944 LORD WALSINGHAM ON THE [NoV. 26, 



specimens on the same spot on May 10th, when I t'ouml the larva 

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

 was hitherto unknown. 



44. (2270-02) Trichotaphe convolvuli, sp. n. 

 (Plate LI. fig. 16.) 



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

 ■(1892) \ Brachmia {Ceratophora) sp. Rbl. Ann. KK. Hofmus. 

 XXI. 44 no. 216(1 906) ^ 



Antennae dark tawny fuscous. Palpi, dull whitish ochreous, 

 unspotted ; the median joint clothed with closely appressed scales. 

 Head whitish ochreous. Thorax dark tawny fuscous. Fore wings 

 dark tawny fuscous, with a small, narrow, elongate, pale ochi-eous 

 ■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 wdth chestnut- 

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

 first discal, and a row of minute ochreous spots pi-ecedes the dai-k 

 tawmy 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 taAvny 

 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 difters 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.

 — Grax' Caxaria : {Richter) ^~'. 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 Innately, suture 

 iioney-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 latei'al 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-VII by a transverse bar of the same colour, but on 

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

 noi-mal spots distinct, black ; legs black, abdominal claspers 

 tipped w-ith blackish ; long. 15 mm. (99006 Mus. Wlsm.). The 

 larvae I'oll the leaves oi Ipomoea quinquefolia in January, and are 

 extremely abundant on this introduced plant at Santa Cruz, 

 especially on a Avail below the Quisisana Hotel.
