944 LORD WALSINGHAM ON THE [Nov. 26, 



specimens on the same spot on May 10th, when I found the larva 

 feeding on Convolvulus althaeoides : the food-plant of this species 

 was hitherto unknown. 



44. (227O02) TRICHOTAPHE CONVOLVULI, sp. n. 

 (Plate LI. fig. 16.) 



= Ceratophora sp. Rbl. Ann. KK. Hofmus. VII. 275, 283 no. 58 

 (1892) 1 . Brachmia (Ceratophora) sp. Rbl. Ann. KK. Hofmus. 

 XXI. 44 no. 216 (1906) 2 . 



Antennae dark tawny fuscous. Palpi dull whitish ochreous, 

 unspotted ; the median joint clothed with closely appressed scales. 

 Head whitish ochreous. Thorax dark tawny fuscous. Forewings 

 dark tawny fuscous, with a small, narrow, elongate, pale ochreous 

 costal spot at four-fifths from the base ; on the cell, at one-third 

 from the base, is an elongate blackish spot, followed by another 

 at two- thirds each rather obscurely annulate with chestnut- 

 brown scales ; a similar spot lies in the fold, straight below the 

 first cliscal, and a row of minute ochreous spots precedes the dark 

 tawny grey cilia. Exp. al. 13-15 mm. Hindwings brownish 

 grey, with a slender pale ochreous line along the base of the 

 otherwise unicolorous cilia. Abdomen fuscous. Legs dark tawny 

 fuscous ; the spurs and joints of the tarsi pale cinereous. 



This species (which is obviously the same as Ceratophora sp. 

 Rbl.) is closely allied to juncidella Clms., but differs in its darker 

 face and palpi : the median joint of the palpi is more roughly 

 scaled, and the pale costal spot is distinctly visible on the under 

 side of the forewings. 



Type $ (99004); <$ (99005); (99006) Mus. Wlsm. 



Hah. Canaries TENERIFE : Santa Cruz, 19-22. I. 1907, 

 Ipomoea quinquefolia, 19. 1, excl. 20. II - 2. III. 1907 (Wlsm.). 

 GRAN CANARIA : (Richter) 1 ~~. Thirty- two specimens. 



Bred from larvae reminding one much of those of Brachmia 

 rufescens Hw. in their black and white oblique striping. Head 

 honey-yellowish, edged with blackish ; pronotal plate honey- 

 yellow, posteriorly broadly black - margined lunate! y, suture 

 honey -yellow ; mesothorax, metathorax, and abdominal somites 

 I-II blackish, mesothorax conspicuously separated by white from 

 the metathorax and prothorax, the latter similarly separated 

 from the head ; abdominal somites III-IX white, with blackish 

 markings the lateral markings are oblique, as in rufescens, but 

 having no pale dorsal stripe to interrupt them, anteriorly above, 

 they form on each segment a complete arcuate band, followed on 

 somites III-YII by a transverse bar of the same colour, but on 

 Y this bar is not apparent, owing to dark dorsal suffusion ; 

 normal spots distinct, black ; legs black, abdominal claspers 

 tipped with blackish ; long. 15mm. (99006 Mus. Wlsm.). The 

 larvae roll the leaves of Ipomoea quinquefolia in January, and are 

 extremely abundant on this introduced plant at Santa Cruz, 

 especially on a wall below the Quisisana Hotel.
