second segment almost smooth ; 5.5-8 mm. long. Glribodo's halictula 

 does not differ ; his description is as follows ( the notes in brackets are 

 mine) : '• Related to 0. hihiris Dahlb., but distinguished from it in the 

 following characters: antennte filiform, articles not swelling (varies in 

 hil'iris), posterior margin of pronotum and sides not abnormal (not ab- 

 normal in hil(iris), third segment of abdomen conspicuously narrower at 

 apex than at base (also decidedly the case in Mian's), anteapical series mod- 

 erately abrupt (small, but distinct in hibiris, this is probably what is 

 meant by abrupt), length of body 6 mm. Habitat, California." 



Gribodo has incorrectly determined hildris, for Dahlbom's description 

 reads : " metanoti anguli postico-laterales magni conici." 



Clirysis tola Aaron. 



Ckrysis Integra (name preoccupied) Cresson, Proc. Ent. Soc. Phila. iv, 306, 

 1865; Norton, Trans. Am. Ent. Soc. vii, 240. 

 Six specimens in the collection, including the type, all from Colorado j 

 color is emerald-green all over with brassy reflections and very little blue 5 

 head and thorax covered with comparatively long fuscous pubescence ; 

 head, thorax and lateral surface of abdomen with the larger punctures 

 sparse, the intermediate spaces filled up with close, fine punctures; 10-12 

 mm. long. The var. a. $ of Norton is the following species. The 

 name integra has been used by Fabricius (Syst. Ent. ii, 241) for a spe- 

 cies found in Africa. 



Chrysis cobaltiiia n. sp. 



Chri/sis inicgi-a var. a. ^ . Norton, Trans. Am. Ent. Soc. vii, 240. 

 Elegant blue with some green and very slight purple reflections: head with 

 dense fuscous pubescence, shorter and less dense on the thorax ; head and thorax 

 densely punctured, on the prothorax with some finer punctures between the larger 

 ones; punctures on abdomen less dense, those on the first and second segments 

 shallow, the larger ones sparse, and with separated finer punctures on the inter- 

 mediate spaces, those on the third segment contiguous, subequal; apical margin 

 of third segment very slightly sinuate in the middle, the lateral posterior corners 

 distinctly but slightly produced or lobed ; pits small, shallow, rather close, con- 

 tained in a shallow groove, which ends about midway on the lateral margin; 

 wings hyaline, the basal half infuscated, the radial cell darkest; tarsi fuscous; 

 9 mm. long. 9 . 



Massachusetts; one specimen. This is probably the typical specimen 

 of Norton's var. a. $ of integra. 



Chrysis lateri-dentata n. sp. — Rather dull, light green, with some 

 brassy reflections; head and thorax closely punctured, the punctures not large, 

 subequal; abdomen with the first and second segments densely punctured, the 

 larger ones separated, the spaces between them filled up with finer punctures of 

 several sizes; third segment with the punctures smaller, contiguous, subequal; 

 apical margin nearly straight, the lateral posterior corners each produced into a
