(s.g. Acmceops, Lee. ) P. COLLAKIB, L. 



P. cerambyclformis, Schrank. (nctomaculata, Schall.; s.g. ludolia, 

 Muls.). Black, clothed with greyish pubescence, which is thickest and 

 .longest on the thorax, elytra testaceous, with four variable spots on each, 

 two behind base situated in the same more or less oblique line and often 

 confluent, one just behind middle, and the fourth at apex ; head con- 

 siderably produced before antennae, closely punctured ; thorax broadest 

 behind and narrowed in front, with posterior angles somewhat pro- 

 jecting, closely punctured ; elytra broad in female, narrower in male, 

 rather closely but distinctly punct ired ; legs and antennae black ; in 

 the male the general form is smaller and narrower than in the female,

P. sexmaculata, L. (trifasciata, F.; s.g. ludolia, Muls.). Closely 

 allied to the preceding, but may be distinguished by its narrower and 

 more parallel form, more shining appearance, the much scantier and 

 tiner pubescence, finer punctuation, blacker colour, and shorter basal 

 joint of the posterior tarsi. The elytra also are differently marked, 

 being black, with three pale yellow, transverse, angular bands, one at 

 base, one a little before the middle, and one at about two-thirds of their 

 length. L. 8-11 mm. 



Two specimens taken by Mrs. King on fir palings immediately adjoining the 

 Rothiemurehus Forest, Aviemore, Inverness-shire, on June 30th aud July 2nd, 1877 ; 

 the species is rather common in Sweden, North (jerinany, &c. 



P. collaris, L. (Acmceops collaris, Lee.). Smaller than either of 

 the preceding, and easily distinguished by having the eyes entire, and 

 by its colour, which is entirely black or bluish-black with the thorax 

 bright red ; the abdomen also is red ; upper surface clothed with long 

 fuscous pubescence ; thorax much narrower than elytra, narrowed in 

 front and broadest behind, diffusely and finely punctured ; elytra sub- 

 parallel, with shoulders well marked, depressed on disc, rather closely, 

 but strongly aud somewhat rugosely punctured ; legs rather long, black. 

 L. 7-9 mm.
