3620 Insects. 



obtaining seventy-five specimens of Cossonus ; as of old, more espe- 

 cially abundant in decayed sycamores and under the loose bark of 

 plane trees. Being most intent on procuring a good series of this in- 

 sect, T searched for little else ; nevertheless, Thanasimus formicarius, 

 a few species of Cis, and some minute Brachelytra, were tolerably 

 abundant in the same spots. Upon the whole, my past experience 

 entomological, in Devonshire and Cornwall, would point to Mount 

 Edgecumbe as decidedly the most productive locality in the two conn- 

 ties. Whether it be from the variety of altitudes we obtain in a small 

 compass, the peculiarity of the soil, or the quantity of old timber which 

 has been allowed to remain for centuries untouched both in the park 

 and grounds, or perchance, which is not improbable, from a combina- 

 tion of all three, I am unable to say. Nevertheless, it does certainly 

 appear that Mount Edgecumbe possesses some peculiar advantages 

 over the surrounding districts, being altogether an exception to the 

 characteristically barren country of the "far West." 



Crossing over from Plymouth into Cornwall, my next station of 

 permanence was Newton Park, near Callington, where a remote and 

 densely wooded country, the property principally of my friend, E. 

 Collins, Esq., was before me. Constant rain, however, prevented a 

 proper investigation of this very interesting district, which, but for my 

 opportunities of exploring it formerly, might have left me with the im- 

 pression that it also, like Mount Edgecumbe, was an exception to the 

 general rule. This however is not the case, for the valley of the Lyn- 

 her, profitable as it may seem at first sight, and beautiful as it assur- 

 edly is in the picturesque, contains but little that is scarce. Troops 

 of Malthini and Telephori are foremost to be observed ; which, with 

 the large Phyllobius calcaratus and Galeruca Capreae, make their 

 appearance everywhere. In the older trees I remarked the excessive 

 ravages of Sinodendron cylindricum, which, with the common Rhagia 

 and a small Rhysophogus, would seem to do the work of destruction 

 pretty rapidly. In the flowers of the hawthorn I captured Meligethes 

 melanocephalus not uncommonly ; and on thistles by the edges of the 

 river Lynher, in the meadows below, Rhinobatus planus was tolerably 

 abundant. 



In the vicinity of Launceston, where I next took up my quarters, I 

 did not obtain much ; partly because I searched but little, and partly 

 because the weather was unpropitious. Nevertheless, I had so com- 

 pletely ransacked the neighbourhood eight years ago, that I the less 

 regretted the few opportunities which occurred of renewing my ac- 

 quaintance with it. A few species however might be recorded ; such
