462 Mr. T. D. A. Cockerel I on Fossil Arthropods 



])arallel rows are only very sparsely punctured *. The fossil 

 shows no colour-baiuls, but they may have existed in lite. 

 There is a group of Leplinoiai'sa, represented by L. jnncta 

 and its immediate allies, in which the rows of punctures are 

 single and even, as in C. allochhnin/s. 



Cerambycidae. 

 Leptura (?) bartoniana, sp. n. (PI. XVI. fig. 12.) 



Elytron as preserved 95 mm. long, but apex lost, probable 

 total length about 12mm.; width 3 mm.; costal margin 

 thickened ; humeral region with the usual large rounded 

 ])rominence ; surface throughout coarsely punctured on the 

 basal half, the punctures deei), suboval, inclined to be iu 

 longitudinal lines, but not regular, the intervals usually less 

 thau the width of a puncture, about seven punctures in 2 mm. 

 longitudinally ; on apical half or more of elytron the punc- 

 tures are fine and well separated ; on the descending outer 

 face below the humeral angle, the punctures are large and 

 run more or less in oblique lines.

This agrees with Ltj)tura, so far as can be seen. Com- 

 ])ared with the living L. crj/jr/jienn'is, it diftcrs by l)eiug much 

 less coarsely jjuncturcd in the apical region, and by the large 

 punctures not being at all confluent. On the other hand, 

 the punctures on the basal half are very much larger and 

 coarser than in L. sexmaculata or L. iustabilis. 



Scarabaeidae. 



PeUdnotites (gen. nov.) atavus, sp. n. (Fig. 6.) 



Elytron about 18 mm. long, width uncertain ; surface 

 with rows of tine punctures (6 or 7 in 2 mm.), and widely 

 scattered irregular similar punctures between. Ilnnieral 

 region with a well-d('fiiu>d thickened edge. A row of punc- 

 tures proceeds backward from the obtuse humeral angle, 

 very slowly diverging from the margin ; the next row of 

 punctures is about 3 mm. from this on the basal part of the 



* The ppecimen of L. undecimlincata, St§l, before me was collected by 

 Mrs. Cockorell at Aiitigun, Giinteniiiln. It has tlit> patttMii of head and 

 thorax as in Tower'H segregate L. diversa ('The Mechanism of Involution 

 iu Leptiiiotarsa,' \i\. 2. f. 4), but these parts are yellowiiih, nearly as in 

 L. pannmensis, and the elytral stripes are distinctly metallic green. It 

 will stand as rac(> tjuntcmiilrnm, and is, 1 presume, the L. yiiattinalmsis 

 wiiich Tower mentions but fails to describe.
