THE CANADIAN ENTOMOLOGIST. 191 



abdomen, light reddish brown, smoky, with pale longitudinal bands ; 

 sector trifid, four transversals in the cell, and one in the space below 

 (after the figure). Abdomen light rufous brown, smooth above and below, 

 somewhat hairy besides ; appendages two-jointed, hairy, the apical one 

 thinner, longer ; the apical ventral segment below is to the left strongly 

 truncated and excavated ; in consequence of this asymmetry the basal 

 joint of the left appendage is very short, broad, flattened and somewhat 

 abortive. ]\Ir. Lucas found the same asymmetry in each of the dozen of 

 specimens collected by him. To decide the sex of his specimens he cut 

 open the abdomen of several of them, and found all to be females. 



Wingless larva (after Lucas) : Length of body 13 mill; breadth 2 

 mill. Rufo-fuscous ; head ovoid, smooth, sparingly villous, above some- 

 what depressed ; eyes reniform, dark fuscous, not prominent ; antennae 

 rufo-yellowish, with yellowish hairs, as long as head and prothorax (after 

 the figure), iS-jointed, joints about alike, successively shorter, the last as 

 long as the first, but thinner, rounded on tip ; palpi yellowish. Prothorax 

 very short, anteriorly with a transversal sulcus ; mesothorax twice longer, 

 anteriorly with a much deeper transversal sulcus ; base narrower ; meta- 

 thorax very short ; no traces of wings (after the figure). Legs (after fig.) 

 yellowish, the basal joint of the tarsi of fore legs dark fuscous, with the 

 usual dilatations. Abdomen with nine dorsal segments ; appendages 

 rufous, the basal joint a little longer ; the figure of the end of abdomen 

 shows the last dorsal segment triangular. 



Habitat. — Around Alger, especially near Milah and Constantine, the 

 winged specimens living gregariously in sandy places in June on the stems 

 of a dry Scilla maritima ; very agile; 12 specimens collected. The larva 

 is not very rare around Alger during the winter, living in small silken tun- 

 nels under humid stones ; the larva is carnivorous and very agile.* Mr. 

 Lucas, in his paper, Ann. Soc. Entom. Fr. 1859, 1. c, states that he col- 

 lected, April, 1850, at Medeah and Bogar, province Alger, some larvae 

 which were placed in boxes, but by chance forgotten till 1S58. He found 



* McLachlan, Embid., p. 376, says rightly: Ilagen, Stett. Zeit. 1849, p. 56, 

 said that nothing had then been recorded as to the habits. He (McLachl.) has over- 

 looked the fact that my paper was written and delivered in 184S, and commenced to be 

 printed in the same year. The continuation of Embidre was printed February, 1849, 

 before Lucas' work was published. The report of Lucas by Schaum, in 185 1, contains 

 nothing about the habits of Embidae, nor any other report, as far as I know, before 

 Lucas' second paper in 1859.
