I am not sure of the sex of 

 species, but believe it to be a male. 



leviter couca\o, antice pnifuiule emarginato, lateribus sat 

 fortitor rotuudatis mox ante basin fere parallelis, angulis 

 ])osticis roctis ; elytris obscure 6-seriatim caiicellato-puiictu- 

 latis, intcrstitio 'i' longe ultra uiediuiu carinato pone medium 

 tuberculis 2 vel 3 permagnis ai-mato, interstitio 7° toto 

 tuberculato (tuberculis apicem \ersus permagnis), interstitiis 

 ceteiis vix distinctis, parte inter carinas abrupte planata, 

 liumeris sat acutis antrorsum directis ; sternis abdomineque 

 ut L. biordiiiail ; elytrorum interstitiis tertiis retrorsum 

 leviter conxergentibus. Long., 12 1. ; lat., 4^ 1. 



the type of this remarkable 

 The species may be at once 

 distinguished from all its allies by the perfectly flat median space 

 of the prothorax antl elytra (viewed fnmi the side the upper out- 

 line appears as a perfectly continuous sti'aight line from the front 

 of the prothorax to the posterior declivity of the elytra), together 

 with the fifth interstice being quite devoid of tubercles, and 

 scarcely distinguished from the fourth and sixth interstices. 

 Altliough not taken by the Elder Expedition, this species is 

 sufficiently allied in its characters and habitat to the above to be 

 suitably described here.

L. Interioris, sp. nov. Valde elongatus ; minus convexus ; dense 

 nmrino-squamosus ; rostro fere ut L. gravis, sed baud con- 

 cavo ; prothorace (juam longiori (et postice quam antice) 

 quarta parte latiori, vernnculato-ruguloso, anguste sat pro- 

 funde canfdiculato, paullo pone apicem transversim sulcato, 

 antice profuude emarginato, postice vix bisinuato, lateribus 

 leviter arcuatis, angulis posticis subrectis; elytris punctulato- 

 striatis, puncturis in striis minus crebris, interstitiis sat 

 latis, 3° 5° que leviter convexis postice in tuberculis minus 

 elevatis fractis, interstitio 7° toto tuberculis parvis instructis, 

 interstitio 1° (subsuturali) postice tuberculo medico instructo, 

 humeris rotundatis ; prosterno antice vix tuberculato pone 

 coxas tuberculo bitido instructo ; metasterno simplici ; seg-

Not much like any species of Laptops previously described, but 

 I'esembling Hopei, Schonh., in its vestiture, though of a darker 

 colour. The comparatively slender antennse (with the scape ex- 

 ceptionally long) and legs, together with the elongate form, give 

 it an aspect less robust than that of most of its congeners. The 

 sculpture of the elytra is nmeh like that of a female L. tribulus, 

 and does not differ nuich sexually. From L. trihulns this specie.s
