rows on tlie anterior half, much more feebly, and confusedly, punctured 

 behind, usually with a fovea on suture before apex ; legs dark, metallic. 

 L. 3-4| mm. 



In the male the last abdominal segment is furnished with a trans- 

 verse fovea near its apical margin, and sometimes with a shallow central 

 furrow ; the apical margin of the intromittent organ is quite rounded. 



According to Weise, this species occurs on species of Epilobium and Srastica, and 

 also on (Enothera biennis ; there is BO much confusion between this and the next 

 species that I cannot be sure of the localities given, but I believe that it is by no 

 means uncommon ; as before remarked, specimens standing under the name of II . 

 ampelophaga in Dr. Power's collection have been returned to me by Herr Knitter aa 

 this species, and all the records given for the last-mentioned insect must probably be 

 referred to H. oleracea.* 



H. palustris, Weise. Suboval, rather short and broad, deep-blue 

 or nigro-cceruleous, not very shining ; frontal tubercles flat, terminated 

 behind with a depression or punctured line; thorax scarcely half as 

 broad again as long, rather convex, obsoletely punctured, with the 

 anterior angles scarcely callose and subrotundate, basal transverse furrow 

 not deep; elytra with rather coarse, but shallow, punctuation, humeral 

 callosities small, but plainly prominent. L. 3|-4j mm. 



Male with the first tarsal joint widened, and the last segment of the 

 abdomen with a narrow impunctate and bare central line ; the intromit- 

 tent organ, as in H. pusilla, is narrowed in front in almost straight lines 

 and forms a large point, and the deep channelled middle stria on the 

 under-side of the same is very broad. 



In damp places; local; taken in some numbers by Dr. Power at Wimbledon, and 

 marked by him as probably a new species ; I have also received it from the South of 

 England and from the Manchester district ; I believe that it stands in most of our 

 collections under the name of H. hflianthemi ; the punctuation will easily distinguish 

 the species ; in its dark blue colour it much resembles the car. montana of H.pusilla, 

 with which it appears to be sometimes mixed. 



H. pusilla, Duft. (cognata, Kuts. ; helianDiemi, All.). Oblong 

 ovate, convex, of an obscure greenish-bronze or bluish colour, shining ; 

 head with small frontal tubercles, obsoletely separated behind by a line 

 or punctured depression ; thorax half as broad again as long, a little 

 rounded at the sides, narrowed in front, with the anterior angles rounded 

 and obtuse and slightly callose, rather convex on disc, thickly and 

 extremely finely punctured, transverse furrow, as a rule, less strong than 

 in H. oleracea ; elytra at base only slightly broader than thorax, with a 

 very small and not very distinct humeral callosity, gradually widened 

 until behind middle, thickly and obsoletely punctured on disc, more 

 plainly towards suture ; in the male the last abdominal segment is flatly 

 impressed in middle and impunctate, and the intromittent or^an is 

 narrowed in front, in almost straight lines and forms a large point, the 

 angles at the sides being rounded ; Weise compares the species to a
