Campylarchis acuta, new species 



Figures 129-130, 471, 471a, 577 



Male, 23 mm. Head and thorax pale ochreous, slightly suffused 

 with tawny. Palpus fuscous tawny, dusted ^\dth bro\\Ti, dusting 

 becoming less dense towards apex. Abdomen pale ochreous. 



Forewing elongate, dilated, pointed, costa curved at extremities, 

 straight in middle, apex pointed and produced, termen sinuate, 

 concave above, rounded beneath. Pale ochreous (worn), markings 

 tawny fuscous and purplish brown. Indication of an inverted- 

 trapezoidal patch on middle of costa reaching to middle of cell; a 

 light tawny suffusion beyond cell; a bright tawny suffused marginal 

 streak along termen and in tornus, from apex to dorsum; a spot of 

 deep purple sparse dusting opposite middle of termen. Ciha pure 

 white with a brown apical third (imperfect) . 



Hind wing and cilia pale greyish. 



Male genitaha sclerotized. Tegumen short, strongly rounded, 

 with juxta forming a complete circle. Uncus indicated by a small 

 bicuspid prominence, gnathos, bj^ a short process at each side. Saccus 

 long, narrowed, about 3X as long as tegumen. Sacculus strong, 

 semioval, top with two rounded processes. Cucullus short, rounded, 

 bristly. External lobe of valva triangular, upper edge concave, 

 point acute, a rounded knob at base apparently forming an articula- 

 tion with sacculus. Anellus lobes moderate, slender, bristly. Aede-

Material examined: Luzon, Benguet Subprov., Pauai, 7000 ft., 

 Haights Place, 17.XI.1912 (A.E. Wileman), 1 d', holotype, genit.

Peragrarchis DiakonofiF, 1959 



Peragrarchis Diakonoff, 1959, Bull. British Mus. Nat. Hist., Ent. ser., vol. 8, p. 

 124, figs. 1, 2, pi. 5, fig. 7 (d-). 



Type species: Meridarchis rodea Diakonoff, 1950 (New Guinea). 



Now that the status of several earlier-described species of Meri- 

 darchis is clarified in Clarke's monograph (1963, vol. 4), the following 

 two species may be transferred from Meridarchis to the present genus. 



Peragrarchis pelograpta (Meyrick, 1929), new combination
