PGECILOSOMA GUTTATUM. 215 



stated to be "pech brun," which scarcely applies to 

 any specimens of pulveratum I have seen ; and, as 

 already stated, oltusum is said to be a quarter of a 

 line longer in the body, and two thirds in the wings 

 than pulveratum.

Plate XI, fig. 5, ? . 



Tmtliredo guttatum, Fall., Acta, Holm., 1807, 105, 39 (ex parte). 



Poecilosoma guttatum, Thorns., Opus. Ent., 289, 4 ; Hym. Scand.,

Black, ovate, broad, shining, covered (especially the legs) with a slight 

 grevish down ; the apex of anterior femora, all the knees, and the tibiae 

 in front sordid white ; the edge of the pronotum has a thin white line ; 

 the tegulae are black. Antennae a little longer than the abdomen ; the 

 third joint is a little longer than the fourth, the fifth, sixth, and seventh 

 are a very little thicker, the eighth and ninth thinner. The abdominal 

 segments are very faintly white at the junction, with faint indications 

 of white between the segments in the middle. The front is smooth, 

 shining, the sutures are invisible, antennal fovea large, ovate, and 

 shallow. Wings faintly black, lighter at the apex ; the first tr. cubital 

 nervure is present, the tr. radial is received in the apical fourth of the 

 third cubital cellule ; the costa and stigma black, the latter faintly fus- 

 cous round the edge. The cenchri are very large, oval, white ; blotch 

 rather small ; the sheath projecting ; hinder calcaria as long as a third 

 of the basal joint of the tarsus. Claws bifid. 



Length 3 3 lines. 



This insect is distinguished from submuticum by its 

 broadly ovate, short body, blackish wings, thicker and 

 longer antenna?, distinctly bifid claws and longer spurs, 

 shorter and broader third cubital cellule, and smaller 

 and much shallower antennal fovea. P. longicorne is 

 longer, less shining, the antennas thinner and longer, 

 the frontal sutures distinct, and antennal fovea deeper, 

 and the calcaria are shorter. 



It appears to be a rare species. I have only seen 

 one British specimen (a ? ). This was taken by Mr. 

 Fletcher at Worcester. 



On the Continent it has only been recorded from 

 Sweden, but possibly it is overlooked.
