HEMIPTEUA— UOMOPTERA— CEKOOPl D.K. 335 



Specimen No. 208, tif^'iired on Piute 21, has been mislaid and was not 

 examined at the time when this description was drawn up. 



2. Palaphrodks obscura. 

 PI. 21, Fig. 18. 



This species differs from the preceding, to which it is most nearly allied, 

 mainly in the obscurity of its markings, which in general follow the position 

 of those in P. cincta, Unfortunately the most deeply marked specimen 

 was figured, and its color has been somewhat deepened on the plate, so that 

 the diffei'ences do not there clearly appear ; ordinarily, however, besides the 

 obscurity of the markings, the middle transverse stripe is also broadened, 

 and so, as it were, diffused (not at all the case in the individual figured), 

 and the subapical oblique stripe becomes a far broader, short, quadrate bar 

 on the costal margin. It appears to be ordinarily a smaller species than the 

 preceding, but one individual is nearly as large as the largest of that species.

3. Palaphrodes irregularis. 

 PI. 20, Figs. 2, 18 ; PI. 21, Figs. 0, 7. 



This species, with P. cincta the commonest of the genus, appears to 

 differ from it very decidedly in the form, extent, and position of the darker 

 markings beyond the basal ; they occupy, indeed, so much more room 

 where they are well developed as to cover more space than the lighter j^arts, 

 so that the tegmina might quite as well, or better, be regax'ded as dark with 

 light markings ; the median belt occupies on the costal margin precisely the 

 same position as in P. cincta, but in passing across the wing it immediately 

 and considerably expands, rarely, however, without being moi-e or less 

 broken and blotched with pale ; at the center of the wing its expansion 

 tends to break it up into two forks, and the commissural portion is highly 

 variable ; in general, however, the proximal fork is far more intense and 

 distinct than the distal, leaving between it and the basal patch of the teg- 

 mina an often well defined, constantly narrowing, transvei'se, white band, 

 broad on the costal margin, reduced neai'ly to nothing on the inner, and
