Male: Front excavated, excavation smooth at middle and anteriorly 

 with a small tubercle. Tubercles on the elytral declivity more prominent. 

 Female: Front not excavated, but with a narrow median carina not 

 reaching the vertex. Tubercles on the elytral declivity smaller. 



These sexual characters are nearly the same as in the European 

 F. thujoe. 



PhlcEOsinus serratus. 



Can this be the male oi dentatus^. The specific difl'erences given b\ 

 Dr. Leconte are about the same as those between' the two sexes of the 

 European Ph. Aubei. Both forms, that with alternately elevated elytral 

 interstices {serratus) and that with equal interstices [dcntaius) have tlie 

 same food plant (Juniper), were beaten by Mr. Ulke and myself from 

 the same trees, and have the same geographical distribution. Still, ab- 

 solute proof of their identity is wanting, but the question can be easily 

 settled by anyone who has the opportunity of finding colonies of the 

 beetle still in their larval galleries. Both forms are widely distributed, 

 occurring from Maine to P'lorida and from Dakota to Texas and Arizona, 

 and I can see no reason why Ph. Haagi^Achh., (Berl. Ent. Zeit. 1868) 

 should not be synonymous with diviahts. and Ph. gratiiger Chap. (.**'yn. 

 d. Scol., p. 247) with serraiu.<; . 



Dendroctonus. 

 I have laielv examined, in company with Mr. Ulke, a large seric.'< 

 of specimens in our collections, and we found that our species could be 

 sharply separated and all difiiculties in their determination removed if 

 D. rufipennis, punctatus and simplex were considered to form a single 

 species, variable in size and sculpture of head and thorax. The variation 

 in size between these three forms is not greater than that exhibited in D. 

 terebrans and the same sculptural differences may also be observed in the 

 latter species. However, nothing definite can be .said before the life- 

 history of the different forms has been studieil. 



Crypturgus atomus 

 seems to be identical with the l'.uroj)ean C. pitsd/ns {]\\\\\. (.see Eichhoff, 

 Europ. Borkenk., p. 166). 



Hylurgops pinifex 

 is synonymous with the European Hylastes g/abratus /elt. 



We regret to record the death of Mr. Fredk. W. Klages of I^ittsbugh, Pa., who 

 died of pneumonia on the 27th day of March 1886 in the 27th year of his age. Mr. 

 Klages was an enhusiastic collector, and though a mechanic, with little time to spare, 

 yet gathered a considerable collection. He collected in Kenttickv, Florida and la 

 niaica as well as in the vicinity of Pittsburgh.
