Black and somewhat shining. Head transverse, broader than the thorax, 

 narrowed behind eyes ; face parallel-sided and very finely punctate ; 

 mouth and apex of clypeus rufescent. Antennae of ^ almost as long as, 

 of 9 shorter than, the body. Thorax with the mesonotum very finely 

 punctate; mesopleurae somewhat shining and finely punctate; metanotum 

 finely rugose, with areola distinct. Scutellum immaculate. Abdomen 

 with the three basal segments very finely punctate, red with in 9 3- cen- 

 tral black fascia, J with the first entirely and second basally black; the 

 remainder smooth and shining ; basal segment of 9 twice, of J more 

 than twice, longer than broad ; second quadrate, or in ^ longer than 

 broad ; third of J quadrate, of 9 subtransverse ; terebra as long as the 

 abdomen. Legs red with the coxae and base of the hind trochanters of 

 c? black. Wings and stigma pale brown ; tegulae pale piceous ; areolet 

 pentagonal with the outer nervaire obsolete ; radial nervure externally 

 slightly curved ; nervellus intercepting a little below the centre. Length, 

 3 mm. 



Bridgman says this species is related to /.. ///nan's but is much smaller, 

 the second and third segments shorter and the nervellus intercepting 

 nearer the centre. I have seen nothing quite so small as this species, and 

 should suggest from its general debility that it is a starred form of one of 

 the S('g//ie/i/a/or-group of species, possibly Z. fi/'gndtus, with which it 

 agrees in several important particulars and which has been bred from the 

 same host. 



A single example of both sexes was bred in the neighbourhood of 

 Littlehampton by W. H. B. Fletcher from Psyche intcnncdiella, as recorded 

 by Bridgman ; no one here or abroad has since met with it. 



10. nitida, Bridg. 



Lissonota niticia, Bridg. Trans. Ent. Soc. 1886. p. 371 ; Schm. Zool. Jahr. 1900,

Somewhat shining and black. Head transverse and obliquely narrowed 

 behind the eyes ; face and frons finely punctate with the interstices reticu- 

 late, the latter smooth between the scrobes and finely rugose centrally 

 above them ; clypeus apically rounded and pale fiavidous. Antennae fili- 

 fonu and not apically attenuate, almost as long as the body. Thorax 

 immaculate ; mesonotum finely punctate, with the interstices almost obso- 

 letely reticulate, and notauli wanting ; mesopleurae similarly sculptured, 

 with the reticulations more distinct ; metathorax somewhat finely and 

 roughly punctate, subimpressed centrally. Scutellum black. Abdomen
