INSECTA MADERENSIA. 191 



and summer months —particularly in the last of these districts, where in July 

 1850 I observed it by thousands on the outer canvass of my tent, whither it had 

 flown, in company with the Cortlcaria Fagi, towards the dusk of the evening. It 

 is a species of very wide geographical range, being recorded by Mannerhekn in 

 Lapland, Sweden, Finland, Siberia, Russia, Germany, England, France, Italy, 

 Armenia, the Caucasus, and even from Greenland. 



154. Lathridius transversus. 



L. ovatus antice subacuminatus, femigineus, capite prothoraceque (vix subpunctato-) rugosis, hoc 

 parvo subquadrato (angulis anticis baud ampliatis), ad latera complanato necnon ad basin pro- 

 fundius transversim impresso, elytris (antice sat profunde) punctato-striatis, antennis pedibusque 

 nifo-testaceis.

L. ovate, rather acuminated anteriorly, and bright ferruginous. Head and prot/iorax sculptured much 

 in the same manner as those of the L. minutus : the former obscurely channeled down tlie centre : 

 the latter smaller and narrower (especially in front) than in either of the other species,— being 

 subquadrate, and with the anterior angles hardly more developed (although much more rounded) 

 than the posterior ones ; with a tolerably distinct and rounded impression on the fore part of the 

 disk, and with the hinder transverse impression deeper than in either of the preceding species. 

 Elytra rather shining, and rounded at the sides, the widest part being a little behind the middle ; 

 somewhat deeply punctate-striated in front, but with the sculpture altogether much fainter 

 posterioriy,— the punctures towards the base however being rather large and distinct. Antenna 

 and legs (especially the former) a little paler than the rest of the surface. 



The somewhat anteriorly-acuminated outline and pallid hue of the present 

 insect, in conjunction mth the sculptm-e of its elytra (which is deep at theii- l^ase, 

 but fainter towards their apex), and the more distinct transverse impression and 

 less expanded front angles of its (comparatively small, narrow and subquack-ate) 

 prothorax, will be at once sufficient to separate it, prima facie, from the other 

 Madeii-an Lathrklli. Like the last, it is a species of wide geographical range, 

 abounding in all parts of Europe, and being recorded, in Asia, from Siberia to the 

 Caucasus. In Madeira it would seem to be decidedly scarce, or at any rate local, 

 —the exceedingly few specimens which have come beneath my notice having been 

 captui-ed by myself in the immediate vicinity of Fimchal and towards the upper 

 extremity of the Ribeii'o de Santa Luzia.
