634 Mr. Distan@® descriptions of new specics 
compared with L. tuberosa, Sign., as having the opercula 
‘**muinus longe producta.” In specimens of L. tuberosa, 
in my own collection, the opercula are short, reaching 
the base of the second abdominal segment, whilst in 
L. pryert they are much more elongated, and attain in 
length to the middle of that segment. 
Dundubia radha, n. 8. 
3. Body above pale castaneous. Head with the 
area of the ocelli black. Pronotum with the lateral and 
posterior margins, and a very narrow anterior margin, 
ochraceous; the last is inwardly margined with two 
small transverse linear black spots, and the posterior 
margin has also a very narrow discal inner border of the 
same colour. Mesonotum with a large central obconical 
spot on anterior margin, with a very indistinct central 
line, and with the lateral borders black, outwardly mar- 
gined with ochraceous ; five indistinct black basal spots, 
three within the anterior angle of the cruciform eleva- 
tion, and one on each side of the same. Abdomen rather 
darker in colour, with the segmental sutures pitchy. 
Under side of the body concolorous; opercula dull 
ochraceous. ‘Tegmina and wings pale hyaline ; tegmina 
with the costal membrane and claval area dull ochraceous; 
wings with the base narrowly of the same colour. The 
body is very elongated ; the head, including eyes, a little 
narrower than base of pronotum ; the face is prominently 
convex, faintly longitudinally sulcated, and transversely 
striated ; the rostrum reaches the middle of the posterior 
coxe ; the opercula are very long, reaching the penulti- 
mate abdominal segment ; they are suddenly narrowed 
on first abdominal segment, and then gradually widened 
and rounded on each side, the maximum width being at 
junction of second and third abdominal segments, from 
whence they are gradually narrowed to apex, which is 
obtusely rounded. Long. 53 mm. Exp. tegm. 124 mm.

This species is allied to D. mannifera, from which it 
differs by the much broader head, attenuated apices of 
the opercula, and its much larger size. In superficial 
appearance it bears a strong affinity to the genus 
Cosmopsaltria,
