132 THE ENTOMOLOGIST. 



Listrodromus (quinquegiittatus, Gr.) and Neotypus, Foerst. {melano- 

 cephalus, Gml., and lapidator, Fabr.). Marshall has not adopted 

 the new genus, and Vollenhoven more recentl}' expresses strong 

 disapproval. Both species of Listrodromus in our list appear to 

 be exceedingly rare. The first species is better known by its 

 female name {nycthemerus). Gravenhorst says of the female, 

 " unicam feminam pedemontanum Bonellio debeo," which is the 

 one described; and of the male, " mas unicus (germanus ?) erat in 

 collectione Roentgeniana." Wesmael says, " this species appears 

 to be excessively rare in Belgium ; it is more than thirty years 

 since I took the three females mentioned in ni}^ ' Tentamen,' and 

 I have not seen it since." No other authors appear to know it. 

 There are four beautiful specimens in our National Collection 

 from Mr. Desvignes' collection (for description see B. M. Cat., 

 p. 18). L. lapidator is also rare, but much more generally 

 distributed than L. quinqueguttatus. Wesmael had three females 

 from Prussia, France, and Sweden, but did not know it from 

 Belgium. Tischbein says rare near Birkenfeld. It is very 

 doubtfully British. Mr. Desvignes introduced Gravenhorst's 

 L. nohilitator into his Catalogue (p. 29) from a specimen in his 

 own collection ; this is now in the British Museum, and certainly 

 is not L. lapidator. We have good coloured figures of both these 

 rare, but striking, species : — L. quinqueguttatus in Wesmael's 

 'Ichneumones Amblypygi Europsei' (plate, fig. 13), and L. lapi- 

 dator in Vollenhoven's ' Pinacographia' (pi. 27, fig. 8). 



Hypomecus, Wesm. 



Scutellum white ; abdomen black. 



Marks of head and thorax whitish straw; ring of antennae and 

 tarsi white ; femora and tibiae red ; I'ar. tarsi without the 

 white ring. - - - i. albitarsis, 5 — 6 lines. 



Wesmael gives good figures of the two sexes of this somewhat 

 variable insect (Ich. Ambly., pi., figs. 14 — 17), but specially tells 

 us that it has but little affinity with the preceding genera ; it still, 

 however, remains in the position where Wesmael left it pro- 

 visionally. Brischke bred this species from Acidalia trilineata* 

 Melanippe luctuata,-^ and Anticlea herherata. It is generall}' rare, 

 especially in Britain. Mr. Cameron has taken two specimens of 

 the variety without the white tarsal ring, at Cadder, near 

 Glasgow.
