segments are loosely attached at one end and flare out to a more 

 or less degree, so that the structure on the whole is less neat 

 and compact than in palniaritm. The partition between the 

 cells is formed out of much larger leaf-segments than in the 

 latter species, and these segments are worked to a greater 

 degree into the side walls of the cells. In size each cell is 

 about 8 or 9 mm. long and 7 mm. in diameter. The pupal 

 cocoon in this species is dull brownish on the outside and 

 darker, shining or almost black within. 



Megachile fullawayi Cockerell. 



CJockerell, Ann. and Mag. Nat. Hist. (8), 14, p. 2, 1914. 



This species, which was described from Guam, was first 

 taken here December 14, 1919, in Alakiki Valley (Williams) 

 and thus practically within the city limits of Honolulu. It 

 has been collected further as follows : Manoa \ alley, January 

 1. 1920 (Williams); Makapuu Head, January 25, 1920 (Wil- 

 liams) ; Mokapu Point, August 29, 1920 (Swezey), and Manoa 

 Valley, January, 1921 (Ehrhorn), all these localities being on 

 the southeastern end of (Jahu. The bees were found by Mr. 

 Swezey at the flowers of Scaczola kociiigii, and by Mr. Ehrhorn 

 at those of Antigoiwii lepiopiis. Further observations on the 

 habits of this bee have not been made. 



This bee agrees perfectly with Dr. Cockerell's description, but 

 as the peculiar front tarsi of the male w^ere not mentioned, I sent 

 a male specimen to the U. S. National Museum and requested Mr. 

 Rohwer to compare it with the type of fuUazvayi. Mr. Rohwer 

 promptly complied with my request and wrote that: "The type 

 fullaivayi has the pubescence yellower and denser ; the dentation 

 of the apical segment deeper, more pronounced and with 

 narrower teeth ; has the pubescence on the fifth tergite longer 

 and denser; has the broad, inner tooth of the right mandible 

 oblique, wider and with a faint sulcus which makes a slight 

 apical indentation above the middle (in your specimen the 

 tooth of the right mandible is narrower, truncate and without 

 a sulcus). Otherwise I do not note any characters and if the 

 material which you have before you shows any variation it 

 might be well to hesitate before describing it as new. The
