128 PTYCHOPODA. By L. B. Pkout. 



perhaps slightly narrower, at least in the ^. Abdomen in cJ long, but this is almost equally the case in 

 biselata. Vertex of head brownish, concolorous with wings, collar scarcely darker; in biselata the vertex is 

 pale, the collar much darker. Both wings with discal dot well developed, first line and median shade weak 

 or obsolete, postmedian sometimes better developed, on an average slightly more sinuous and dentate than 

 in biselata; distal area not or inappreciably darkened; dots on fringe usually quite weak. Under surface 

 also a little more brownish than in biselata, especially the hindwing; markings usually rather weak. Some 

 of the distinctions given appear, however, to be somewhat inconstant, or at least somewhat intermediate 

 forms seem to occur in Central China, so that it is not altogether impossible that future investigations will 

 lauta. result in sinking invalida as another race of biselata. — ab. lauta Warr. is an unimportant aberration in 

 which both lines are strongly marked with black dots on the veins, the marginal dots also stronger than in 

 the type. — Pt. invalida is widely distributed in Japan May-early July and again in September, the second- 

 brood specimens and some others (especially $$) very small; ? Central China, June — July. 



perpulverea. Pt. perpulverea i^mpsw. (7 b). Dull flesh-colour closely irrorated with olivaceous brown; the lines rather 



weak, formed by accumulation of the brown scales; first line (present on forewing) wavy or subdentate, a 

 distinct distally-directed tooth observable on the second submedian; cell-spot of forewing large, elongate, 

 slightly oblique; postmedian line fine, wavy, bent near costal margin, slightly incurved between the radials 

 and more decidedly posteriorly; weak traces of a median shade between cell-spot and posterior margin; 

 fringe dark-spotted at base. Hindwing with the discal spot smaller and less black. Under surface rather 

 p?ier and more glossy, almost unmarked, forewing with a vague dark discal spot. Kashmir: Gooraise, the 

 type $ (taken in June) from the Leech collection, at present unique. In the absence of the ^ and of very 

 obvious affinity with any other known I am quite uncertain where to place this species, which is perhaps 

 Indo-Australian rather than Palearctic. It bears some slight resemblance to some $$ of invalida, but is 

 more Eupitheciid in aspect, on account of the rather thick scaling, somewhat elongate forewing and especially the 

 large discal spot of the forewing; the tone of colour is not altogether dissimilar to that of Eupithecia expal- 

 lidata Guen., though rather duller and less glossy. 



trlgeminafa. Pt. trigeminata Haw. (= scutularia part. Hbn. = reversata Tr. = bisetaria Dup. nee bisetata Rott). 



(4f). Somewhat similar to biselata, with which it wa.s sometimes confused by the early entomologists. Ground- 

 colour in the fringes very weak; the dark distal markings on the contrary brighter and sharper, of a more 

 chocolate-brown tone; costal margin dark from the base nearly to the first line; first and median lines weak 

 or obsolescent, but starting (or at least the former) from dark costal spots; the dark proximal shading of the 

 subterminal consists of paired spots, somewhat as in dimidiata but larger and sharper and with a strong 

 confluent pair at the costal margin; distal dark shading of subterminal almost wanting. Hindwing with the 

 paired spots smaller and weaker. It may also be remarked that the median shade of the forewing, when 

 developed, is differently placed from that of biselata, being proximal to the cell-spot or occasionally crossing 

 it. (J antennal ciliation as in biselata; hindleg similarly formed but with the tufts less extremely developed. 

 Egg oval, with a large depression on the upper side; the entire surface with regular, somewhat hexagonal 

 pitting; pearly white when first laid. Larva nearly cylindrical, but somewhat carinated laterally, tapering 

 gradually from the 5th abdominal to the head; strongly rugose, segment-incisions deep; dull deep brown, 

 dorsal line faintly paler, margined at the ends of the segments with thick black streaks; an ill-defined V- 

 shaped dorsal pattern as far as the 5th abdominal much as in biselata, and an interrupted dark subdorsal; 

 6th abdominal with a whitish dorsal blotch; lateral ridge pale, interrupted at the incisions; ventral surface 

 dark brown; setae curved, of equal thickness thoughout, longer than in the allied species. The moth flies 

 in May and June and there is sometimes a partial second brood, particularly in captivity; but I have found 

 the larvae sometimes refuse to be accelerated in their growth even under the influence of increased 

 temperatures. Locally common in Central and Southern Europe (except a considerable part of the Iberian 

 Peninsula), Asia Minor and Transcaucasia. Its habits are similar to those of the preceding species. Not 

 infrequently found by day resting on the upper surface of leaves like Pt. rusticata. 



hispanaria. Pt. hispanaria Piing. sp. nov. (3i). Expanse 22 mm. Near trigeminata Haw., larger, forewing more 



elongate, pale brick-reddish, markings similar, but much weaker, band of postmedian spots more or less 

 obsolete, hindtibial hair-pencil not dark, hindtarsus longer. S. Spain, Murcia, Sierra d'Espuna, 4 (^^, 2 9?> 

 M. KoRB, end of June 1909. Our figure gives a true impression of the cj of this quite distinct species; the 

 only 9 before me is smaller. The colour is more reddish than in even the brightest invalida, which is 

 otherwise the most highly coloured species in this immediate vicinity. 



rosea- Pt. roseofasciata Chr. I have not seen this species, but it should be easy to recognize by the colo- 



iasciaia. nation. According to its author it belongs in the neighbourhood of biselata, and the figure shows some 



resemblance in shape and in the general arrangement of the markings, at the same time the ^ hindtibia 



has not the hair-tuft of biselata but is appressed-iscaled. The $ antenna is described as "filiform", thus it
