INSECTA MADERENSIA. 3 



extremely abundant ; and it lias been, likewise, taken by Professor Heer near the 

 Mount Cliureli. It makes its appearance about the middle of July, and lasts until 

 the following spring. I have not observed it in any of the other islands of the 

 group. 



2. Taras sutiu-alis. 

 T. testaceus leviter punctatus, elytris striatis, capite prothoraceque parvo rufo-ferrugineis, elytrorum 



siitoi-a lineolaque postica abbreviata obscui'e fuscis. 

 Long, coi'p. lin. 4-4i. 



Cymindis suturalis, Dej. Spec, des Col. i. 206 (1825). 



Habitat sub lapidibus in locis arenosis ad oram maritimam ins. Portus Sancti, tempore vemali, vulga- 

 tissimus : unicum exemplai" etiam ad summum cacumen ins. Desertse Grandis mense Januario 

 A.D. 1849 inveni. 



T. pale testaceous, elongate. Head and prothorax narrower tlian in the last species, and more finely 

 punctured and polished, rufo-testaceous ; the latter channelled, small, and romided behind. 

 Elytra slightly longer and narrower than in T. lineatus, depressed, regularly and distinctly 

 striated, the striae impunctate, the interstices rather deeply punctured ; the suture, especially 

 posteriorly, a short stria springing from it behind the middle (and extending, anteriorly, about 

 half-way to the base), and a narrow lateral one, distinct behind but vanishing in front, more or 

 less obscurely fuscescent, or piceous-black. 



The present Tarns, which has been hitherto known as peculiarly Egyptian, is 

 evidently very nearly alKed, in a natiu-al arrangement, to the T. Uneata ; and so 

 it was considered by Dejean, who, in his Species general des Coleopteres, in 1825, 

 placed the two insects ahnost in juxtaposition. It is interesting therefore to find 

 both of them inliabiting the Madeira Islands, and to remark moreover that they 

 are the only Tavl, so far at least as I have hitherto observed, which the group 

 produces. The T. suturalis is exceedingly abundant iu Porto Santo, occui'ring 

 beneath stones in diy sandy spots about the sea-shore, particularly to the east and 

 west of the Cidade and on the Campo de Baxo. It would seem to be especially 

 common during the winter months. It does not exist, apparently, in Madeii'a 

 proper, being there replaced by the previous species : but on the extreme summit 

 of the Dezerta Grande I detected, dui-ing January 1849, a single specimen in the 

 cre-vice of a weather-beaten rock. It is a common insect on the shores at Alex- 

 andria, from whence I possess a fine series collected by my friend Dr. H. Schaum 

 of Berlin. 



Genus 2. DROMIUS. 



Bonelli, Observat. Ent. i. tah. synopt. (1813). 



Corpxis parvum, oblongo-ovatum, depressum : protlwrace subcordato : elytris apice truncatis : ahs 

 mode amplis, modo (ut in speciebus nostris plurimis obtinet) obsoletis. Antenna filiformes,
