^ MB. SMITH S CATALOGUE OF IITMENOPTEROUS INSECTS 



Galathea with short rostrum, armed on each side with 4 teeth, the two 

 posterior being less important than the two anterior. The fingers of 

 the chelae impinge through their whole length ; outer margin of the 

 hand furnished with 3 or 4 small spines. 



Hab. Trawling-ground, Plymouth, common; Moray Frith, Scotland. 



This species unites G. Andrewsii with G. nexa, and, I think, has 

 often been mistaken for the young of the latter ; but G. nexa, 

 so far as my experience goes, is a species peculiar to the north of 

 England, whereas G. dispersa, I anticipate, will be found to be the 

 most universally dispersed, in deep water, of any of the species 

 known. It can always be detected from G. nexa by the form of the 

 hand and the manner in which the fingers impinge : in G. nexa the 

 hand is broad tow^ards the extremity, and the fingers meet only at 

 the apex ; in G. dispersa the hand gradually narrows to the apex, 

 and the fingers meet each other through their whole length, the 

 inner margin of the finger being finely serrated, the thumb not. 



It also may be distinguished from G. Andrewsii by the breadth 

 of the hands, which are narrow and round in G. Andrewsii, and 

 moderately broad and flat in G. dispersa. 



By an examination of the texture of the integument under a 

 magnifying power of low degree, the surface of G. dispersa will be 

 seen distinctly to differ from that of any of the others ; it is covered 

 w^ith flat scales, fringed with short cilia. The length of the animal, 

 including the arms, is about 2| inches. 



Catalogue of Hymenopterous Insects collected at Celebes by Mr. 

 A. E. Wallace. By FredeeiCk: Smith, Esq., Assistant in 

 the Zoological Department, B^ish Museum. Communicated

[Eead April 15th, 1858.] 



This collection of the Hymenoptera of Celebes is specially inter- 

 esting, as adding greatly to our know^ledge of the geographical 

 range of many well-known species, while the additions made to 

 the Fossorial group contain many of great beauty and rarity. A 

 new species belonging to the tribe of Solitary Wasps, Odynerus 

 clavicornis, is perhaps the most interesting insect in the collection ; 

 this Wasp has clavate antennae, the flagellum being broadly dilated 

 towards the apex, convex above and concave beneath. I am not 

 acquainted with any other insect belonging to the Vespidious 

 group which exhibits such an anomaly.
