391 INSECTA MADERENSIA. 



their funiculus perceptibly longer than any of the follomng ones ; and mth their scape curved 

 throughout its entire length, being more gradually (although considerably) incrassated at its 

 apex ; the latter with all their tibia slightly curved, — and with their fuur posterior ones very 

 distinctly acuminated towards their extremity. \ 



The tlistinctions between the present species and the preceding one hare been 

 ah'eady doubly pointed out, — the peculiarities of their respective antennce and legs 

 being more than sufficient, even alone, to identify them. The construction of the 

 tibise of the aS*. curvipes is in fact of a very singular nature, theu* gradually 

 diminishing breadth, from the base, added to their slightly arcuated form (more 

 especially cA^dent however in the two hinder pau's), gi^^ing them a most unusual 

 and anomalous appearance. It is rather more common than the S. Madera;, and 

 of a somewhat higher range ; but in other respects its habits are very similar to 

 those of that insect. On the mountain-slopes above Funchal, particularly towards 

 the Pico da Silva (on the Caminho de Meio), I have constantly observed it from 

 the autumn to the early spring ; and dui'ing July of 1850 I took it, sparingly, in 

 the chestnut- woods of Santa Anna. 



Genus 128. TRACHYPHLffiUS. 



Germar, Ins. Spec. i. 403 (1824). 



Corpus sat parvum, ovatum, convexum, plerumquc dcnsissime squamosum et parce setosum : i-ostro 

 longiusculo, supra piano, lineari, minus lato, ad apicem triangulariter emargiuato ; scrohe pro- 

 funda subrectii elongata, ad medium oculorum ascendente sed cos vix attingente ; oculis rotun- 

 datis : prothorace brevi transverso, ad latera subampliato-rotundato, antice valde truncato : scutello 

 haud ohservando : ebjtris subconnatis, basi conjunctim subintegris : alis obsoletis. Antennw 

 breves crassa; et parce setosa;, pone apicem rostri insertje ; scapo recto, apicem versus incrassato ; 

 funiculo 7-articulato, articulo primo magno crasso obconico, secundo gracihore et paulo breviore, 

 reliquis brevibus transversis; clava ovata, obscurissime articulata. Pedes breviusculi, valde 

 robusti, setosi : femoribus subclavatis : tibiis rectis, ad apicem fortiter spinuloso-ciliatis, ad apicem 

 internum (pra;sertim in postcrioribus) in uncum minutum acutum detlexum productis, necnou 

 intus ante apicem leviter constrictis. 



The common Em-opeau genus Trachyplilcexts (which appears to possess but a 

 single representative in the Madeu'a Islands) may be kno^^^l fi-om its allies with 

 wliich we have here to do by the ovate, convex, densely scaly, and more or less 

 setose bodies of the insects which compose it, by theu' short and transverse pro- 

 thorax, linear and ratlicr elongated rostrum (into which the antcnnrc are inserted 

 at a considerable distance from the apex), and by their uncm-ved tibia; and scape. 

 They reside principally beneath stones, particularly in sandy or gravelly spots ; 

 and are, some of them, I believe, occasionally attendant uj)on i\jits.
