2212 Insects. 



before stated, in April. ] have also a male, captured at Bexley by Mr. 

 Saml. Stevens, in April. The time of appearance alone points out a 

 distinct species from A. Rosa?, which is an autumnal insect, appearing 

 about the middle of August. The present species always has two en- 

 tire segments red, A. Rosae only one, and that with generally a central 

 black stain, or varying as previously described, and being also coarsely 

 punctured beneath ; eximia, on the contrary, is very finely punctured. 

 The specimens captured by Mr. Weir are in the cabinet of Mr. Des- 

 vignes, who kindly gave me a fine specimen of the male : these, and 

 the males in Mr. Heale's cabinet, are all I have yet seen. 



Genus. — Ammobates, Latr., Si. Fargeau. 



Generic characters. — The maxillary palpi six-jointed ; the stem- 

 mata placed in triangle on the vertex ; the superior wings with two 

 sub-marginal cells. 



Sp. 1. Ammobates bicolor, St. Fargeau. 



Female. — (Length 3j — 4 lines). Black; the face clothed with a 

 short silvery white pubescence below the base of the antennae. Tho- 

 rax above coarsely punctured ; the sides, beneath, and the metathorax 

 laterally clothed with fine, short, white pubescence ; the outer margin 

 of the tegulae testaceous ; the wings slightly fuscous ; the legs have a 

 clothing of very short silvery white pubescence, the anterior pair rufo- 

 testaceous ; all the claws ferruginous. Abdomen, the three basal 

 segments ferruginous ; at the extreme lateral margin of the three basal 

 segments is a small patch of silvery white pubescence, the fourth and 

 fifth have a continuous broad fascia of the same colour ; the abdomen 

 ferruginous beneath. 



There is a specimen of this beautiful insect in the British Museum, 

 with a ticket attached, giving the locality of Leicester. I have placed 

 it in the Appendix, but have little doubt it will prove hereafter to be 

 an undoubted British insect ; since I observed that the hand-writing 

 on the label is the same as that on the specimen of Macropis labiata, 

 since proved to be indigenous, also taken at Leicester by Dr. Leach.
