nearly related to Phalacrus as some Entomologists imagine *, 

 I shall propose arranging the Byrrhidae between Diaperis and 

 Leiodes, leaving the Anthreni with the Dermestidae, to which 

 family I think they must belong, judging from the characters 

 of the larvae and the close affinity of the perfect insects to At- 

 tageniis trifasciatus. 



Our genus now contains only two species that are recorded 

 as inhabitants of Britain. 



1. S. picipes, Oliv. v. 2. No. 13. p. 9. n. 9. tab. 2. f. 9. — 

 Gyll. 1. 200. 8. 

 Almost half as long again as S. semistriata^ but not broader. 

 Oblong, black, somewhat eneous, shining, feet rufous, elytra 

 with the striae deep and continued throughout. 



Having no specimen of this insect, I have taken the above 

 characters from Gyllenhal. Mr. Dillwyn in his ' Memoranda, 

 &c.' says, " Simplocaria picipes ? On Crwmlyn Burrows, not 

 uncommon." 

 2. S. semistriata, ///. — Curtis Brit. Ent. pi. 335. 



This insect is very abundant in England under stones in 

 arid and sandy places. I have found it on Mousehold Heath 

 near Norwich, in gravel-pits ; on the shore of Southampton- 

 water; and in profusion, the middle of May, at the sides of 

 stones on the sands near the Ferry in the Isle of Portland. It 

 also occurs in Kensington Gardens ; and Mr. Dillwyn says, 

 " Common in putrid fungi in woods, and is often rather plen- 

 tiful about the beginning of summer on Crwmlyn Burrows." 

 I was not aware that these insects were fungivorous, which 

 would bring them near to Leiodes in economy ; but I hope 

 that the larvae will not go long undetected, as a knowledge of 

 them might enable the Entomologist to give a natural and 

 permanent location to the Byrrhidae. 



The plant is Chrysanthemum segetum (Corn Marigold). 



* Mr. Stephens has placed it as the type of the genus Phalacrus under 

 the specific name of 'maritimus' !
