PSYCHE. 



whitish trianguhir markings on anterior eve- 

 margin, tlie lower one elongate and extended 

 in a line nearly to base of antennae; tliese 

 leave two larger transverse glabrous shining 

 black areas. Antennae and aiista grayish. 

 Facial depression silvery, base with blackish 

 lower border, the black of the latter descend- 

 ing in one specimen in a median line on the 

 closely approximated and soldered facial 

 ridges. Whole of sides of face, cheeks, oral 

 region, in fact all of head below antennae, 

 covered with a yellowish-white bloom and 

 clothed with whitish hairs, the oral region 

 especially hairy; two small black spots on 

 cheeks, one next lower margin of eye, and 

 tlie other well removed therefrom toward 

 oral slit. Dorsum of thorax and scutellum 

 grayish-black, short and finely black-hairy. 

 Whole under surface of thorax, with sides 

 of thorax, both above, below, and anterior to 

 wing bases, and continued completely around 

 edge of scutellum, thickly yellowish-white- 

 hairy ; three black spots on side of thorax, 

 the upper one hairy. Abdomen black, with 

 a bluisli or pnrplisli luster, rather thickly 

 clothed with short and fine black hairs; 

 inferior lateral edges with regions of grayish 

 bloom containing blackish spots, in one 

 S|>eL'imen continued faintly on sides of abdo- 

 men in places. Restoring the color of tlie 

 abdomen with chloroform shows this gray- 

 ish bloom, with the circular black spots, 

 to extend in both specimens upon sides of 

 abdomen and dorsum of last two segments, 

 and even in places on dorsum of second seg- 

 ment. Legs blackish, inferior surface with 

 more or less of a grayish bloom, especially 

 on femora and tibiae. Wings, tegulae, and 

 alulets fuscous or smoky, the alulets very 

 prominently approximated to sides of scu- 

 tellum when wings are closed over abdomen. 

 Described from two specimens bred from 

 larvae taken, Oct. 15, from Lepiis artemhiu 

 Bach., near Dona Ana, New Mexico, the 

 adults having appeared about the first of 

 Mav following. 



JVIy description of the larva in Psyche 

 shoiiUl be slightly changed. The so- 

 called "'short horny spurs" are better 

 characterized as " spin'-like plates," as 

 I later described them in Ins. Life (1. 

 c, 320). Mr. Austen is quite correct 

 in calling them " imbricated scales." 

 The length of the fully grown larva 

 is greater than given in Psyche. Alive 

 thev jiieasine as long as 30 mm., by 

 14 mm. wide; dead and contracted 

 in alcohol, they ineasure as long as 26 

 mm., bv 16.J mm. wide. 



The larva I described in Psyche as a 

 Dermatobia is doubtless to be referred 

 to Bngeria. The spines are arranged 

 in zones, as described by Austen, 

 though my specimens are little more 

 than half grown and show the spines 

 much less conspicuousl)'. They are 

 liirected backward, are hardly curved, 

 antl are confined to a little less than 

 anterior half of segment. I can see 

 no smaller spines on posterior margin 

 of segment, but the small bluntly-coni- 

 cal tubercles of rest of surface show in- 

 distinctly in places. The latter are 

 what caused me to fall into "the error 

 of describing the segments as sparsely 

 covered with short spines, since I mis- 

 took the indistinct tubercles for very 

 small spines just appearing. This mis- 

 take is easily made in young or half 

 grown larvae. 



Mr. Austen's species, Bogei-ia prin- 

 ccps, I have little doubt infests the jack- 

 rabbit {^Lepiis callotis Wagler) in 

 Sonora. It is very likely the same as 

 the New Mexico species.
