INSECTA MADERENSIA. 315 



Head) and in the Eibeii-o de Santa Lvizia ; and likewise, during May and June, 

 in the chestnut-woods of Santa Anna. Of the car. /3. (captiu'ed by myself, on the 

 summit of the Dezerta Grande, in May 1860) I possess but a single example ; and 

 hence it is scarcely possible to decide for certain whether the small distinctive 

 features which it presents be indicative of an additional species, or merely of a 

 local state of the C. conicolUs. After a careful examination, I am inclined to the 

 latter opinion, since even Madeii-an specimens do occasionally show a slight ten- 

 dency to have their punctiu-es and elytral striae perceptibly developed ; whilst, on 

 the other hand, the small differences of its figure are scarcely more than those 

 which cannot fail to be acknowledged in the insular modifications of the C. liici- 

 fngus : nevertheless it is clear that a larger number of individuals should be 

 obtained before we pronounce absolutely on the subject. 



Genus 110. CAULOPHILUS, Woll. (Tab. VI. fig. 4.) 



Corpus parvum, lineare, depressum, sculpturatum, glabrum : rostro (VI. 4 a) longiusculo subarcuato 

 subdeflexo; oculis magnis rotimdatis : prothorace ad latera rotundato : scutello distiucto sub- 

 rotundato : eZy/m parallelis profunde sulcatis : afe, nisi fallor, obsoletis. Antenna (VI. 4 6) et 

 pedes (VI. 4 c) fere ut in Uaulotrupide, sed ill<B paulo crassiores. 



A KavKo<i caulis, et </)t\o? amicus. 



The hitherto unique insect from which the above diagnosis has been di"awn out 

 possesses much in common with Phloeopliagus and Caulotrupis, though with 

 distinctive characters of its own sufiicient, as I believe, to warrant its isolation 

 from both of them. Its linear outline, and depressed, deeply sculptured surface, 

 in conjunction with its comparatively large eyes and scutellum, will at once serv^e 

 to separate it from the latter ; whilst from the former its incrassated antennae, 

 obsolete wings, and flattened, parallel body will, apart from minor differences, 

 equally remove it. 



241. Caulophilus sculpturatus, WoU. (Tab. VI. fig. 4.) 

 C. linearis rufo-piceus subnitidus depressus, prothorace profunde punctato, elytris profunde sub- 



crenato-sulcatis, interstitiis seriatim punctatis, antennarum clava ferruginea. 

 Long. Corp. lin. 1|. 



Habitat Maderam rarissimus : exemplar unicum, sero autumno a.d. 1847 prope Cabo Gerajao a 

 meipso detectum, tantum vidi. 



C. linear, depressed, rufo-piceous, and slightly shining. Head and prothorax (especially the latter) 

 deeply and closely punctured. Elytra parallel, deeply subcrenate-sulcate, the interstices with a 

 longitudinal row of small punctures down each. Antenna with their club ferruginous. Legs 

 rufo-piceous. 



Apparently extremely rare ; the only specimen which I have seen having been
