Mr. T. D. A. Cockerell on some Mexican Coccide. 47 
XIII.—WNotes on some Mexican Coccide. 
By T. D. A. CocKERELL. 
HAvinG recently had occasion to travel through Mexico, I was 
naturally anxious to collect as many Coccide as I could, 
having paid much attention to that group of late. ‘The Coccide 
of Mexico, so far as I can find them recorded, number fourteen 
species, and to these twelve more can now be added, making 
twenty-six altogether. 
Arriving at Vera Cruz on May 7, the first Coccid I saw 
was Aspidiotus jficus on an orange on the table at the hotel. 
In the hotel were several plants growing in large pots, and an 
‘examination of these yielded Aspidiotus jficus, Lecanium 
hesperidum, L. terminalia, and Planchonia pustulans. 'To- 
wards evening I had an opportunity to go out into the plaza, 
and almost immediately came across a beautiful bright yellow 
Pulvinaria, a new species, on Croton. Further search led to 
the discovery of Orthezia insignis and Aspidiotus articulatus. 
The next day we took the train to the City of Mexico. 
While the train stopped at Soledad, in the State of Vera 
Cruz, Iran out and picked a few leaves, on which I found 
Aspidiotus articulatus and an interesting new species of the 
same genus. It was quite evening when we arrived at 
Mexico City ; but, strolling out, a few small specimens of a 
Dactylopius were found on a tree in one of the streets. ‘The 
next day the same species occurred on two or three trees in 
front of the cathedral, and I was so fortunate as to get adults, 
both male and female, which on examination showed the 
species to be undescribed. At the same place Lecanium olee 
was common on many trees, and in the gardens of the public 
library I found Lecanium hesperidum. 
The two following days were spent in travelling, and, 
although a good look-out was kept at the stations, no Coccidee 
were found, At about 2 A.M. on May 12 we were suddenly 
awakened by a sharp shock, and the train came to a stand- 
still. It proved that the engine and freight cars in front had 
left the rails, owing to a ‘ wash-out,” and consequently we 
had to spend many hours in the middle of nowhere, six miles 
north of Montezuma R. R. Station, in the State of Chihuahua. 
This was a desert spot, unfavourable for collecting; but a 
search revealed an undescribed Ceroplastes on Artemisia. 
Later, while the line was being mended, they took us back to 
Montezuma, and here I found another Ceroplastes, also new. 
Thus, out of twelve Coccidz found during the journey
