and inconspicuous bands of pale appressed hair ; apical plate 

 broad. 



In the table in ' Entomologist/ July 1902, p. 177, this 

 runs to M. personatella, from which it is readily separated by 

 its larger size, well-punctured mesothorax, &c. It also must 

 be compared with M.semitrisiis, Ckll., which it much resembles, 

 but from which it is easily distinguished by the black hair 

 on disk of abdomen above. The eyes are green ; the facial 

 quadrangle is about as broad as long; the lateral subapical 

 spines of abdomen are small. 



Hob. Mexico (Deppe) ; Berlin Museum, no. 1335. Un- 

 fortunately the exact locality is unknown to me. 



Specimens of Thygater viontezurna (Cresson) and Melissod^s 

 grindelice, Ckll., are also labelled " Mexico (Deppe)," but 

 they could hardly have been collected at the same place. 



Alelissodes atrifera sandiarum, subsp. n. 



^ . — Agreeing with the Mexican M. atrifera, Ckll., except 

 as follows : — A little less robust, the head conspicuously 

 smaller; eyes pale bluish green instead of yellowish green ; 

 tegulse darker ; vertex very shiny (dullish in atrifera) ; abdo- 

 men with very conspicuous apical or subapical hair-bands on 

 all segments except the first, these bands yellowish white. 



Known from M. personatella, Ckll., by the larger size, 

 second antennal joint shorter than third; mesothorax quite 

 closely punctured, with nearly the anterior half covered with 

 pale hair. 



Among the species of New Mexico it is easily distinguished 

 by the combination of black tegument of clypeus and labrum, 

 mandibles with no yellow spot, antennae long, and thorax 

 with much black hair above. 



Hab. Sandia Mountains, New Mexico, at flowers of Croton, 

 July 26, 1909 (J. R. Watson). 



Alelissodes colliciata, sp. n. 



£ . — Length about 12 mm. ; antennae about 9. 



Black, the clypeus, large spot on mandibles, and labrum 

 yellow; flagellum bright ferruginous beneath ; third antennal 

 joint much longer than second ; hair of head and thorax pale 

 yellowish, on thorax above bright orange-fulvous, without 

 any black ; abdomen with hair on first segment and base of 

 second yellowish, but the median bauds on second and 

 following segments (that on second failing in middle) glit- 

 tering white ; inconspicuous black or dark fuscous hair on the
