A Revision of the genus Tarucus. 295 



black termen and black and white tessellated fringe. Secondaries 

 with an indefinite spot closing the cell, a very oblique row of dark 

 postmechan spots and a complete row of dark subniavginal spots, 

 both these rows occupying the position of the underside pattern, 

 but not being merely the showing through of that pattern; a 

 terminal series of dark spots merging into the black termen around 

 the apex; fringes white with black tessellations at the ends of the 

 veins. Underside white with ash brown spots. Primaries with 

 the subcostal basal stripe, a spot in the middle of the cell with 

 two other spots below it, representing the usual wedge-shaped 

 mark ; a good-sized spot closing the cell with one or two above it, 

 beyond Avhich are three very oblique spots from the costa, with two 

 confluent ones below the lowest of the three, but shifted inwards; 

 two confluent squarish s])ots almost below the one closing the cell, 

 a series of six interneural submarginal marks followed by a terminal 

 row of six distinct sj^ots ; termen consisting of fine black dashes mter- 

 sected with white interneurally. Secondaries : a costal basal spot 

 below which is the basal stripe which is very irregular, four subbasal 

 spots below each other with another small spot from the second 

 connecting it Avith the spot closing the cell; postmeclian series 

 (composed of eight spots) widely separated between the second and 

 the third spots, the lower six forming a very oblique row from vein 6 

 to the inner margin ; all the spots hitherto referred to in the second- 

 ary are somewhat darkly encircled ; submarginal row of seven 

 marks very irregular; terminal row composed of seven distinct 

 spots, the first abo\e the apex very small ; termen with dark dashes 

 intersected with white interneurally. 



Genitalia : these organs are very large indeed when compared 

 with those of the rest of the genus ; the clasps are long, very broad 

 at the base, but taper ra])idly to a narrowish rounded exti'emity ; 

 the cingulum is of moderate and even width ; the tegumen rather 

 small and less excised proportionately; the falces are highly 

 developed, being deeply curved and longish, but of only moderate 

 width ; the aedoeagus is of moderate size, broad and slightly 

 increasing in width to the zone, from whence it gradually tapers 

 for two-thirds of the remaining length ; the apical third tapering 

 very rapidly to a sharp point; the tectorius is ample and well 

 developed, being somewhat of the theophrastus type, but much 

 more ample basally. The androconia are very similar to those in 

 theophrastus, but somewhat larger altogether, they have thirteen 

 rows of lamina that are sculptured rather more finely than in 

 Fabricius's species.
