370 MR. G. R. CROTCH ON AZOREAN COLEOPTERA. [Mar. 28, 



some water insects at least must have accompanied them. The spe- 

 cimens before me are darker than EngUsh ones, a circumstance pro- 

 bably to be accounted for by the method of preservation adopted. 



30. Agabus godmanni, n. sp. 



This fine species is by no means rare in Terceira, Fayal, and 

 Florcs ; and it is with some doubt that I have ventured to regard it 

 as new ; but it agrees with no published description that I have 

 access to. 



31. Gyrinus dejeani, BruUc. 



Common in Flores and Santa Maria, as also in TenerifFe, though not 

 in Madeira. M. Drouet in his brief list records no Water-beetles. 



32. Parnus i'rolifericornis, Rossi. 



S. Miguel and Santa Maria ; also in Graciosa and Flores (Drouet). 



33. Philhydrus lividus, Forst. 



Not rare in Terceira, but new to the Atlantic fauna, representing 

 the Ph. melanocepkalus of the other groups. 



34. Sph^ridium bipustulatum, Fabr. 



Common in S. Miguel, Santa Maria, Terceira, and Flores, and is 

 probabh^ as all the dung species may be presumed to be, universal. 



35. Dactylosternum abdominale, Fabr. 



Two specimens, under dung in Fayal. It is somewhat curious 

 that this species should be so rare here, occurring as it does in the 

 Mediterranean, Madeira, and the Canaries. 



36. Cercyon obsoletum, Gyll. 



At Ponte Delgada, S. Miguel, and also in the higher parts of the 

 island, but not common. 



37. C. littorale, Gyll. 



Fayal and S. Miguel ; one specimen only from each. This spe- 

 cies appears to decrease in abundance southwards. 



38. C. INQUINITUM, Woll. 



One specimen, at Ponte Delgada, S. Miguel. A Madeiran insect, 

 but probably of wider range in reality. 



39. C. centromaculatum, Sturm. 



Flores and S. Maria, not common. The name "ni(jriceps, Marsh.," 

 has been adopted by some for this species. The description is in- 

 a])]ilicable ; and he has in his collection placed specimens to repre- 

 sent four diflerent species ; hence he could not have bad a very clear 

 idea of its characters.
