Lamp roq aster spec. A single specimen. 



Notopsila 

 {Pachycephala Dolesch., olim.) 

 This is merely a new name for the genus Pachycephala ) 

 Doleschall, 3 Bijdr. p. 43, the latter name being preoccupied several 

 times. Notojjsila is closely allied to Euprosopia; the species of the 

 former genus, show the following diflferences, that may be considered 

 generic, from Euprosopia potens, Wk. and maculipennis Gu^r. 



The clypeus is entirely concealed; the distance between the roots 

 of the antennae is greater, and equal to about one half the breadth of 

 the vertex; the third antennal joint is shorter; in two of my specimens 

 I perceive only one pair of very short vertical bristles, immediately 

 above the eye; in the third specimen (N. sexpunctata) even that is 

 wanting (broken off?); there are no other cephalic bristles. The scu- 

 tellum is slightly emarginate at the tip, and three (sometimes four?) 

 short bristles are inserted on the projection on each side of the emar- 

 gination. (In the Euprosopiae the position of the three scutellar pairs of 

 bristles is different; one pair on the apex, while the two other pairs 

 are placed on the convex surface of the scutellum, the anterior pair 

 being about the middle of the distance between the base and the tip 

 of the scutellum). Of the other thoracic bristles I perceive a humeral 

 and two posthumeral ones; two pairs of praescutellar bristles; the first 

 supra-alar bristle, almost in a line with the praescutellar, a little on 

 the side of the scutellar bridge; the second, above the alar frenum; 

 they are all very short. (In the Euprosopiae the distribution in the same, 

 except that the third supra-alar bristle, on the edge of the cavity, is 

 also present, and that all the bristles are longer) ; no pleural bristles* — 

 The face is flatter than in the Euprosopiae; the antennae are imbedded 

 in the deep antennal furrows; the venation is the same; the three species 

 have the same blackish gray color and mottled wings, as the two 

 Euprosopiae; but they have besides, a fine golden yellow appressed 

 pubescence, which that species has not. 



Doleschall's typical species and mine, may be tabulated thus: 

 Antennae and tibiae black .... Mohnikei Dol. 

 Antennae and tibiae red 



Face with two deep -black spots at the base of the an- 

 tennae and four other spots besides 



sexpunctata n. sp. 

 Face without black spots .... curt a n. sp. 



This Pachycephala has nothing to do with the Pachycephala 

 Mus, Berol. mentioned by Loew in Monogr. Ill, 38.
