cala. 
52. Genus: Cytocanis Hmps. 
Tongue well developed; frons with a large horny prominence with raised rim, the lower edge 
produced to form a beak-shaped process; palpi slender, short, porrect, the second segment scaled, the third 
slender and pointed; antennae of lamellate, simple; thorax and abdomen without crests; tibiae smooth; 
fore tarsi with shortened segments, and large ungues; forewing with costa straight, apex rectangular, 
termen evenly curved; neuration normal. Type 0. denticulosa Walk. 
This genus, like the last, contains only one species. 
C. denticulosa Walk. (20 a). Forewing reddish brown irrorated with white; the lines white, slen¬ 
der; subbasal line short; inner line oblique from costa to below cell, then angled inwards on vein 1; 
outer bent outwards below costa, then waved, and incurved below 4; subterminal line regularly and strongly 
dentate to termen; a white line just before termen; fringe mixed, white and red brown; orbicular 
and reniform stigmata with fine white edges, the former small and round; hindwing pale suffused with 
pale rufous, a white dentate subterminal line as in forewing. A south Indian insect, occurring in Bom¬ 
bay and Madras. . s 
53. Genus: ■>.V rzela Walk. 
Tongue well developed; frons smooth; palpi upturned, rather long, the second segment moderate¬ 
ly scaled, the third smooth and longer than usual; thorax and abdomen smoothly scaled, without crests; 
tibiae fringed with hair; neuration normal. Type D. plagiata Walk. 
Sect. 1. Antennae of bipectin ate to beyond middle. 
D. bosca Swinh. (20 a). Fore wing redbrown with a grey tinge and some dark dusting; inner 
and outer lines dark but indistinct, double; the inner obliquely curved, and faintly waved; the outer 
excurved to vein 6. incurved at cell fold, then oblique and wavy, followed by an oblique black spot be¬ 
tween veins 6 and 7; subterminal line minutely waved and very indistinct; median shade oblique above 
middle, vertical below; stigmata unrepresented; a row of conspicuous black dots just before termen; 
fringe fuscous; hindwing fuscous; fringe with pale line at base. Found in Burma and Borneo. 
D. increnulata spec. nov. (20 a). Forewing fawn grey, unspeckled; crossed by three oblique, slightly 
excurved, parallel brown lines, inner, median, and outer, all blackish at costa; the outer runs obliquely 
outwards to vein 6, along which it is shortly deflected basewards, then runs parallel to the median 
line; beyond it on costa a dark brown blotch, finely pale-edged, indented on each side below middle, 
the part below the indentation black; a subterminal row of black dots; fringe concolorous; a faint 
dark cell spot; hindwing brownish fuscous; fringe brown with paler tips; underside darker, shining brown; 
lines indicated only on costa of forewing; marked across hindwing, which shows a dark cellspot; tho¬ 
rax and patagia like forewing; dorsum like hindwing; frons, antennae, and outer side of palpi and forelegs 
blackish; pectus, venter, and legs internally paler; the legs externally fuscous. I $ from Minbu, Burma, 
31 mm. in expanse; very close to bosca Swinh., in which all the three lines are crenulate. Type in 
the Tring Museum. 
D. tumidimacula spec. nov. (20 a). Forewing larger and paler than that of increnulata; the three 
lines oblique, but not excurved nor parallel; the inner indented on median vein; the median indented in cell, 
otherwise straight; the outer indented beyond cell, then excurved; the costal blotch twice as broad 
as in increnulata, with rounded outline; neither edge indented, but the outer incurved and projecting 
at vein 7; a subterminal row of black dots; hindwing fuscous, paler than in increnulata, with the 
fringe concolorous; underside as in increnulata; head, palpi, thorax, and abdomen like forewing; pectus, 
venter, and legs paler. 1 $ from Gunong ljau, Malay Peninsula, March 1898 (Butler), expanding 33 mm. 
Type in the Tring Museum. The position of this and the preceding species is doubtful in the absence of the 
Sect. II. Antennae of $ strongly serrate to middle, with long curved 
sessile fascicles of cilia.
