60 THE CANADIAN ENTOMOLOGIST. 



shield-like patches, which have been so conspicuous in all the larvae I 

 have met with, seems to have been noticed by the Professor in the larvae he 

 describes. The specimens of the perfect insect I have in my cabinet are 

 rather smaller, and much darker, than the representation in Strecker's work. 



NOTES ON THREE SPECIES OF XYLOCOPA. 



• BY W. H. PATTON, WATERBURY, CONN. 



Xvlocopa micans Lepel. 



X. micans Lepel., Hym. ii., 208, $ ; Smith, Tr. Ent. Soc. Lond. 



1874, 297, $ $. 

 X. vidua Lepel., Hym. ii., 210, °. . 



X. purpurea Cress., Tr. Am. Ent. Soc, iv., 2S4, °. ; Smith, Tr. 

 Ent. Soc. Lond., 1874, 299, °. . 

 From Mr. L. Heiligbrodt I have received a specimen of X. purpurea, 

 and it agrees in all respects with the female of micans. Accompanying 

 this was a male, evidently of the same species. It agrees perfectly with 

 Smith's description of micans £ , presenting only a few slight characters 

 not mentioned by him. The length is eleven lines, the sides of the venter 

 are blue, the tibiae and the basal joint of the tarsi are more or less tes- 

 taceous beneath, and the intermediate and posterior tibiae and a part of 

 the basal joint of the posterior tarsi are clothed with fulvous pubescence. 

 Xvlocopa varipuncta, n. sp. 



°. . Length 13 lines. Black, with black pubescence; wings dark 

 brown, with brassy and coppery reflections ; flagellum beneath, except 

 basal joints, piceous. Clypeus with large sparse punctures, the clypeus 

 limited above by a smooth slightly elevated ridge ; a tubercle between the 

 antennae, a small pit behind each posterior ocellus ; base of the mandibles 

 with few punctures and not excavated, labrum with three uneven ridges 

 or tubercles. Disk of mesothorax and scutellum above without punc- 

 tures, scutellum truncate. Abdomen punctured, the apical margins of the 

 segments and the median line on segments three to five without punc- 

 tures ; the punctures on segments one and two finer and more numerous 

 than those on the following segments. 



Arizona. Two specimens (C. V. Riley). Related to the West Indian 

 X. mordax Smith. 



Xyi.ocopa fimbriata Fabr. A female specimen collected in the 

 Yosemite Valley, Cal., by Mr. F. V. McDonald, adds this species to the 

 fauna of the United States.
