Carcelia. 375 



Length 8 — Hmm; the species thiis does not exceed quadri- 

 pustulata much as to length, but it gives the impression of being 

 larger, on accoiint of its greater breadth. 



W. xanthogastra does not seem to be imcommon in Denmark, 

 though most of our specimens are from earUer times; of locahties I 

 only know Ordrup, Lolland at Maribo and in Jutland at Sønderborg; 

 the dates are in May. As hosts are known Acherontia atropos, Sphinx 

 ligustri, Chaerocampa elpenor^ Smerinthus ocellata and popiili, Dendro- 

 limus pirii, Acronycta tridens, Brachyonycha sphinx and Catocala 

 sponsa] with us it has been bred from Sphinx ligustri and Chaero- 

 campa elpenor. Nielsen has (Vidensk. Medd. fra Dansk natnrh. Foren. 

 65, 1913, 301) treated its biology, which is similar to that of qiiadri- 

 pustulata; the species choses mainly large larvæ as hosts, especially 

 Sphinx ligustri; the author found 74 larvæ in one Sphinx pupa. The 

 larvæ bores out of the host larva, or rarely this reaches to pupate 

 before; no doubt more than one yearly brood. 



Geographical distribution: — Europe down into Italy; towards 

 the north to southern Sweden (Ringdahl). 



Remarks: As Stein ascribes his xanthogastra three sternopleural 

 bristles it cannot be the present species; thereagainst his ligustri 

 n. sp. seems to be the true xanthogastra^ an opinion expressed to me 

 by Dr. Villeneuve. 



82. Capcelia R. D. 



Species of medium size and of dark colour with greyish pruinosity, 

 in most species the male with reddish side spots on abdomen. The 

 genus is in most respects similar to Winthemia. Head a little broader 

 than thorax, somewhat short and quite flat behind or almost a little 

 concave, and not puffed out below, much higher than long. Frons 

 almost not protruding. Eyes high, occupying nearly the w^hole side 

 parts of the head, so that the jowls are small and not descending. 

 In both sexes ocellar and inner vertical bristles, in female also outer 

 verticals and two orbitals. Small postocellar and occipital bristles. 

 Postocular bristles fme, no black hairs behind them. Frontal bristles 

 descending to about the end of second antennal joint, or farther down 

 to insertion of arista; in both sexes two upper strong and reclinate. 

 Cheeks bare. Vibrissæ only slightly ascending, rarely about to middle. 

 Antennæ inserted above middle of the eye, third joint two to three 

 times as long as second. Thorax nearly square; bristles as in Win-
