NO. 3535 MICROLEPIDOPTERA, IX — OBRAZTSOV 593 



area; a rather triangular or somewhat elongate spot at wing apex 

 and apical portion of termen, trivaricate or quadrivaricate toward 

 them; an elongate spot, bivaricate or trivaricate extern ad, located on 

 termen beneath former spot, with lower, internal portion connected 

 with upper portion of a large tornal spot, and thus forming a common 

 tornoterminal spot touching wmg margin at three or foiu- points; 

 preapical costal streak, apicoterminal spot, and tornoterminal spot 

 occasionally connected by means of narrow crosspieces; cilia black 

 in front of markings, and white in interspaces. Length of forewing 

 14-15 mm. Hindwing reddish orange with black spots: a large spot 

 on wing apex, two smaller spots on termen below former spot, and 

 one or two more, smallest, on torn us and dorsum; cilia black in front 

 of spots, white m interspace of apical and upper of terminal spots, 

 sometimes white also m next interspace, and reddish orange in others; 

 some occasional grayish or blackish dots in white or orange interspaces 

 of cilia. 



Male. — Unknown. 



Female genitalia. — Sinus vaginalis flat with a narrow lamella 

 antevaginahs. Antrum cyhndrical, sHghtly longer than broad; 

 two large, lateral colliculi, each with a longitudinal, strongly sclerotized 

 streak. Cervical portion of corpus bursae with a strong, longitudinal, 

 somewhat disorderly striation; no cestum discernible; corpus bursae 

 long and moderately broad; signum ovate. 



Types. — Holotype, 9 (genitalia slide 8678), Cuzco, Peru, January 

 1901 (Garlepp); BM. Paratypes: 9, Peru; DEI. 2 99 (genitaha 

 shde 8677), La Merced ("La Mercede"), Junin, Peru, 2000-3000 ft. 

 (Walkins); B^L 2 99 (genitaha shdes 8675, 8676), Bohvia (nos. 

 71078, 13496); B^L 3 99 (genitaha shdes 4439, JFGC, and 8670), 

 Rio Zongo ("Songo"), Boh^^a, 750 m. (A. H. Fassl) ; B^L 9, same 

 data; USNM. 9, same data; DEL 



Remarks. — In the genitaha this new species is rather close to the 

 new species shafferi and dognini but differs from them in the shape of 

 the colliculi and the striation of the cervical portion of the corpus 

 bm'sae. Moreover, tremewani is completely unlike both of these 

 species in the wing markings. It is more like chrysantheina ]Meyrick, 

 but has the tornoterminal spot never divided, and always separated 

 from the wing margin by several white spaces. The arrangement and 

 the shapes of the spots on the hindwing and the genitalia are quite 

 different in tremewani and chrysanthema. The species is named for 

 W. G. Tremewan of the British Museum (Natm'al History) in rec- 

 ognition of his kind assistance in the dissections of moths; also the 

 author is grateful for haAdng his attention drawn to all characters 

 observed as new or rare in the slides, including this new species.
