Longs Peak Inn, July 21. at flowers of Scdiun stenopetalum 

 (IT. P. Cockerel!) . Runs in the Rocky Mountain key (Bull. 

 i>4, Colo. Agr. Exper. Station) to 65, but is quite distinct from 

 .iV. libata, coloradcnsis or mcra. On account of the structure 

 of the antennae it falls near N. alpha Ckll., from which it is 

 easily known by the markings. 



MELECTIDAE. 

 Phileremus americanus Cress. H., 1 $. 



ANTHOPHORIDAE. 



Anthophora smithii Cress. L., 1 . This differs from the 

 New Mexico race (cardui Ckll.) by having the clypeus, etc., clear 

 white (cream-color in cardui), and the eyes purplish-gray (pale green 

 in cardui). 



Clisodon terminals Cress. L., 2 ?. T. S., 1 9 . L. P. T.. 

 1 9. 



Melissodes kelloggi n. sp. 



$. Length about 9 mm. Runs in my table of Melissodes (Trans. 

 Am. Ent. Soc.. xxxii, p. 76) to M . rii'alis Cress., but is smaller and 

 otherwise different. The general aspect is that of M. ayilis Cress., 

 but it is readily distinguished by the dark purplish or blue-green (not 

 pale green or pea-green) eyes, the entirely black labrum and base of 

 mandibles, the darker antennae (flagellum black above) and the dark 

 fuscous nervures. Compared with subayilis Ckll., it is at once dis- 

 tinguished by the color of eyes and antennae. The thorax has very 

 pale ochreous tinted hair, with no dark hairs on the dorsum. 



Longs Peak Inn, July 19 and 21 (T. D. A. and }\\ P. 

 Cockerel!). 5 $. Dedicated to Professor Vernon Kellogg, 

 in recent years distinguished for his great services to human- 

 ity, but long ago a keen collector and student of the insects 

 of the Long's Peak region.
