than any of its hitherto recorded localities. The most northern 

 locality given for it by Dr. J. Sahlberg, I.e., is Lyngen, Finmark 

 (69° 34' N.). 



T. stupidula may always be distinguished from T. subfuscula, the 

 most nearly allied British species, by its greenish-yellow ground-colour, 

 even when the dark markings on the elytra are obsolete or entirely 

 wanting. 



Deltocephalus propinquus. 



Deltocephalus propinquus, Fieb., Verb. z.-b. Ges., XIX, 204, 5, 



tab. V, fig, 5. 



Allied to D. punctum, Flor, in the pointed form of the head. 

 Brownish-yellow ; the nerves bounding the base and apex of the first 

 sub-apical area thickened and milk-white. Very variable in the dark 

 markings of the elytra, sometimes these are entirely absent, while in 

 the darkest form all the areas are narrowly margined with fuscous, 

 and many intermediate forms occur. In what appears to be the 

 commonest form the upper margin of the first sub-apical and the hind 

 margins of the apical areas are narrowly bordered wdth dark fuscous, 

 and the hind margin of the fourth sub-apical area is also bordered with 

 the same colour in such a manner as to nearly resemble the dark spot 

 observable on the elytra of D. punctum, Flor. 



(J . Genital Talve triangular, shining black ; plates (taken together) triangular, 

 broadly truncate at the apes, about two and a half times as long as the valve, entirely 

 covering the hypopygiuin, dark brown with pale yellowish margins. Lower margins 

 of the hypopygium (viewed from below) with a falcate, acute, corneous, dark brown 

 process placed near the middle and directed inwards and backwards. Inner processes 

 is/riffel of Fieber) deep shining black, about half as long as the plates, somewhat 

 curved, obtuse, and having at their base a straight tooth which is about two-thirds 

 as long as the process itself. 



? . Hind-margin of the last ventral abdominal segment with two small obtuse 

 triangular teeth which are about equidistant from the side-margin of the segment 

 and from each other. Entire segment brownish-yellow with an oblong black patch 

 on the hind-margin, including the teeth, and below each tooth there is almost 

 invariably a black dot, but this latter is evidently caused by the bases of some muscles 

 connected with the ovipositor shewing through the pale portion of the segment, since 

 it disappears when the segment is dissected out. Length, 2 lines. 



The locality indicated in Dr. Futon's "Catalogue" (1875) for 

 this apparently little-known species is Andalusia. It seems to be 

 tolerably common in Norfolk, and is probably overlooked elsewhere. 

 I have examined 42 examples (24 cj 18 ?).
