Abstract
This paper reports the species richness and abundance of true dung beetles (Family Scarabaeidae: subfamily Scarabaeinae) in the Wasgomuwa National Park, Sri Lanka. This survey was conducted during the prolonged dry season using active and passive methods of sampling and revealed the presence of 25 species (637 individuals), including one endemic, Onthophagus martialis, representing eight genera. This finding is interesting as it suggests the possibility that this forest is equally as rich in dung beetles as forests of the wet zone reported by others. There was considerable disparity in abundance among the genera and species. The best represented genus was Onthophagus with a total of 16 species, whilst the most common species, with 159 individuals, was O. pygmaeus. All dung beetle species were unevenly distributed within the park. The information generated on this ecologically important group can be used to determine the true conservation value of the dry zone protected areas.

Abstract
A new scorpion species of the genus Buthoscorpio Werner, 1936 is described from Chinnar Wildlife Sanctuary, Idukki District, Kerala, India. The new species, Buthoscorpio chinnarensis can be distingued from the other congeners by having (1) carapace with scattered granulation on lateral portions; (2) median eyes situated anteriorly in the ratio 1:2; (3) prominent tubercles present at the basal portion of the pedipalp femur; (4) marginal lamellae of pectines composed of three pieces and middle lamellae comprises seven pieces of sclerites; (5) dorsal carinae present on metasomal segments III–V; (6) subaculear tubercle absent on telson; (7) Pectinal teeth count 14/16 (female paratypes with 17/17 and 16/17 respectively); (8) Metasomal segments I–IV wider than long, segment V longer than wide; (9) arrangement of lateral eyes. After the description of this new species, the total number of known species in the genus is raised to five; four in India and one in Sri Lanka.
