SINARISTA; CAEROIS. By G. Weymer. 183 



5. Genus; iSinarista Weyn. 



The distinguisliing characters of tliis genus are the absence in the male of the tuft of hairs between 

 median and submedian on the under surface of the forewing and the form of the submedian of the same 

 •n-ing, which is only elbowed at the base, otherwise almost rectihnear, and only reaches the distal margin 

 in the rounded inner angle, whilst in Antirrhaea it describes a more or less extended curve and runs into 

 the inner margin far before the inner angle. The inner margin of this wing is likewise little curved 

 posteriorly, the distal margin forms a straight line and the ajjex a right angle. The distal margin of the 

 hindwing is produced into a distally directed point at the upper median vein, at the other veins it is 

 only undulate. The single species of this genus has a very dusky appearance and is quite a recent dis- 

 covery. 



S. adoptiva Weym. (44 a). Expanse 8'2 mm. The shape of the wings is that of A. geryon Fldr.-^, adopHru. 

 but the ground-colour even darker brown than in A. geryonides Weym., almost black-brown and uniformly 

 dark all over. On the fore'vs'ing are placed in cellules 2, 3 and 5 three black eye-spots with white pupils, the 

 upper one measuring 5 mm., the two lower only 3 mm. in diameter; on the hindwing in the same cellules 

 thi-ee black spots without pupils, the anterior and posterior spots round, 5 mm. in diameter, the middle 

 one oval and somewhat larger (6 to 8 mm.). These spots stand out but little from the dark ground-colour, 

 sometimes the two posterior ones have fine, scarcely visible, white-grey pupils. The distal margin of- both 

 wings is finely bordered with red-brown, the tips of the fringes white. The under surface is dark brown 

 covered with many fine bluish white dots, which mostly consist of single scales and at the costal margin 

 of the forewing are condensed into a few white spots. Distally this dusting disappears, so that the margin 

 appears unicolorous brown. In place of the eye-spots there are on the upper surface of the forewing 

 three ochre-yellow dots, the anterior one somewhat larger, and on the hindwing in place of the middle 

 spot a small bluish white spot. Discovered by Fassl in the Colombian West Cordillera. The $ of this 

 species is not yet known. 



6. Genus: Caerois Hbn. 



This genus also is distinguished by the possession in the male of a scent-organ at the inner margin 

 of the forewing beneath, moreover on the upperside of the hindwing in the middle of the submedian 

 there is a hair-tuft which consists of a row of brown hairs. The male forelegs are much reduced, the 

 palpi rather long, with thin, curved middle joint, densely scaled anteriorly. The veins are not swollen. 

 In the <S only one subcostal vein arises before the end of the cell on the forewing. The hindwing runs 

 out into a tail at the upper median vein, at the submedian it shows an obtuse angle. The other veins 

 do not project on the distal margin. Large butterflies of 80 — 90 mm. expanse, whose habitat is Central 

 and northern South America. 



C. chorinaeus F. (= arcesilaus S'mZ^.) (44 a). The costal margin of the forewing is strongly cuwed chorinaeus. 

 posteriorly at the apex, the apex itself broadly rounded, the distal margin deepty incised below the apex, 

 the inner angle rounded, the inner margin somewhat projecting. Ground-colour brown with broad red- 

 yeUow oblique band, without eye-spots, only with a white dot before the apex. The distal margin of the 

 hindwing has a red-yellow border 2 — 4 mm. in breadth, the brown point at the upper median vein projects 

 horizontally distad. The brownish ochre-yellow under surface is finely striated with dark brown, with three 

 brown, almost straight and parallel transverse lines on the forewing, of which the middle one only reaches 

 to the median, the hindwing with two lines running in the same direction, which extend from the costal 

 margin to below the middle of the wing, and a third straight line, which connects the apex with the 

 anal angle. The scent-organ of the (Jc? is placed close to the inner angle on the upper surface of the 

 forewing, so that it is not covered by the hindwing; it is 12 mm. long, 8 mm. on the inner and 4 on 

 the distal margin. The anteriorly directed hairs of this scent-organ are 3 mm. long, and dark brown. 

 In addition there is a small brown hair-tuft on the upperside of the hindwing near the inner margin. — 

 Stoll has figured the larva and pupa of this species in the supplement to Cramer's exotic work, 

 pi. YI, fig. 1 and la. The larva has at the posterior end of the body two points of extraordinary length. 

 The body of the larva is 60 mm. long, the points measure 30 mm., thus reaching half the length of the 

 body; they stand straight out posteriorly and are covered with small, fine hairs, whilst the larva itself is 

 naked. The head is proportionately large, red-brown with yellow margins and stripes, the mouth-parts 

 black. The body bears no protuberances, is 5 mm. thick anteriorly and posteriorly and 7 — 8 mm. in the 

 middle, and very gaily marked. Ground-colour reddish violet, venter and legs yellow ; on the dorsum a 

 yellow longitudinal stripe, which is broad in the middle of each segment but narrow in the incisions, so 

 that elongated quadrangles are formed, on which are placed darker yellow and blackish markings and 

 which at each side of the dorsum are bordered by several red-brown and yellow undulate lines. The pupa 

 is suspended, about 22 mm. long, 9 mm. thick, with the abdomen much bent. It shoAvs no sharp-edged
