130 THE ENTOMOLOGIST. 



three insects carefully and find distinct traces of a medial 

 metathoracic carina in the male. Unfortunately, the insects 

 are not in very good preservation and are carelessly mounted 

 as all Cameron's insects appear to be. Harwood has also 

 another male, labelled " M. tibialis," by Marshall, which is 

 certainly the same. 



Scoticus, Marsh.* 



This species is distinguished by its unusually long antennae 

 and short abdomen, the third segment being sub-rugulose. 

 I have seen the type, also in Harwood's collection, which is still 

 in good preservation (the antennae were broken at the time 

 it was described by Marshall) and bears the original label. No 

 other example has yet been recorded. 



Genus 6. — Hygroplitis, Thorns. 



Founded for the reception of two species, Microgaster 

 russatus, Hal., and M. riigulosus,, Nees, to which we must now 

 add M. abdominalis, Nees, a species with which Thomson was 

 not acquainted. The original description {opus xlvii, p. 2238) 

 is as follows : 



"Alffi areola completa, Tibiae posticae calcaribus longis. Sternauli 

 sat distinct!. Abdomen segmento 2:0.3:0 rugoso fere duplo 

 longiore. Unguis et pulvillus magni." 



Abdominalis, Nees.f 



After riissatiia, the finest species of the family ; is easily 

 recognised by the bright orange colour of the inner half of the 

 stigma. This is, no doubt, the insect described by "VVesmael 

 as M. deprimator, Ynnz.l Hitherto it has been noticed on the 

 Continent only, but I am adding it to the British list on 

 the strength of a fine male capture by Harwood in High 

 Woods, Colchester, in 1906. A scarce insect, very few captures 

 having been recorded ; the female is mentioned by Reinhard 

 only who says it resembles the male and has a very short 

 terebra . 



liussatiis, Hal.§ 



This large and striking species has the first three abdominal 

 segments entirely rufous and the stigma bicolorus. A scarce 

 insect which has not yet been bred in this country ; on the 

 Continent Brischke records it {vom OrtJiotelia spargaiiella. The 

 only specimen I have seen, with the exception of those in the 

 National Collection mentioned by Marshall, is a fine male taken 

 by Harwood, near Colchester, on August 2nd, 1914.
