278 E. T. CRESSON. 



Melissodes intorta, n. sp. 



%. — Black, clothed with a rather dense cinereous pubescence, short on 

 clypeus and labrum and on mesothorax, where it is slightly mixed with black; 

 antennae shorter than usual, scarcely reaching to scutellum, flagellum testace- 

 ous beneath; thorax deeply, rather coarsely punctured; mesothorax pos- 

 teriorly and scutellum very thinly pubescent, almost nude, shining; the pu- 

 bescence on metathorax and pleura long and pale; tegulee piceous; wings 

 hyaline, apical margin faintly dusky; tibiae and tarsi densely clothed with 

 short pale pubescence, yellowish on tarsi within ; abdomen elongate, subcon- 

 vex, shining, thinly pubescent with short pale glittering hairs which fringe 

 the submargins of the segments, more dense laterally, sparsely punctured, the 

 apical margin of the segments depressed, smooth, impunctured, and narrowly 

 edged with pale testaceous, first segment clothed at base and sides with a sub- 

 erect pale pubescence; apical segments armed laterally as in rivalis except 

 that the teeth on the sixth segment is longer and larger. Length .50 inch. 



Two specimens. (Belfrage.) Easily distinguished from the two 

 preceding species by the black clypeus, the short antennae, the paler 

 pubescence and absence of bands on the abdomen. 



Melissodes Belfragei, n. sp. 



<p. — Robust, black, clothed with a dense white pubescence, cinereous on 

 occiput and thorax above and short on clypeus which is rather coarsely and 

 con fluently punctured ; labrum covered with dense ochraceous hairs; mandi- 

 bles tinged with yellowish at tips; disk of mesothorax thinly pubescent and 

 sparsely punctured; tegulse fuscous; wings hyaline, faintly dusky at tips; 

 legs with pale ochraceous pubescence, that on tibiae and tarsi within yellowish 

 or brownish; abdomen broad, depressed, velvety-black, first segment thickly 

 clothed with a suberect cinereous pubescence, second, third and fourth seg- 

 ments each with a rather broad, even, continuous, subapical band of short, 

 dense, appressed, snow-white pubescence, their apical margins smooth and 

 polished, apical margins of two terminal segments with cinereous pubescence, 

 disk of apical segment broad and broadly rounded at apex ; ventral segments 

 fringed with long paie ochraceous pubescence. Length .53 inch. 



One specimen. (Coll. G-. W. Belfrage ) This lovely species is dis- 

 tinguished at once by the three beautiful, rather broad, snow-white 

 bands on abdomen. 



Melissodes intermedia, n. sp. 



9- — Short, robust, black; head thickly clothed with pale cinereous pubes- 

 cence, long on face and occiput on which latter it is ochraceous and slightly 

 mixed with black; clypeus almost nude, rather coarsely and confluently punc- 

 tured; labrum covered with dense ochraceous hairs; mandibles tinged with 

 yellowish at tips; thorax clothed with a very dense yellowish-ochraceous pu- 

 bescence, longer and pale on metathorax and pleura, shorter and thin on pos- 

 terior disk of mesothorax and scutellum where it is more or less mixed with 

 black; tegulae piceous; wings hyaline, dusky at apex ; legs clothed with pale 

 ochraceous pubescence, that on tips of four posterior tibiae and on all the tarsi 

 wilhin brownish; abdomen short, broad, subconvex, shining, closely and
