Tcnthredo albipuncta, Fall., Acta, 1808, 104, 37. 



Macrophya Thorns., Opus., 295, 5 ; Hym. Scand., i,

 Species, i, 362 ; Cat., 46,* 35. 



Black, variegated with white. Antennas scarcely longer than the 

 abdomen, the fourth to eighth joints thickened, third nearly double the 

 length of fourth. Head shining, covered with a short pile; palpi, 

 clypeus, and labruni clear white, clypeus deeply incised. Thorax with 

 a very short pubescence, tegulse, pronotum, and a narrow stripe on the 

 pleurae white. Abdomen roundish, not longer than the head and 

 thorax, the segments at the sides and a large spot over anus white. 

 Legs with the apex of coxae, trochanters, and base of femora, apex of 

 four anterior femora and tibiae in front, posterior knees and femora, 

 except at the extreme base and apex, white. Wings hyaline, costa 

 fuscous, the stigma in the middle sordid- testaceous. 



In the 3 the anterior legs bear more of the white colour, being entirely 

 white in front, and the posterior femora are lined with white below ; 

 posterior tibiae are lined throughout with a black streak ; ventral 

 segments below and the anal lobes white. In the only specimen of 

 this sex that I have seen, the transverse radial nervure is almost 

 interstitial. 



Length 3^4 lines. 



Compared with albicincta, the present species is 

 smaller and has the head and thorax less pilose ; the 

 scutellum is black, slightly truncated and less convex ; 

 there are no marks on the vertex, the mouth and 

 tegulas are white, antennas short, and otherwise it is 

 readily separated by the marks on the pleurae. The 

 $ is easily known by the white ventral segments. 



Ab. a. Basal joint of posterior tarsus white ( $ ). 



Albipunda is not common. I have seen three 

 specimens only ; one from Eannoch, one from Muchalls, 

 Aberdeenshire (Trail), and another from Dairy (Sharp), 

 Mr. Bridgman records it from Norwich.
