SCHOENBERGIA GOLIATH. *. 



Troides Goliath, S. Rothschild, "Novitates Zoologies," Vol. xi, page 311. (1904)- 



Since writing the preceding pages, and drawing the 

 plate of Sch. Titan, I have had the opportunity of study- 

 ing and figuring the true <? of Sch. Goliath, and the true 

 ? of Sch. Titan ; by which it will be seen that though 

 there is a significant similarity between the two nominal 

 species, there are yet some important differences between 

 them, especially in the females ; and it will be evident that 

 Titan can only take rank as a local variety, or at most as 

 a subspecies of the former. 



$ Anterior wings : above intense velvety black and rich 

 golden green — the areas of each being arranged almost in 

 the same design as is Grose-Smith's Titan, with the follow- 

 ing small differences : — The base of the wings in Titan is 

 not entirely black, as two subcostal green lines from the 

 base enclose the subcostal nervure, while in Goliath this 

 is not the case, in the example before me — the base being 

 black. In Goliath the space between the 3rd median 

 nervule and the submedian nervure is plentifully sprinkled 

 with the black scales, which on the nervure become a grad- 

 uated black patch reaching nearly to the outer marginal 

 band of the wing : in Titan this space is almost free from 

 the black scaling : the black scaling is also more extensive 

 in Goliath than in Titan ; and the general green of the 

 wing, though in some lights more golden, has not in any 

 light the vivid tint of yellow as in Titan ; when viewed 

 obliquely against the light the anterior wings are as golden 

 as is O. Crcesus. The most vivid green is on the costa of 

 the wing. 



Posterior wings : vivid silky golden yellow as in Titan — 

 all the veins showing conspicuously in black or intensely 

 rich green — much more so than in Titan ; the 3 discal 

 orbicular spots are of the same prominent green, the low- 

 est of the three being the largest, and enclosing a small 

 black spot or pupil ; the black marginal border and the black 

 submedian areas are edged with the same green : and from 



the band of the wing the inner or abdominal margin has 

 also a short curved green line. 



Under surface of anterior wings : similar to that of Titan, 

 with the following exceptions : the upper margin of the 

 discoidal cell along its entire length is rather broadly 

 black. The space between the 4th and 5th subcostal ner- 

 vules is nearly entirely black, with a green latitudinal 

 stripe nearest the outer margin, and the submedian black 

 is rather more extensive than in Titan. The wings very 

 golden green — almost yellow, but the upper and outer 

 parts of the wings are a deep green. 



Posterior wings as in Titan, except that the discal 

 black spots are smaller in proportion, and the lowest nearly 

 square, and slightly edged with green, the inner golden 

 yellow is silky brownish-golden. 



Thorax, head and antennae as in Titan ; eyes black ; 

 abdomen not quite so ruddy yellow as in that variety. 



Length of Costa 82 mms.; of outer margin about 45 

 mms.; greatest length of posterior wing 50 mms. ; greatest 

 width of wing 36 mms. ; length of abdomen or antennas 

 34 mms. ; of thorax with head, 22 mms. 



Length 

 of Legs 



1st pair : femur, 12 ; tibia, 9 ; tarsi, 14 mms. 

 2nd „ ; ,, 13 ; „ 14 ; „ 18 ,, 

 3rd „ ; ,,13: 14; „ 18 „ 



Habitat : Geelvink Bay, Dutch New Guinea. 



The great similarity of this form to Mr. Grose-Smith's 

 Titan indicates that Oberthiir's Goliath is entitled to stand 

 as a representative species, and Titan as a local variety of 

 Goliath.
