272 PTYCHOGLENE; TUINA; METERYTHROSIA. By Dr. M. Drattdt. 
M. dissimilipennis Dogn. (35 g) extremely resembles the preceding. The orange colouring of the forewing 
is more extensive; the hindwings are black, in the costal-marginal half whitish, the hair in and below the cell 
yellow. Expanse of wings: 26 mm. Ecuador. 
58. Genus: Ptychoglene Fldr. 
Distinguished from the preceding genus by longer palpi, which are likewise porrect, projecting beyond 
the forehead and being densely scaled. Antennae rather short and stout; posterior tarsi with shorter spurs. On 
the forewing the venation is the same, only the uppermost subcostal vein anastomoses with the costal; the 
5th subcostal vein rises nearer to the margin than the third. On the hindwing the upper median and lower 
radial vein are petioled, the middle radial being absent, the upper one rising with the subcostal vein from the 
cell-angle or on a short footstalk. A small number of species coloured red and black, most strikingly resembling 
certain Syntomidae (t. 9 a) and Zygaenidae (t. 26 c), so that they are partly only discernible by the venation. 
P. pertunda Dr. (35 g). Body black with a red collar. Forewings scarlet with a black marginal area; 
the red colour extends at the costal margin as far as near the apex, from where it runs obliquely proximal to 
the upper radial and from there vertically to the proximal margin. Hindwing black, with a narrow, red stripe 
at the base of the costal margin. Expanse of wings: 30 mm. Mexico. 
P. xylophila Drc. (35 g) is the same, but the red colour runs from the apex of the forewing in 
an oblique line to the base of the proximal margin; the border between red and black is irregularly dentate. 
Expanse of wings: 24 to 28 mm. From Mexico, Guatemala, and Nicaragua. 
P. sanguineola Bsd. (35 g). A well known species with scarlet forewings distally bordered with black; 
the hindwings are of a lighter red. Collar black like in the following species. Expanse of wings: 30 mm. Mexico 
and Guatemala. 
P. aequalis Wkr. (= haematodes Dyar) (35 g) is like the preceding, but the hindwings are black 
with a red costal-marginal spot. Expanse of wings: 30 mm. Guatemala. 
P. phrada Drc. (= flammans Dyar) (35 g) resembles aequalis, but the red of the forewing extends 
to the proximal margin; the hindwing exhibits beside the large red costal-marginal spot a red submedian stripe. 
In the $ the black border is broader. Expanse of wings: 30 mm. Distributed from Arizona to Mexico. 
P. erythrophora Fldr. (35 h) is also like the preceding, but the proximal margin is much more 
broadly black; the red costal-marginal spot of the hindwing very narrow and small. Expanse of wings: 28 
to 30 mm. Mexico. 
P. coccinea H. Fdw. Head and thorax carmine, abdomen black, at the base red; antennae and palpal 
ends black. Forewing in the basal two thirds carmine, distally bluish-black with a dentate proximal border. 
Hindwing in the basal half red, distally black, likewise with a dentate border. Expanse of wings: 24 mm. 
Arizona. 
P. stenodora Dyar (35 h) is bluish-black on its body and wings, with a carmine longitudinal stripe 
on the forewing and hindwing. Expanse of wings: 28 mm. Mexico (Tehuacan, Puebla). 
P. tenuimargo Holl. (35 h). We reproduce here the figure of a butterfly from Holland’s ,,Moths- 
Book“, being distinguished from the other Ptychoglene by the narrowly margined forewings; described from 
Arizona; besides in Mexico. The figure with Holland is most singularly labelled as ,,Lycomorpha fulgens 
Edw.“ which we have figured on t. 26 c and with whicRythe species has probably been mixed up. 
59. Genus : Tuina Btlr. 
Separated from the preceding by the antennae being roughly scaled. On the forewings the uppermost 
subcostal vein does not anastomose with the costal; on the hindwing the pedicle of the upper median and lower 
radial vein is longer than in Ptychoglene. 
T. cingulata Wkr. (35 h) is deeply black on its body and wings; palpal base, shoulders, shoulder- 
covers, and base of forewings flesh-coloured. Expanse of wings: 38 mm. Mexico, Honduras, and Guatemala. 
60. Genus: Meterythrosia Hmys. 
Very much like the preceding, but with longer, porrect palpi. Veins of the forewings exactly like there. 
On the hindwing the upper median and lower radial vein is unpetioled, so is the upper radial and subcostal 
vein, both doming from the corresponding cell-angles. In the cell-end there is an elliptic scent-spot.
