NEW SPECIES OF THE FAMILY IPID^ (COLEOPTERA). 



BY J. M. SWAINE, 



Assistant Entomologist for Forest Insects, Division of Entomology, Ottawa.* 



An undescribed species of the genus Trypophlœus was recently- 

 received from Weymouth, N.S. Mr. G. E. Sanders, who collected 

 the material, has found the species in the vicinity of Weymouth 

 only, in dying stems and twûgs of Alnus. 



This species is closely related to T.alni Lind., of Russia, which 

 breeds in the bark of Alnus mcana but is distinguished by its 

 shorter wing covers, coarsely punctured but not granulate hinder 

 half of the pronotum, and unimpressed elytral striae. 



Trypophloeus nitidus, n. sp. — Black (when matured) ; lengthy 

 2 mm.; width, ^ mm.; clothed with short, inconspicuous, grey 

 hairs of two lengths; pronotum small, from above subtriangular; 

 elytra with rows of punctures, interspaces finely, confusedly punc- 

 tured; the whole body shining. 



The head is subglobular, punctured rather variably with 

 coarse, very shallow punctures and faintly aciculate behind the 

 eyes; the whole head often reticulate from very minute, dense^ 

 shallow punctures; the front more coarsely, closely, and rather 

 roughly punctured. A median, longitudinal impression extends 

 down the front and ends in a V-shaped impression at the base of 

 the epistoma. The front is rather sparsely clothed with short, 

 gray hairs. The epistoma, which bears a few long, yellowish hairs, 

 is widely margined, shining and produced at the median line into 

 a broad lobe, the upper surface of which is distinctly concave. 

 The eyes are wide, coarsely granulated, slightly emarginate in 

 front. The antennal fossa is small, rounded, and lies in the very- 

 short space between the eye and the base of the mandible. The 

 antennal scape is strongly curved and clavate; the first segment of 

 the funicle is large and pedunculate, the remaining four seg- 

 ments saucer-shaped and rapidly widened. The club is elong- 

 ate, narrowed distally, and truncate, with three transverse sutures,, 

 of which the third is indistinct. The sutures are more densely 

 hairy on the outer side, on the inner side the first suture is some- 

 times incomplete. The outer surface of the truncate tip bears a 

 large, stout seta at each end.
