Sicondury sexual character of Glbhiavi svutius F. — Having had a number 

 ofliving- Gibhium handed to me for my collection b}' Mr. Potter, I carehdly 

 exannned theiu in the hope of discovering a character whereby they could be 

 readily sexcd without the necessity of dissecting out the genitalia, and to my 

 satisfaction found that the mah' has a long upright tubercle on the uieta- 

 sternum between the posterior coxae ; in the female this is only very slightly 

 indicated, so that they can be quite easily separated by examining the meta- 

 steruura. This character was verilied in half-a-dozen different specimens by 

 dissecting out the genitalia. — II. BitiTTKN, 22 Birch drove, Jjevenshulnie,

iJiubroticu s»rur Ja-c. in Glainorijanshire. — L took an exarajde of this North 

 American insect crawling on some saud-hdls near the sea at (iower in April 

 1918. This Galerucid beetle is known in the U.y.A. as a pest on maize. 

 I iini much indebted to Dr. Gahau fur ideutifying the s])ecies. — PI. E. Daa'jd,

 mills at Droylsden, near Ma^ichester. — 



Ptinns tectus Boield. — One specimen taken in August 1917, in mill. 



Niptus hololcHcns Fall. — Found in a hottse at" Droylsden in abundance 

 during 1917 and 1918. Specimens were frequently seen in the pantry after 

 nightfall, as tjiey came i3ut foraging, the insect retiring as the light ap- 

 proached into little chinKs under the shelves and nail-holes. Two examples 

 taken in mill. 



Trit/oHoyenlns (jlobulum Sol. — Eleven specimens, four of which were found 

 dead in the tiro-buckets, the remainder I took by making little traps of sugar 

 wdiich proved an attraction for them. The dates of capture are as follows : 

 one specimen, June 1917, one on July 15th, 1918, the remainder in Januarv 

 and February, 1919. 



Gibhium scotias F. — On iMarch 9th, 1918, on ripping off a piece of iiuif 

 from the wall, an insect was discovered which looked like a small spider ; 

 this, however, on unfolding its legs, showed itself to be a beetle. On May 20th, 

 1918, a second example was loimd, creeping on the wall. On January 19th, 1919, 

 I found one dead in a tire-buckel, and on January 21st two more, this convincing- 

 me that they occurred some where else in the mill, and that those I had already 

 found were only str;iy ones. I therefore sought and obtained permission to 

 visit the mill when the machinery was stopped. On February 2ud, 1919, I 

 went in and succeeded in tinding the colony. It is evidently a warmth-loving
