Show 380 MR. G. R. CROTCH ON AZOREAN COLEOPTERA. [Mar. 28, 147- C. VARIABILIS, Fabr. M. Drouet states this insect to be common throughout the group ; no trace of it, however, exists in the material now before me; yet it is impossible to believe that so well-known a species can have been confused with anything else. 148. CHILOCORUS BIPUSTULATUS, L. One specimen only, from Santa Maria. 149. SCYMNUS DURANTAE, Woll. Not rare on flowers in Terceira and Fayal. This species has been hitherto considered peculiar to Madeira, and is represented by a cognate form in the Canaries. 150. S. MINIMUS, Rossi. A few specimens have occurred in Fayal and Santa Maria. 151. RHIZOBIUS LITURA, Fabr. Very abundant in S. Miguel, Fayal, and Terceira, and presenting, as usual, considerable variation in colour. 152. BLAPS GAGES, L. S. Miguel and Fayal, in gardens, cellars, &c, not rare. This has been found on the Salvages. 153. B. SIMILIS, Latr. Very common in S. Miguel, Fayal, and Flores. 154. B., sp.? Two specimens were taken under a stone near the Lagoa das Farnas. I am not able to refer this to any described species, but am unwilling to add to the confusion already existing in the group hy adding another doubtful species. 155. HEGETER TRISTIS, Fabr. S. Miguel, Terceira, and Fayal, but rare. This insect is excessively abundant in Madeira and the Canaries. 156. OPATRUM HISPIDUM, Brulle. Abundant in S. Miguel, Terceira, and Fayal, and probably universal. 157. HELOPS AZORICUS, n. sp. Under the bark of a poplar tree at the Furnas, S. Miguel. This is very near one of the Madeiran species, but not, I think, identical with it. 158. PHALERIA BIMACULATA, Herbst. Abundant under dead fish at Horta, Fayal. M. Drouet records |
