AMERICAN MUTILLID.E. 267 



one-quarter longer than pedicel and first flagellum joint united ; middle segment 

 with a broad, central, smooth area, reaching from base two-thirds to the apex 

 the reticulation feeble and small ; first abdominal segment sparsely punctured! 

 rather narrow and convex apically, sides not narrowed anteriorly, from middle 

 straight; second dorsal apparently impunctate, second ventral sparsely punc- 

 tured ; segments not fringed ; wings subhyaliue, iridescent, nervures and stigma 

 yellowish. Length 5-7 mm. 



New Mexico : Las Cruces (Cockerell). Two specimens. 



149. ]VIutiIla hyalina Blake. 



Aftama hyalina Blake, Tr. Am. Ent. Soc. iii, 263, % . 1871. 

 Agama minuta Blake, ibid, iv, 76, %, 1872. 

 Photopsis minuta Blake, ibid, xiii, 272, % , 1886. 

 Photopsis hyalina Blake, ibid, xiii, 274, % , 1886. 



Texas. There seems to be no specific difference between hyalina 

 and viinuta. The hitter averages smaller in size. 



150. JVIutilla sarpedon n. sp. 



^. -Reddish castaneou.s, clothed with whitish pubescence; legs and flagellum 

 blackish; head at most as wide as thorax, strongly punctured, rather square 

 behind eyes; space between hind ocelli less than that between them and eyes- 

 antennae shorter than head and thorax united, first joint of flagellum nearfy as 

 long as second, the scape nearly twice as long as the pedicel and first flagellum 

 joint united; thorax strongly punctured, especially the middle segment which 

 unhke most species of the group, is not reticulate, unless the strong punctures' 

 with which it is covered, may be said to form a reticulation, at the base medially 

 are two elongate, parallel, smooth areas: first segment short and broad, .si.arselV 

 punctured, practically sessile with second ; second segment more stron-lv punc 

 tured, especially beneath ; segments fringed with a white pubescence,^which is 

 more evident when viewed laterally; wings subhyaline. the anteriors crossed by 

 a broad fuscous cloud between middle and apex, nervures dark, stigma black 

 Length 6-10 mm. 



Texas. Eleven specimens. I found these confused with 31. 

 danaus, to which it is only superficially similar. 



151. Jllutilla thainyras n. sp. 



V-Black, clothed with a thin, pale pubescence; legs browner; head rounded 

 behind; space between hind ocelli about equal to that between them and eyes • 

 antennae shorter than head and thorax, the first joint of flagellum considerably 

 shorter than second, the scape twice as long as pedicel and first flagellum joint- 

 thorax strongly punctured ; middle segment covered with large, deep punctures' 

 with two elongate, parallel, smooth, basal areas ; first abdominal segment sparsely 

 punctured, tolerably sessile with second, comparatively narrowly than in hyalina 

 or mrpedon: second dorsal sparsely punctured medially, at the sides and on 

 second ventral strongly punctured; segments not fringed; wings subhyaliue 

 slightly fuscous, nervures dark, stigma black. Length 5i mm. 



Texas. One specimen.
