scutellum smooth in the middle ; metathorax rugulose, rather 

 shiuiug. Segment 1 twice as long as broad, the sides parallel, 

 truncate, rugulose, and somewhat shining, like 2, which is half as 

 long as 3 and broader than 1 ; the rest smooth and shining ; 

 suturiform articulation strongly marked ; all the segments after 

 the 2d strongly compressed, cultriform. Terebra subexserted. 

 Valvula ventralis very large, cultrate, much sm'passing the anus.

The form of the abdomen renders this species very- 

 distinct. The shining black ventral valve is almost as 

 large as the rest of the abdomen, and with the short 

 terebra projects considerably beyond the anus. Viewed 

 from above, the abdomen is more compressed and acumi- 

 nated than in any other species here described. 



Two specimens, reared by Raynor from a hairy larva 

 preserved on the same card, are in Fitch's collection. 

 The white cocoons are four in number.

Black, with fuscous palpi ; legs testaceous, coxae and upper 

 trochanters black. Wings whitish, costa and stigma pale fusco- 

 testaceous, the latter edged with fuscous ; most of the nervixres 

 decolorous. Mesothorax and scutellum thickly punctulate, dull ; 

 metathorax rugulose with a smooth, marghied, medial, area. 

 Segment 1 a little longer than broad, margined, subcarinated in the 

 middle, truncated at the apex, rugulose ; segment 2 half as long as 

 3, and, with the rest, smooth and shining. Terebra ^- of the abdo- 

 men. (J 5 . Length, 1^ ; wings, 3^ lin. 



This must not be mistaken for xanthostigmus, Hal., 

 which has black femora. 



A (? taken by Fitch at Maldon, August 25th, 1884, is 

 the only specimen I have seen. It has been bred, 

 according to Reinhard, from Porthesia chri/sorrha'a, L., 

 P. similis, Fues., and Bomhijx neustria, L. Brischke 

 says that he has reared it from A crony eta psi, L., and 

 from the larva of a Chrysopa ; adding that the cocoons 

 are single or gregarious, cream-white or brownish yellow, 

 surrounded by shining silk. More than one species 

 seem to be here included.
