NO. 1806. BEES IN THE NATIONAL MUSEUM. l.—COCKERELL. 645 



postscutellum with a short yellow band; band on fourth abdominal 

 segment notched but not interrupted; that on fifth divided into two 

 large spots; third ventral segment with two large yellow marks, 

 fourth with one. Especially characteristic of the species is the large, 

 smooth and shining yellow mark on each side of face. Structural char- 

 acters, not mentioned by Smith, are as follows: Mandibles simple; 

 third antennal joint shorter than fourth, though both are quite long; 

 tegulse rather large, well punctured; area of metathorax rugose 

 basally; wings long; h. n. going far basad of t. m.; second s. m. 

 receiving first r. n. before middle; abdomen very finely punctured; 

 crescentic apical patch rather large. The femora, tibias, and tarsi 

 are entirely red, except that the hind femora have a blackish streak 

 behind. The tubercles are prominent, yellow margined with red, and 

 the upper border of the prothorax is yellow, red at each side. There 

 is a very large red patch on the pleura. This is perhaps a distinct 

 species, but as it is evidently close to N. maculifrons, and I have not 

 been able to compare specimens ; I leave it for the present as a variety. 

 The abdomen, in its color and pattern, shows a strong superficial 

 resemblance to that of N. ruficornis Linnaeus, variety, from Jena; 

 but in the ruficornis the yellow spot on the third segment is sublateral 

 instead of lateral, and there is no yellow spot laterad of the band on 

 the fourth. In Schmiedeknecht's table of European species it runs 

 to 52, and runs out because the yellow spots on scutellum are sepa- 

 rated, and the hind tibial apical spinules are red. It runs nearest to 

 N. lineola Panzer, which it really does resemble to a considerable 

 extent.

NOMADA RUFICORNIS KOEBELEI, new subspecies. 



Female. — Length about 9 mm., not especially robust, ferrugmous, 

 marked with black and yellow, the yellow confined to the abdomen. 

 Head broad, ferruginous, including labrum and the simple mandibles; 

 a black band extends from each side of clypeus to middle of front, 

 which is broadly black; ocelli on a black patch, but a transverse red 

 band in front of them; eyes light red; antennae long, rather thick, 

 entirely ferruginous; third joint long, but shorter than the very long 

 fourth; fifth about as long as third; mesothorax and scutellum little 

 hairy, very densely punctured; mesothorax with three black bands, 

 the lateral ones partly evanescent; scutellum moderately elevated, 

 entirely red; area of metathorax large, triangular, plicate at base; 

 metathorax with a broad median black band, becoming greatly 

 enlarged below the area ; mesopleura red ; tegulae red, well punctured ; 

 wings with a broad dark apical margin; h. n. meeting t. m.; second
