COLYDIIDAE. 527 



In Bitoma the body is elongate, parallel, and glabrous. Tbe sides are 

 not explanate, the thorax is without lobes, the tibiae are slender and finely 

 bispinose at the extremity, the epipleurae are quite linear alongside the 

 abdomen, and the antennal cavities are not prolonged behind the eyes. 

 In Ulonotus the terminal joint of the maxillary palpi is securiform, the 

 antennal cavities are obliquely prolonged, and the antennal club is tri- 

 articulate. Allobitoma must be located between these, near Notoulus, which 

 also differs in appearance and structure. 



4049. Allobitoma halli sp. nov. 



Subopaque, obscure ferruginous, irregularly clothed with minute brassy 

 setae ; moderately elongate, convex along the middle, with granular sculp- 

 ture, the elytral apices dehiscent, thick and prolonged. 



Head subquadrate. Thorax, including the explanate sides, a third 

 broader than long, deeply sinuate behind the eyes ; disc nearly plane along 

 the middle, with a pair of prominent, almost horizontal apical elevations 

 which extend a little backwards, and with a small, quite transverse depres- 

 sion close to the middle of the base ; each side has a deep median notch, 

 the frontal portion is trilobed, the hind part is about as long as the other 

 and, in front, extends as far outwards, the side, however, is only a little 

 sinuate towards the obtusely prominent hind angle. Elytra of the same 

 width as thorax at the base, rather broader behind the curvedly narrowed 

 shoulders, gradually narrowed posteriorly, with subserrate margins, they 

 are 2|- times the length of the thorax ; each elytron has an elongate basal 

 ridge, and another farther back but nearer the side, the top of the posterior 

 declivity is strongly nodose ; their granular sculpture is seriate, but near 

 the sides minute tubercles are discernible. 



Legs very thick, bearing numerous grey setae ; basal three joints of 

 tarsi about equal and, together, hardly as long as the fourth. 



In its natural condition it is encrusted with tawny-grey sappy matter 

 which conceals the sculpture, even the thoracic lobes are only vaguely 

 defined. 



The only species at all similar in facies, 325, TarphiomimKs acuminatus, 

 will no doubt be placed in another genus apart from Tarphiomimiis. 



Length, 4|-5 mm. ; breadth, l|-2 mm. 



Glenhope ; 20th December, 1914. It is with pleasure that I attach 

 the name of its discoverer, Mr. T. Hall, to this remarkable little creature, 

 now represented by two individuals.

4050. Glenentela costata sp. nov. 



Oblong, broad, opaque ; pale rufo-fuscous, legs and antennae light red 

 and finely setose, tarsi testaceous ; in its natural condition covered with 

 greyish sappy matter which is difficult to scrape off. 



Head half the width of thorax, irregularly and finely granulate, slightly 

 impressed along each side of the middle ; labrum rufescent, prominent, 

 rather narrow and smooth ; mandibles minutely bifid at the extremity. 

 Thorax quite a third broader than long, its sides nearly straight behind, 

 curvedly narrowed before the middle ; base widely sinuate towards its 

 rectangular angles, apex subtruncate in the middle but with its thick 

 prominent angles extending to the small eyes ; disc transversely convex, 

 with a pair of costae, these are elevated in front, much less so, and composed
