the Cylindrotominpe. before me, and working with Schiuer, I quickly 

 ran it down to Triogma trisulcata, Schum. This species is characterised 

 by the antennal joints being hardly longer than wide, by the thorax 

 having three longitudinal grooves, the outer two, as well as the sides 

 of the dorsum, being punctured; and by the peculiar venation: the 

 3rd long vein arising from the 2nd before the discal cell, and after 

 forming for a short distance part of the upper boundary thereof, 

 branching off and going to the apex of the wing. Zetterstedt (Dipt. 



Scand., X, p. 3879) says : " abdomine testaceo, vitta dorsali 



fusca." Schiner has no mention of a dorsal stripe, and it does not 

 show in the present specimen. 



It appears that the specimen under discussion was received by 

 Mr. Bloomfield, many years ago, from Mr. R. C. Bradley, of Sutton 

 Coldfield, as Phalacrocera replicata, L., a species to which it bears a 

 superficial resemblance. Mr. Bradley recoi'ded P. replicata in Ent. 

 Mo. Mag., 1894, p. 17. I do not suggest that this record was 

 erroneous. It is more probable that the Triogma, being subsequently 

 taken in the same locality, was overlooked. 



The specimen is a (J , and bears a label in Mr. Bradley's hand- 

 writing, " Sutton, 16, 6, 99," so that this interesting (generic as well 

 as specific) addition to our List was captured nearly thirteen years 

 ago ! 



According to Osten Sacken (" Studies in Tipulidee ") there is but 

 one European species of Triogma. It appears to be rare, and is 

 recorded by Zetterstedt from Sweden and Denmark, and by Schiner 

 from Germany and Austria.

A NEW FOEM OF BED-BUG: CACODMUS IGN0TU8, sv. nov. 

 BT THE HON. N. CHARLES ROTHSCHILD, M.A., P.E.S. 



Closely allied to Cacodm^is villosus, Stal. 



Head, thorax, elytra, abdomen, and legs densely covered with rather long 

 hairs inserted in pits ; coloiu- madder brown. Head without labrum about half 

 the length of the pronotum and very deeply placed, the pronotum reaching well 

 to the eye. Relative lengths of antennse as follows .- — 18, 54, 37, 39. 



Pronotum at the apex truncate, far wider than it is long. The sides are 

 rounded, but are less so than in C. villosus, Stal. Anterior angles of the pronotum 

 slightly produced and reaching to the centre of the eye. Posterior edge of
