Abdomen coarsely, closely and deeply punctate. 



Legs rather slender, strongly, closely punctate, tibiae narrowly sinuate. 

 Length 3.2 mm.; width 1.5 mm. 



Described from four specimens (male and female), of which 

 the type and two paratypes are deposited in the U. S. Nat. 

 Mus., No. 10039. Bred from the roots of Monarda citriodora 

 at Dallas, Texas. On June 26, 1906, the roots of every plant 

 were full of larvae of this species ; the first pupa was found 

 October ist, although at the same time adults were found. 

 Larvae were found as late as October 4th, pupae October i2th, 

 and adults October 2oth. The plants are out of season by 

 July 3oth, but the weevils remain in the roots and evidently 

 hibernate as adults in their cells of frass. 



Baris cimeipennis Casey. This species breeds in the roots of 

 Helenium tenuifolium at Dallas, Texas. On September 17, 

 1906, the writer found in the cells in the roots 7 larvae, 6 

 pupae, 13 adults and 5 parasites. 



ORTHORIS Lee. 



Orthoris cylindrifer Casey. Like O. crotchii, this weevil 

 attacks Mentzelia, but not the same species nor in the same 

 manner. It was found (by the writer) to breed in the stems 

 and roots of Mentzelia oligosperma, a plant copiously armed 

 with adhesive hairs which occurs mainly on the sides of rail- 

 road embankments at Dallas, Texas. The larvae commence 

 attack in the outer parts of the stem, burrowing downward 

 toward the tuberous roots. The attachment of the stem to the 

 root is feeble, and after the larvae have entered the latter, the 

 stem breaks at the slightest touch. In the tuber the larvae 

 burrow about two inches and pupate. The first larvae were 

 found June 26th, adults having been captured on the plants 

 June 1 8th; larvae and pupae were found until August 7th. 

 The first adult was found in its cell of frass July 25th, and one 

 was found October 4th, probably expecting to hibernate thus. 



Group ZYGOBARI. 



In studying the weevils which attack the berries of Xaut/io- 

 xyluin, two new species were found belonging in the /ygobaris 

 group of Barini. The proper location of these may be had by
