CONTRIBUTIONS TO OUR KNOWLEDGE OF THE BRITISH BRACONID^. 249 



The number 105 refers to the column of the * Guide,' 3 is 

 the number of ochropes in the species listed, t signifies that Curtis 

 and Dale were the first to discover the species in Britain, and 

 Mr. Waterston thinks that x probably indicates that the speci- 

 mens are in Dale's Collection. I have been much interested to 

 find nine ancient examples in this collection without data, but 

 all under the name of ochropes, Curt. In all probability these 

 specimens were named by Curtis and came from Dorset, as in 

 his ' History of Glanvilles Wootton ' C. W. Dale records the 

 species as common ; the collection also contains a female from 

 Shetland (1890), and a male labelled " G. W., 1898." The only 

 example I have taken myself, a female, was swept from low 

 bushes in a lane at Hunstanton, Norfolk, May 31st, 1918. In 

 Fitch's Collection is a female ticketed " delusor '?.''' 



This species differs from tuberculatus, Wesm., in having the 

 radius straight, second cubital areolet subtriangular and not 

 quadrate, and tubercles of first abdominal segment not prominent, 

 from ffloriatorius, Pauz, in the much smaller size and colour of 

 hind tibise, and from delusor, \Yesm., in the colour of hind coxae, 

 etc., and length of terebra. 



Earinus delusor, Wesm.* 



Considered by Marshall to be the same as Bassus gloriatorius, 

 Panz,f though that species has a length of 7 mm. while delusor 

 attains only 5 mm. Later writers have again separated the 

 two so that we can no longer retain gloriatorius in the British 

 list, Delusor has the hind coxa3 black, hind tibae whitish, with 

 the apex and a ring before the base black, and terebra somewhat 

 shorter than the body (as long as the body without the head, 

 according to Marshall). 



Four males in Marshall's Collection in the British Museum 

 are the only examples I have seen and these I have not examined 

 carefully. jMr. Waterston tells me that a female (not a Marshall 

 specimen) which accompanies them is wrongly placed, being, 

 apparently a Microdus. 



Earinus tranversus, pp. nov. 



Black, shining ; mouth piceous, mandibles usually lighter, palpi 

 pale ; antennae dark, with extreme apex of second joint and base of 

 third rufous ; orbits immaculate ; legs testaceous, hind coxjb and 

 femora rufous ; hind tibige whitish, apically black, and with a faint 

 trace of a dark band before the base ; hind tarsi black. Wings 

 hyaline, first cubital cell very distinctly separated from the first 

 discoidal, second cubital cell subquadrate, usually externally in- 

 complete ; squamulge testaceous, stigma and nervures fuscous. 

 Antennae 37-jointed in both sexes. Mesothorax smooth, feebly
