354 Tachinidae. 



apex of wing; discai angle rectangular with an appending fold; apical 

 cross-vein concave; a distinct costal spine. Squamulæ whitish. Hal- 

 teres brown. 



Female. Similar; frons considerably broader. 



Length. About 9 to 10 mm. 



Ph. echinura is rare in Denmark, I know eight specimens, six 

 males and two females; one specimen is from Amager, bred from 

 Lasiocampa trifolii on ^/g (Kryger), another from Hillerød bred on 

 '/g but the host not known; further it is taken in Ruderhegn and 

 Grib Skov; the other specimens are without particular locality, but 

 bred from L. trifolii. The species is hitherto known from Lasiocampa 

 guercus and trifolii and the non Danish Saturnia pyri. 



Geographical distribution: — Europe and into Asia minor; 

 it is not known north of Denmark. 



Remarks: One of my specimens has been determined by Stein 

 as obliquata Fall., and in his work from 1924 he declares ohliquata 

 and echinura as synonyms; this is no doubt not correct, obliquata 

 being distinguished among others by the quite small, parallel apical 

 scutellar bristles.

Species of medium size and bluish black colour, slightly pruinose, 

 generally with small red side spots on abdomen. Head fully as broad 

 as thorax, nearly flat behind, with the eye-margin a little broadened 

 downwards; it is higher than long. Frons broad, in female a little 

 broader than in male, a little protruding. Jowls narrow, one fourth 

 or fifth of the height of the eye. In both sexes ocellar and inner and 

 outer vertical bristles, in female two orbitals. Postocellar and occipital 

 bristles distinct. Behind postocular bristles rows of black hairs. 

 Frontal bristles descending to insertion of arista, the uppermost one 

 strong and reclinate in both sexes. Cheeks bare. Vibrissæ ascending 

 to insertion of arista, rather strong. Epistoma somewhat retreating, 

 a little reflected below. Eyes densely hairy. Antennæ inserted high 

 above middle of the eye, third joint about five times as long as second; 

 arista with second joint short. Thorax rectangular; four postsutural 

 dorsocentrals and three præ- and three postsutural acrostichals; 

 a præsutural intraalar bristle. Scutellum with four marginal bristles
