 Distribution of certain BiUbugs. — Ecology [Brooklyn, X. Y .], 

 ii, no. 3, July 1921, pp. 198-210, 1 fig. [Received 9th August 1922.] 



As a result of much injury to crops by billbugs, a study has been 

 made of North American species, and preliminary notes are gi^'en here 

 on the distribution and food-plants of several species not dealt with 

 in the author's previous bulletin [R.A.E., A, vii, 378]. The areas 

 examined were shortly to be reclaimed for agricultural purposes, so that 

 the natural habitat of the weevils could be ascertained and at the same 

 time valuable data secured for the prevention of losses to new crops. 

 Sphenophonis {Calendra) ludoviciantis, Chttn., one of the largest species, 

 is kno\vn as the chicken weevil, because chickens frequently pick up the 

 weevils, which thereupon fix their legs and claws into the bird's mouth 

 or throat so that they cannot be swallowed and may cause death. 

 Adults have been foimd in the winter in cells under timber or logs near 

 water. The knife-flag [Zizaniopsis miliacea) was found to be infested 

 to the extent of 90 per cent, with the larvae, which work at the bases 

 of the leaves at the root crown, pupation probably occurring normally 

 in the soil but sometimes within the plant. 



S. costicollis var. callosipennis, Chttn., was taken on a species of 

 Carex, probably C. lurida, m the larval stage, and has also been reared 

 on timoth}^ grass. Pupation was observed in the cut-off stalk of Carex ; 

 adults in cages were fed on wheat and various grasses. S. cariosus, 

 Oliv., was found infesting Cyperus erythrorhizos and Rhynchospora 

 corniculata growing near trees. Maize in close proximity was so 

 badly damaged by billbugs, partly this species, that the field was sown 

 to cowpeas. It has also been recorded as destroying rice in freshly 

 broken fallow land where the native food-plants had been destroyed. 

 S. idkei, Horn, was collected among the roots of bluegrass. 5. scoparws, 

 Horn, has been found destroying rice in the field, and has also been 

 taken on Carex sp. (probably- C. lurida), on cat-tail and one female on 

 maize. S. compressirosiris. Say, has been found in prairie land where the 

 predominating grass was Bouteloua, and also destroying maize in a field 

 sown after removal of the native food-plants. S. melanocephahis, F., 

 has been taken in small numbers on timothy, cat-tail and various food- 

 plants, and has been fed in cages on various grasses and on wheat stems. 



S. glyceriae, Chttn., and 5. glyceriae var. missouriensis , Chttn., were 

 found in numbers ovipositing on Glyceria septentrionalis (manna grass). 

 S. germari, Lee, was taken on flooded rice and was fed in cages on 

 timothy grass, Cyperus strigosus and maize.

 The capture of Leptinotarsa decemlineata in potato fields close to 

 Bordeaux is recorded.

 Among new species of the genus from the French Congo, Alcides 



gossypii, captured on cotton plants, is described.
