as in the Curculionidae. Another characteristic is that the femora and tibiae of the 

 posterior pair, being directed in the same manner, are completely covered by the 

 wings. The head and beak are elongate and provided with setigerous tubercles 

 as follows: One pair between the eyes at base, one pair immediately behind eyes, 

 two tiny pairs between eyes, and two pairs on beak; the posterior pair being close 

 to the eyes, and the anterior behind the middle. The antennae are roughly tuber- 

 culate. 



The prothorax is margined anteriorly by four pairs of setigerous tubercles and has 

 one pair of discal setae. The mesothorax has two pairs of lar-ge setigerous tubercles 

 and a lateral pair of tiny setae. The femora bear two or three setae. The knees of 

 the posterior femora are visible dorsal ly only. 



The mesothorax bears three pairs of small setae between the bases of the elytra. 

 The metathorax is provided with two rows of setae on tiny tubercles, the anterior row 

 having two pairs and the posterior row six pairs. The abdominal segments have 

 dorsally five pairs of setigerous tubercles near the posterior margin, a pair of tiny 

 setae near the middle of the segment, and lateral setigerous tubercles. 



The ninth segment is provided with two large curved processes. The tenth seg- 

 ment is ventral to the ninth. 



Cylas turcipennis Boheman (1833) (PI. 31, B) 



Cylcs turcipenfiis 'Bohew.a.B, 1833, f« Schonherr, Gen. etSpec. Cure. v. i. p. 369-370. 



The brief preliminary diagnosis of the species presented by Boheman 

 is as follows : 



Elongatus, viridi-coerulescens, nitidus, antennis thorace pedibusque rufis, capite 

 cruciatim impresso, rostro punctulato, elytris modice convexis, subtiliter striato- 

 punctatis. Habitat in Java, in India orientali. 



The following dimensions are included in the detailed description: Length 3 lines 

 (6 mm.); antennae as long as thorax and head; club of male antenna longer than pre- 

 ceding joints; beak not longer than head; elytra twice as wide as thorax at base, and 

 twice longer than wide. The color description is as follows: Head obscurely viridi- 

 cceruleous; beak almost black; antennae rufo-ferruginous; thorax shining rufous; 

 elytra coerulescent-virescent; thorax beneath rufous, remainder of body beneath 

 coeruleo-virescent; legs rufous; tarsi beneath fulvous, spongy; female with femora 

 in middle annulate virescent. 



Two specimens from Palembang, Sumatra, collected by Mr. M. Knappert, 

 are here considered as this species. They differ only in having the beak 

 slightly longer than the head, and a statement to th\s effect might have 

 been made if the description had been based on examination with a low- 

 power lens. Two other specimens are at hand from Bay Laguna Prov- 

 ince, Philippine Islands, collected by Mr. P. L. Stangl. A part of a 

 body of a weevil from Guatemala, collected by Mr. D. G. Eisen, is also 

 undoubtedly this species. Pascoe records the species from Sarawak, 

 Java, and India. 

 Cylas femoralis Faust (1898). (PI. 31, F)

This species was collected by Mr. Rolla P. Currie at Mount Coffee, Liberia, 

 in February to April, 1897, and he has informed the writer that it was a 

 serious sweet-potato pest in that country. It is described from Kamerun. 

 In the Manual of Dangerous Insects ^ this species was referred to as 

 C. brunneus by mistake.
