narrow hair bands, that on second interrupted in middle, and that 

 on first only present on sides ; second segment depressed hardly one- 

 third in middle. Apical plate broadly rounded at end. 



In the key this falls in a couplet with A. cressoni Icansensis, from 

 which it is separated by the brownish hind tibiae (stramineous in 

 Icansensis) . 



o 23 . Flagellum dark; area of metathorax not conspicuous as in A. moquiorum. 



ANDRENA LATISIGNA, new species. 



Placita, New Mexico. April 25, 1903. (T. D. A. and W. P. 

 Cockerell.) 



Male. — Length, 8 J mm. Black, the clypeus except two spots and 

 broad lateral marks filling space between clypeus and eye except a 

 small triangle just below each antennae, primrose yellow; tarsi and 

 greater part of hind tibiae ferruginous. Pubescence pale ocherous. 

 Head large and very broad. Process of labrum truncate. Antennae 

 dark; third joint nearly as long as next two together; the fourth 

 very short. Cheeks broad, hairy, dullish, not angled behind. Meso- 

 thorax and scutellum somewhat shiny, hardly punctured. Area of 

 metathorax roughened. Tegulae brown with testaceous margins. 

 Wings dusky hyaline, nervures and stigma clear ferruginous. Basal 

 nervure meeting transverse median. First recurrent nervure received 

 by second submarginal at or a little beyond middle. Abdomen with 

 very small but distinct punctures on the first three segments; hind 

 margins of second and following segments reddish, with rather incon- 

 spicuous grayish white hair bands, interrupted in middle of second. 

 Second segment in middle depressed about one-third. Apical plate 

 extremely narrow, slightly emarginate. 



This is easily known from A. bridwelli by the large lateral face- 

 marks, face-marks all light chrome yellow, and all tarsi red. 



In the key it falls next to A. miserabilis. 



o 22 . Lateral face-marks not filling space between clypeus and eye. 

 a 24 . Abdomen blue; first recurrent nervure joining second submarginal cell before 

 middle (not so in bruneri and lawrencei, which are not females of this group). 

 a 25 . Hair of thorax above light ochreous. 



ANDRENA LARAMIENSIS, new species. 



Laramie, Wyoming. "6, 9, 93.' ' 



From collection of Prof. L. Bruner but collected by Professor 

 BufTum. 



Male. — Length about 10 mm. Head, thorax, and legs black, the 

 small joints of tarsi dark reddish. Abdomen shining, dark greenish 

 blue, apical margin of segments obscurely reddish. Clypeus except 

 lower edge and two spots and rather large lateral marks not reaching
