the two. Thomson gives M. crassula, Klug, as a synonym o£ albipunc- 

 tata, but this is not the case, King's species being larger ; it has yellow- 

 instead of white markings ; the mark on the pleurae is larger, the 

 pronotum is broadly marked with yellowish-white, the hinder tibiae are 

 not black at the base, nor is the stigma testaceous ; the 2ud recurrent 

 nervure is almost interatitiate, while in Fallen's species it is received 

 near the middle of the cellule. 



There seems to be some ambiguity about what has been written 

 concerning the larva of M. rihis. Schrank describes the larva as being 

 green, with two minute dots on the head, and as feeding on Hibes. 

 Dours (Cat. Syn., 22) states that it lives on the gooseberry, and has 

 for parasites Pygostolus sticticus and MesoJeius armiUatorius, Gr., = 

 luteifrons, Gr. (according to Goureau). Kaltenbach, on the other 

 hand, says that it is suspected to have a similar history to alhicincta. 

 The larva he describes as being very like that of the latter ; the head 

 orange-yellow, with a black mark on vertex and anus, and without any 

 lateral markings. It may be added further, that Eondani (in his paper 

 "Degli Insetti nocive e dei loro parassiti, Bull. Ent. Ital," vi) states 

 that M. ribis feeds on Bibes ruhruni and c/rossuJaria, but it is evident 

 from the list of parasites he gives that his observations refer to the 

 too-well-known JSfematus ribesil. 



Taxonus Pletcheei, sp. n. 



Black, shining, covered with a scattered piibescencc, the labrum, edge of prono- 

 tum and tegulse, white ; legs reddish, paler at the base, and at the anterior tibise in 

 front I the apex of the tibise and tarsi black ; wings almost hyaline, costa and stigma 

 black, marginal nervure nearly interstitiate. Length, 2 lines ; alar exp. 5? lines. 



This little insect stands between T. f/lnlratus, Fall., and T. aJblpes, 

 Thorns. From the former it may be easily known by its smaller size 

 (it is three-quarters of a line shorter than my smallest ^ of glalratint 

 and one and a quarter than the largest), white tegulae and edge of 

 pronotum ; the body wants the coppery-violet tint, and the apices of 

 the tibiae are black. Albijyes agrees with it in haviug the teguhc white, 

 but it has the pronotum entirely black, the body almost glabrous, the 

 legs are yellowish-white, and the four anterior tarsi and apices of tibia) 

 are not black, while it is also a Inrger species.

 have named it), near that place on the 30th July, 1877, on alder.
