AvSTHENOTRIC'HA. By L. B. Bkout.

most Larentiids. Warren adds that the 2iid sid)costal of the hindwing is not stalked, hut this — if not. an 
error of observation — must refer to a rare abnormality, as I find it quite shortly to quite considerably stalked. 
In 1915 I proposed making AstJienotricha a section of Hydrelia, but subsequently 1 flecided to conserve it 
until the relation between the Afrcian and the Palaearctic elements had been more tluu’oughly investigatefl. 
All the Asthenotricha are African. 
A. semidivisa Warr. (12 f). Recognizable by the blackish costal tuft of the hindwing, the pale ])atch xcmidh-lsa. 
around the blackish cell-dot of the forewing and the dark longitudinal streak in front of the 3rd radial of the 
forewing from the (blunt) angle of the postmedian to the termen. Founded on a A from Kiwalogoma, Uganda; 
forms which are probably conspecific have been sent from Kavrrondo and ])erhaps (a small ab. 1) from Bitje, 
Ja River, 8. Cameroons. We figure a well-marked from Nabagulo Forest, near Kampala. — euchroma Profit ei'chn/md. 
is a trifle larger (25 mm against scarcely 24), more brightly coloured, the pale stramineous ■])arts of the forewing, 
excepting the tornal region, irregularly suffused with bright ochreous and reddish, the median area predominantly 
bright red-purple, the longitiidinal streak rather thick, varied with ])ur]de and reddish. Mikeno Mountain, 
N. Kivu. 
A. straba Frt. (12f). Very similar to the preceding. Distal margins slightly more crenulate, groTind- ■'simhti. 
colour more uniformly suffused wdth bright ochreous, lines more slender, cell-dot much smaller, placed close 
to the proximal margin of the white spot, longitudinal streak very slender, hair-tuft of hindwing strong, bright 
oehreoiis with very little dark admixture. Kivu (loc. typ.). Mounts Kenya and Aberdare and Angola. 
A. atisorgei Warr. was founded on a worn A ft'om Nandi Country, Ftganda, and it is not yet quite certain unsoryei. 
that it may not have been a form of the preceding (in which case the name ansorgei would have priority), al¬ 
though the hair-tuft of the hindvdng seems to have been drdl yellow, with fuscous ti])s. I believe, however, 
that an Asthenotricha which is distributed in Kenya Colony and known from Toro (Uganda), Kilimandjaro, 
and I think Ruwenzori is a more probable claimant; except that the proximal band of the hindwing is a little 
less excurved in the middle, it seems to agree well with the type. Perhaps intermediate between senhidivisa 
and straba. 
A. flavicoma lUarr. (12 f) is the first of a difficult group of close allies which have not yet been com- flavicotna. 
pletely disentangled. The general tone of flavicoma is perhaps “vinaceous-buff" of Ridgway, vith a tinge of 
"vinaceous-fawn'’, the hair-tuft of the hindwing “antimony yellow"’. Markings not very sharp, cell-dots small, 
beneath weak, 1st postmedian line of forewing well beyond cell-dot, somewhat angled near costa. A dark 
median spot at hindmargin of forewing is indicated or strong. Uganda (the type from Ran, Nandi Country), 
Busiro, Entebbe, etc.; also from a few locahties in Belgian Congo and 8. Cameroons. 
A. amblycoma s'p. n. (I2f). Expanse 24—25 mm. Perhaps near semidivisa, straba and ansorgei in the amblycoma. 
concise band (or double line) of the hindwing and the degree of development of the rather dull hair-tuft; the 
relatively uniform coloration of the forewing is more as in flavicoma and some pycnoconia. Ajiparently some¬ 
what va’iable, but the smaller size, duller colour (no clean cinnamon or ochraceous tone observable except on 
the very narrow band which edges the postmedian line), less firm postmedian line and especially the almost 
simple cj antenna and very different hair-tuft separate it readily from the other new Fernando Po Astheno¬ 
tricha, described below. Mr. Tams obtained 3 Moka, 29 January — ^3 February 1933. A possible race, 
in poor condition, occurs at Bitje, 8. Cameroons, with perhaps more superficial resemldance to flavicoma; 1 (J, 
from the Joicey collection. 
A. pycnoconia {Prout, M8.) Janse (12 g). Lamellae of the A antenna a little less strong than in flavi- pycnoconia. 
coma and anisobapta, costal lobe of ^ valve (according to Janse) longer and narrower than in flavicoma. 8 hghtly 
browner than that species, ante- and postmedian lines rather sharply expressed, their colour a characteristic 
bright hazel, the anteniedian rather sinuous, postmedian of forewing with a small outward angle at the 1st 
radial, of both wings edged distally by a fine, very pale yellow line. C^osta of hindwing possibly still more strongly 
arched than in flavicoma, forewing above with grey patch of specialised scaling still more noticeable than in 
that species. My studies were founded chiefly on material from Uganda and especially the Kilmyu Escarpment, 
but Janse has described from Woodbush and other localities in the Transvaal, and his form perhaps differs 
from the East African in having the median area rather narrower, especially in the the anteniedian closer 
to the cell-spot. Capo Colony also produces this species. 
A. lophopterata On. (12 g). This, the earliest-known Asthenotricha, ivas described by Cfenee as an lophoptera- 
Acidalia! Although the original came from Madagascar, its headquarters seem to be on Reunion. Warren, 
in erecting his flavicoma, suggested that it might possibly be identical Avith lophopterata, but the latter is a 
larger species, more fuscous and more strongly marked, perhaps more similar to pycnoconia . Further com¬ 
parisons are offered under the folloAUng form, which I take to be the continental subspecies of lophopterata. 
— ■ anisobapta Prt. (= flavicoma Sivh., Hmps., nec Warr.) (12 g). Postmedian line of foreAidiig generally anl-iohapta.
