Genera of the Cossonida. 591 



diate forms ; but in its elytra being more produced (or less 

 obtusely-rounded) behind, in its shoulders being rather 

 suddenly and acutely porrected, and in the front tibiae of 

 its type being armed at their inner angle with a compressed 

 bifid spur, there is a singularity about it which is essen- 

 tially its own. The two species of Tomolips which are 

 now before me were taken in Mexico, and are from the 

 collection of Mr. Fry. 



118. DENDROCTONOMORPHUS (nov. gen.'). It is for a 

 Hylastes-, or Dendroctonus-like Cossonid from Ceylon, 

 which (together with an allied species from Malabar, 

 and a rather less typical one from Mexico) has been com- 

 municated by Mr. Fry, that I have been compelled to 

 establish the present genus. In its structural peculiarities 

 it is somewhat intermediate between Brachytemnus and 

 Stenoscelis, agreeing with the former in its conspicuous 

 (though less largely developed) scutellum, comparatively 

 elongate, almost unconstricted prothorax, the general 

 character of its sculpture (which however is not quite so 

 coarse), and in its perfectly simple third tarsal joint; but 

 with the latter in its asperated elytra, greatly lengthened 

 feet, more widely separated eyes, and less glabrous an- 

 tennse. In its thickened head, short, triangular rostrum, 

 sunken eyes, and cylindrical body, it is in accordance with 

 the whole of these sub-Hylastideous forms. 



119. BRACHYTEMNUS (nov. gen.). It is in order to 

 receive the European Rhyncolus porcatus, Miill., and my 

 nearly-allied R.pinipotens from the Canarian archipelago,* 

 that I have proposed the present genus ; and it seems mar- 

 vellous to me now how those curious insects could ever 

 have been included amongst the Rhyncoli from which 

 they appear to differ in nearly every detail of their 



* My B. pinipotens ( = crassirostris, olim), which I captured in an old 

 fir-tree in the island of Grand Canary, is most closely allied to the B. por- 

 catus, Miill., of Southern Europe. Its rostrum and prothorax however (the 

 former of which is free from an anterior channel, whilst the latter is less 

 sinuated on either side behind the middle) are just appreciably less coarsely 

 and more sparingly punctured ; its elytra (which have the shoulders less 

 porrect) are a trifle more parallel, there being apparently no tendency to 

 be even obsoletely widened posteriorly, and have their apical region less 

 obtusely- desilient (or suddenly bent-down wards) ; and the club of its an- 

 tennae is rather more truncated in front. The underside also is somewhat 

 less grossly punctured, and the first abdominal segment, which is convexer, 

 is likewise a little more remotely so.
