

 in both sexes are entire, without indentations or 

 projections ; and there are no " tails." The under- 

 side of the wings is not streaked, but has dark 

 spots disposed in rows or chains, and sur- 

 rounded by whiter rings, very much as in some 

 of the Lycaenae. Byes smooth. Antennae as 

 in the preceding genera. Thorax and abdomen 

 less slender. Subcostal nervure of f.w. three- 

 branched.
