3G4 ^Ir. T. D. A. Cockerell — Descriptions and 



the base yellow ; hair of thorax above pale fulvous; most of 

 mesothorax and scutelluiu bare, shininj^, with sparse but 

 distinct punctures. Wings shorter, faintly dusky, not milky ; 

 stiojma and nervures fuscous, second submarginal cell less 

 produced at lower inner corner. Claw-joints pale yellowish 

 (not bright feiTuginous) ; abdominal hair-bands more dense 

 and compact and fulvous; punctures of second segment 

 closer and liner; lateral teeth of last segment triangular, not 

 sharp and pointed. Tiie third antennal joint, except on upper 

 t-ide, is only about as long as second. 



Hab. Arizona (no other particulars known). 



In the Cresson collection. 



Melissodes agilis semiar/Uis, subsp. n. 



cJ . — Length 10-11 mm. 



Size and appearance of typical agilis (cotype from Texas 

 compared), but labrum black and mandibles without a yellow 

 si)Ot at base. The nervures are darker and redder, the 

 mesothorax is more shiny, and the red above the testaceous 

 hind margins of the abdominal segments is very evident. 

 From the subagilis form it is easily known by its larger sij^e, 

 •with the face less narrowed below. The middle and hind 

 tarsi and the tegulse vary from dark ferruginous to black. 

 Eyes light green. 



Hab. Fedor, Texas, May 29 (type) ; also May 25 and 

 Oct. 22 [Birkmann). 



Melissodes petulciformis, sp. n. 



9 . — Length about 15 mm. 



Runs in my tables to M. petulca, Cress., to which it has 

 the closest possible superficial resemblance, but on close 

 examination it is seen to differ as follows : — Somewhat larger ; 

 hair of labrum white (yellow in petulca) ; fuscous patch on 

 thorax not nearly reaching tegulse (practically reaching 

 tcguUe in pjetulca). Wings not so dark ; second submarginal 

 cell hardly more than half size of first (little smaller than 

 first in petulca) ; first r. n. meeting second t.-c. (entering 

 second s.m a considerable distance from the end in petulca) ; 

 b. n. falling some distance short of t.-m, (meeting t.-m. 

 in petulca). Abdomen finely and closely punctured, the 

 punctures on the bare part of second and third seg- 

 ments very distinct (these parts practically impunctate in 

 petulca) ; the apical bands of yellowish-white tomentum 

 on segments 2 to 4 broad and even, not broadened in the 

 middle, the black part of 3 and 4 scarcely wider than the
