Criotettix spinilobus, Hancock. 
Spolia Zeylanica, vol. II., p. 129, Plate III, figs. 12-126, 1904. 
Besembling the preceding species, but slightly smaller, the 
vertex of head little wider and the pronotum above lightly tubercu- 
late. It lives on swampy ground. But one specimen was taken by 
Mr. Fletcher at Maskeliya, March 10, 1909. It has heretofore been 
recorded from Pundaluoya. 
Acanthalobus miliarius , Bolivar. 
Ann. Soc. Entom. Belgique, XXXI., p. 226, 1887. Figured by 
Hancock in Spolia Zeylanica , Plate II., figs. 8-8a, 1904. 
This species is larger than Criotettix; the spine arming the 
lateral lobe on each side of the body is directed obliquely backward, 
and the vertex is broader between the eyes. It lives in rice fields 
and along the banks of streams. Two examples were taken : one at 
Colombo, October, 1907 ; the other came to light at Galle, Novem¬ 
ber 11, 1907. It has previously been reported from Peradeniya, 
Kandy, and Pundaluoya. 
Loxilobus rugosus, Hancock. 
Spolia Zeylanica , vol. II., p. 135, Plate III., figs. 17-176, 1904. 
A small short-wing species without lateral thoracic spines. It 
lives on grass lands and on swampy ground. One example was 
taken by Mr. Fletcher at Weligama, January 16, 1908. It has 
heretofore been recorded from Pundaluoya. 
Systolederus greeni, Bolivar. 
Ann. Soc. Entom., France, LXX., p. 584, 1902. Figured by 
Hancock in Spolia Zeylanica , vol. II., Plate II., figs. 9-96, 1904. 
A species readily recognized by the elevated closely proximated 
eyes, which are also strongly globose in profile view. It often 
frequents hot dry rocks away from the water, and is very active on 
the wing. At Madulsima, May 13, 1908, Mr. Fletcher writes that a 
small rocky-bedded stream contained a number of these insects, 
4 ‘which skipped nimbly over the rocks well clear of the water.” Three 
days later, on May 16, he found on visiting a small hillside stream 
a number of these insects, which occurred commonly on the bare 
surfaces of the dark rocks in the sunshine. Again, on May 20, he 
mentions : “In the forenoon went along the lower road out to the 
waterfall and took a number of small Tettigids.” I have identified 
these insects as Systolederus greeni and Criotettix tricarinatus. Later 
on in the season, August 12, this species occurred on damp rocks 
near a small stream, now nearly dry; here it was again found in 
company with the above species at a small pool by the pathside. 
Again, referring to this species, on August 16, he says : “ In the 
morning went a short distance along the lower road and took a few
