332 Mr. Waterhouse on a new species of Lophotus. 



each side of the thorax, one on the trochanter of each of the 

 4 anterior legs ; a longitudinal row of spots adorns the under 

 side of the abdomen, one to each segment, and the two basal 

 segments have moreover a spot on either side ; a large patch 

 is situated on the apical portion of each elytron, and all the 

 femora have a pale ring near the apex : the colour of these 

 spots is sometimes white, sometimes yellow, and occasionally 

 some brilliant pale blue scales margin the white ones, espe- 

 cially on the legs, and a patch of blue scales is generally ap- 

 parent beneath the spots on the apical portion of the elytra. 

 Several specimens of this species were brought home by Mr. 

 Darwin ; some of them are from Chiloe, and others from 

 Ynche Island, Chonos Archipelago. 



Sp. 4. Lophotus Eschscholtzi, Scho. Tom. 2, pars prima, p. 316. 



Lophotus trifasciatus. Hope, MS. 



L. niger, squamis albis dispersis ; elytris fascias tres latas et albas 

 exhibentibus, necnon ad apicem notam albam : tuberculis 

 duobus parvis et angularibus super oculos ; thorace punctis 

 confluentibus ; elytris insigniter punctato- striate. 



This species is readily distinguished from either of the pre- 

 ceding by the black and white fascice which adorn the elytra. 

 It agrees with the description of Lophotus Eschscholtzi, if we 

 may suppose Schoenherr's specimen a little rubbed. In per- 

 fect specimens the elytra (which are shorter and broader than 

 in other species) are densely clothed with white scales, ex- 

 cepting in certain parts, and these unclothed portions form 

 fasciae : a small black spot is observable on each shoulder, a 

 triangular black patch (sometimes confluent with the shoulder- 

 spot) on the scutellum ; behind these are two black fascice, 

 the first of which is interrupted in the middle ; and on the 

 apical portion of the elytra is an irregular black mark. On 

 the head, thorax, legs, and the whole of the under parts of 

 the body, are scattered white scales. 



One specimen of this insect was brought from Valparaiso 

 by Mr. Darwin, who says " it first appears in November, is 

 very abundant, and injurious to the young shoots of plums 

 and peaches."
