MASON AND LEFROY. 179 



Summary. Of 92 insects taken by 3 birds, 4 are beneficial, 

 19 injurious, and 69 neutral. 



Podargi. Frogmouths. Insectivorous. F. I. Ill, 193. 



1097. Batrachostomus hodgsoni. Hodgson's Frogmouth. 

 Beetles. F. I. Ill, 195. 



The Swifts are, for the most part, resident in hill tracts, the 

 only two species occurring in the plains have already been noted. 

 They are presumably beneficial. 



The Night Jars are mostly found in the plains some extending 

 into hill tracts in the North- West. Two species only (macrurus 

 and indicus) bsing generally or locally distributed throughout the 

 plains. They are usually regarded as beneficial. They may pos- 

 sibly be so. 



The Frogmouths frequent low hill tracts not being found 

 West of Sikkim in the North. Of the same economic importance 

 as the Night- jars. 



TROGONES. 



TROGONID^:. 



Trogons. 



Harpactes. The Trogon flies out from time to time in 

 pursuit of insects, chiefly beetles, moths, or cicadas, but it will 

 occasionally feed on insects on the ground. Indian Trogons have 

 not been observed to eat fruit as some of the gorgeous American 

 forms do. F. I. Ill, 199. Sit on trees, darting off to catch a pass- 

 ing insect or to secure a tempting fruit. The Old World forms 

 seem to prefer an insect diet. E. B. C. N. H., 442. 



1100. H. fasciatus. Malabar Trogon. Various insects chief- 

 ly coleopterous. Layard says it feeds on Spiders, Mantidse, and 

 Goleoptera, Jerd. B. I. I, 202. Large Moth. B. N. H. S. J. X, 

 292. 



1101. H. erythrocephalus. Red-headed Trogon. Coleoptera 

 chiefly. Jerd. B. I. I., 203.
