On a new Species of Buprestidse. 219 



This point is illustrated by the accompanying diagram. 



It would appear from this comparison that the unpaired 

 genital pouch is interpolated between the two normal pairs; 

 and if this be granted it would have to be assumed either that 

 a segment which does not normally bear pouches intervenes 

 between the two which normally do, or that a partial dupli- 

 cation of the nephridia of one segment has occurred — a pheno- 

 menon which we find in its complete form in the family of 

 the Capitellidai. 



Mr. Punnett, Assistant Professor of Natural History in the 

 University of St. Andrews, who kindly gave me the abnormal 

 and the various normal specimens, informs me that they were 

 all obtained near Plymouth in the same locality. There can 

 thus be no doubt that this case is an actual variation, not a 

 local variety. 



XXX. — Description of a new Species of Buprestidaj. 

 By Chas. O. Waterhouse, V.P.E.S. 



Specimens of the species described below have been in the 

 Museum collection tor many years, separated as distinct from 

 Psiloptera quadrioculuta. A fresh specimen just brought 

 from Upper Egypt by Mr. D. A. MacAlister shows that the 

 differences between this and P. quadrioculata are constant, 

 and 1 therefore venture to give it a name, and I propose to 

 call it P. MacAlisteri after the donor. 



Psiloptera MacAlisteri, sp. n. 



P. quadrioculata; valde affinis ; vitta obliqua thoracis, elytrorurnque 

 vitta laterali cupreo-rubris ; corpore subtus tomento griseo-albo 

 induto, utrinque maculis majoribus circularibus ornato. 



Long. 20-27 mill. 



Very similar to P. quadrioculata, but perhaps a little less 

 convex. The general blackish-a?neous colour is the same, 

 but the impressions on tiie thorax and lateral stripe of the 

 elytra are coppery red. The front of the head is clothed with 

 pale yellow pile. The thorax is moderately closely and 

 strongly punctured, with a slight raised median line, and 

 four rotundate, smooth, black spots as in P. quadrioculata, 

 but the rugose surface surrounding them is coppery red and 

 forms a distinct oblique band from the anterior spot to the 

 base, leaving a triangular space at the posterior angle slightly
