520 INSECTA MADERENSIA. 



395. Helops futilis, JFoII. (Tab. XII. fig. 7.) 



H. oblongo-subovatus ferrugineus subopacus, prothorace confertissime punctulato latiusculo sub- 

 quadi-ato, elytris subcrenato-striatis, interstitiis obsoletissime punctulatis, autennis pedibusque 

 testaceis. 

 Vai: a. paulo obscurior, elytrorum interstitiis apicem versus leviter seriatim tuberculatis. (In 



Maderd status typicus.) 

 Var. ^. paulo elarior, elytrorum tuberculis obsoletis. (Ins. Deserta Grandis.) 

 Long. coqi. lin. 2|-3|. 



Habitat sub lapidibus Maderse et Desertse Grandis, rarior. 



H. somewhat oblong-ovate (or nearly oblong), ferruginoiis, and almost opake. P?"o/Aora<r rather wide, 

 convex, and subquadrate ; deeply and exceedingly closely punctulated. Elytra finely striated 

 (the striiE obscurely crenatcd) ; the interstices with most minutely impressed points (sometimes 

 scarcely perceptible). Legs and antennae testaceous. 



Var. a., of a slightly obscurer hue (the edges of the prothorax and the extreme base of the elytra 

 however being usually more rufescent, or chestnut) ; the clytral interstices with the hinder 

 tubercles tolerably apparent ; and the apex of the antcnnnp distinctly infuscated. [Madeira.) 



Var. /3. of a clearer, or more rufescent hue; the elytral interstices with the tubercles obsolete; and 

 the apex of the antennae less distinctly infuscated. (The state peculiar to the Dezerta Grande.) 



Apparently the rarest of the Helopidce here described ; and, like the following 

 two, of a paler coloui* than the generality of them. Eroni both of those, hoAvever, 

 it may be known by its smaller bulk, and by the punctures of its prothorax being 

 extremely dense, whilst those on the interstices of its elytra are scarcely per- 

 ceptible. The only locality in Madeira proper in which I have myself observed it 

 is at Camacha, — where, on the 2nd of March 1848, I captured it sparingly fi-om 

 beneath stones on the level grassy plain close to the Quinta of ]Mr. Bean. It has 

 however been subsequently taken by M. Rousset near Funchal, and by Professor 

 Heer at the Mount Church. It would seem to exist likewise on the Dezerta 

 Grande, — from whence I obtained a pair (of a slightly brighter hue, and with the 

 hinder tubercles hardly distinguishable) during my sojourn on that island, with 

 the Rev. W. J. Armitagc, in January 1849. 



396. Helops cinnamomeus, WoU. (Tab. XII. fig. 8.) 

 H. elongato-ovatus ferrugineus subnitidus, prothorace confertim punctulato subquadrato, elytris 



minutely impressed points (so small as to be scarcely perceptible without the aid of a powerful 

 glass), and without any appearance of tubercles citlier before or behind. Legs and antenna didl 

 ferruginous, being more or less infuscated in parts. 



It may be regarded as the Canariau representative of the H. congregatus, from wliich however »peci- 

 Jically it is abundantly distuict.
