218 HYMENOPTERA. 



white, From 5". riibripes Spin, it is easily known by the pallid 

 tegulae, wherein it resembles S. 7-uHcornis Sich. and S. rufi- 

 thorax Mor. There is much resemblance to ^, desertus Nurse, 

 but that has the abdomen very finely and closely punctured. 

 Spliecocles lautipeniiis Ckll. 



This species was described from Boulder County, Colo. 

 Its range is greatly extended by a couple of males taken by 

 Mr. W. M. Mann at Pullman, Washington State, Sept. 13, 

 1908. 

 Sphecodes Iiesperelliis Ckll. 



Two males from Pullman, Wash., Aug. 2, 1908 ( W. M.

 Sphecodes arroyanus Ckll. 



This species has been known from New Mexico and Colo- 

 rado ; its range is greatly extended by a female taken by 

 Mr. J. B. Wallis at Lethbridge, Alberta, July 4, 1909. It 

 differs from southern examples in having the mandibles dark 

 red in the middle. It might be confused with 5. clematidis 

 Rob., but is easily separated by the large broad head.

 the type of Andre^ia exagens Walker, 1860, from Ceylon, and 

 as was expected, finds it to be a No7nia, It is about 5^ to 6 

 mm. long. It appears to be related to N. basipicta Wickwar, 

 also found in Ceylon. 

 Noinia iiiuscateiisis Ckll. 



This species, described from Muscat, Arabia, must be 

 added to the fauna of India, having been taken by Mr. E. 

 Comber at Karachi. Mr. Meade-Waldo informs me that it 

 was known to F. Smith, who gave it a manuscript name. 

 One female is labelled "Hab R., Karachi, Sept. 1909." The 

 male, hitherto undescribed, has also been taken at Karachi 

 by Mr. Comber : one has the date October, 1909. It has the 

 following distinctive characters : 



6^ . Tegument of thorax black, with the tubercles, the lateral scutel- 

 lar lobes and the greater part of the postscutellar process ferruginous; 

 antennae entirely ferruginous, of a darker shade above ; hair of face
