ferruginous; bare hind margin of second 

 nbd. segment reddish ; hair of two apical 

 segments chocolate-colour ; liair on iuuer 



side of b. j. dark fuscous M. intermediella, Ckll.

 fuscous ; bare hind margin of second seg- 

 ment black. Kyes greenish 3. 



3. Abdominal bands white ; hair on inner side 



of b. j. ferruginous M. hiimiliur, Ckll. 



Abdominal bands yellowish ; hair on inner 



side of b. j. rufo-fuscous M. humilior cfttalinemis 



{M. intennedieUa caldHnensis, Ckll.). 



4. Flagellum dark red beneath M. pecosel/a, Ckll. 



Flagellum bright red beneath .... {M. pecosella verbesinarum, Ckll.). 



For other distinguishing characters, see the original 

 descriptions. M. p. verbesinarum was described from a 

 single example, but I have another collected at Las Cruces, 

 N. M., Sept. 23, at flowers of hocoma Wrightii. 



Melissodes confusiformis , sp. n. 



? . — Length about 12 mm. 



The broad bands on abdominal segments 2 to 4 pale 

 ochraceous, that on 4 entire and covering margin, its upper 

 edge in median line produced to a blunt point ; band on 

 second segment broad like that on third and a little arched. 

 The hair on inner side of b. j. is fusco-ferrugiuous, or ferru- 

 ginous stained with black : it the insect is classed with those 

 liaving this hair ferruginous, it goes in my tables to M. gil~ 

 ensis, Ckll., which, in fact, it closely resembles ; if it is classed 

 Avith those having this hair black or fuscous, it runs to 

 M. nigrosignata, Ckll., but it is also closely similar to 

 M. covfusa, Cress., and M. griyidelicB, Ckll. {montana, 

 Cress., ?). It is best defined by comparing it with the 

 four species mentioned. From M. gilensis it differs by the 

 flatter and less robust abdomen ; the band on fourth segment 

 not nearly so broad (in gilensis it almost covers the segment) ; 

 the wings smaller and hyaline (strongly dusky in gilensis), 

 the b. n. falling short of t.-m. (meeting it in gilensis) ; the 

 shorter black hair of scutellum ; the shorter (very broad for 

 its length) head ; the yellowish (not green) eyes ; and a few 

 minor characters. From M. nigrosignata it differs by its 

 much less robust form, with conspicuously narrower abdo- 

 men ; yellower abdominal bands; pale ferruginous spurs; 

 liair on middle tarsi yellowish white above [i. e. out-ide).
