ON A NEW PIMELIA BROUGHT BY MR. JOSEPH THOMSON FROM 



MOROCCO. 



BY B. G. STEYINSON, M.A., F.Z.S. 

 PlMELIA THOMSONI, Sp. 110V. 



Ovata, nigra, modice convexa, subnitida ; capite antice rugose-punctato, 

 supra leviter punctato, lateribus asperatis ; tliorace transverso, vertice fere 

 imp>unctato, lateribus confertim tuberculatis ; elytris ovatis, tuberculis plus 

 minusve seriatim positis, obtectis, his tuberculis ad basim sa?pius obsoletis, 

 costis externis denticulatis. Subtus omnino granulata, femoribus tibiisque 

 dense tuberculatis. Long., 13 — 16 mm. 



Entirely black, somewhat shining. The head, roughly punctate in front, is 

 almost smooth on the vertex, where only a few scattered punctures are visible, the 

 sides being distinctly asperate. The thorax is short but broad, almost impunctate 

 above, the sides covered with small but very distinct rounded tubercles. Scutellum 

 very minute. Elytra regularly oval, covered with rather large rounded tubercles, 

 arranged in fairly regular rows, two of these rows between the strongly marked 

 suture and the costal margin being usually more distinct than the rest. In the 

 majority of specimens at the base of the elytra near the suture the tubercles are 

 flattened and tend to disappear, leaving a somewhat triangular plane surface. To- 

 wards the middle of the elytra the tubercles adjoining the suture often merge, 

 producing transverse ruga?. The under-side of the insect is entirely covered with 

 tubercles, minute, but very distinct on the abdomen, stronger on the metasternum. 

 The femora and tibiee also are thickly covered with tubercles ; the tarsi being small 

 and rather feeble. Antennae moderately long and slender. The very scanty 

 pubescence black. 



Hub. : Glawr Atlas Mts., 6000—10,000 ft. 



This Pimelia seems to be most nearly allied to the species in- 

 habiting the Canary Isles (serrimargo, "Woll., &c), from all of which 

 it is, nevertheless, abundantly distinct. Mr. Thomson seems to have 

 met with it in some numbers, but only at high elevations of the Atlas 

 range. 



I have much pleasure in dedicating this interesting form to its 

 discoverer, as some return for his kindness in presenting me with the 

 Coleoptera collected by him in his adventurous journey through the 

 heart of Morocco.

Some insects common to Europe and Colorado. — To my list of insects common 

 to Europe and Colorado (ante, p. 67), I have several additions to make : Tachyporus 

 chrysomelinus, L., "Western Custer Co. ; T.jocosus, Say (Dr. Hamilton tells me this 

 is found in Europe and Asia), Mesa Co., and S.W. Pueblo Co. ; Oxytelus nitidulus,
