on in the night, besides requesting a number o£ friends, to whom I 

 sent larvae, to watch carefully, with a view to confirm it ; but I believe 

 none of us were able to do so. Possibly, Mr. Barrett was not entirely 

 mistaken on the point, but if not, I am quite satisfied that the occur- 

 rence he noted was very exceptional if not purely accidental. 



The cocoon is spun among the debris on the ground, or very often among the 

 leaves or stalks of the food plant ; it is oval, toughly formed of brown silk, and 

 rather small for the size of the larva. 



The moths emerged in large numbers last June, and, so far as I 

 could see, the changed food, and modified colouring in the larvae, had 

 not a-ffected the imagines in any respect. From them I have now 

 pupse again, and so hope to still further experiment with the species 

 during this year.

ON A NEW ONTHOPHILUS FROM MEXICO. 

 BY GEORGE LEWIS, F.L.S. 



Onthophilus Julii, n. sp. 



Breviter ovatus, suhopacus ; thorace ohscure cpneo ; elytris 6-carinatis, 

 carinis multo inter r wptis ; prosterno metasternoque grosse punctatis. 



Long., 2 mm. 



Short oval, little opaque, black, w^ith a brassy tinge on the thorax ; the forehead, 

 coarsely rugose, pitted vrith irregularly shaped punctures, median carina strong, an- 

 terior edges raised, meeting in a point behind the epistoma, on each side near the 

 eye is a small emargination on the frontal edge ; the thorax faintly brassy, lateral 

 margin raised, central area 6-carinate, outer carina short and a little oblique, the 

 next nearly as long again, much shortened behind the head, less so at the base, two 

 median much longer, shortened only at the base, and posteriorly widening out a 

 little from each other, surface closely covered on the sides with large round punctures, 

 interstices of the punctures very slightly raised, the basal edge behind the carinse is 

 transversely punctured, punctures circular, but much smaller than those of the lateral 

 margins, the interspaces between the four median carinse have somewhat oblong punc- 

 tures, and the interstices of the punctures are arranged longitudinally in a strigose 

 form ; the elytra having the carinse much broken, giving the dorsum when viewed 

 sideways an appearance of having a number of small tubercles, first carina longest, 

 portion at the base twice broken, apical part shortest, second indistinct, but appa- 

 rently twice interrupted, third in three distinct portions, fourth very widely broken 

 in the middle, fifth much less distinct but more complete, sixth feebly raised, broken 

 at intervals, sutural elevation shortened before the scutellum, interstices of all the 

 carinse trilinear, with transvei'se impressions at short distances ; the propygidium and 

 pygidium are roughly punctate, the first with a median carina ; the prosternum 

 wholly covered with large circular punctures, base sinuous ; mesosternum narrow,
