A New Lac -Insect. 



By T. D. A. COCKERELL. 



The lac-insects ( Tachardia) are for the most part members 

 of the tropical fauna, and only a few species occur within the 

 boundaries of the United States. In New Mexico T. cornuta 

 Ckll. has long remained unique, and I did not expect to see a 

 second species from that region. However, one has come to 

 hand, and from a locality in which I have collected many 

 times, without finding it. It must be extremely local ; the 

 explanation of this fact is sufficiently evident when on boiling 

 up the material received, I find it severely attacked both by 

 a fungus and a chalcidid. 



Tachardia glomerella n. sp. 



Crowded on the sterns of Gutierrexia gloim~rclla Greene the indivi- 

 duals coalescing in large numbers, but not (in the material received) en- 

 tirely surrounding the stems ; color very dark, with translucent shining 

 orange-red rounded bosses, suggestive of guava jelly ; scales smooth and 

 roundec, without (even when young) any distinct projection such as is 

 seen in T. cornuia ; female when boiled and mounted colorless, about 3 

 mm. long ; the crimson pigment produced on boiling very abundant, 

 making the liquid extremely dark ; caudal process yellowish-brown, only 

 moderately chitinized, very broad basally, emitting no hairs from its apex ; 

 dorsal excretory processes cylindrically slightly broadened to the base, 

 colorless. 



Larva with antennae 6-jointed, joints 3 and 6 long (6 longest), the others 

 short, 4 and 5 with a stout spine subapically, 6 with a similar but larger 

 spine at about the beginning of its last third ; apex of 5 with two ex- 

 tremely long hairs, nearly twice as long as the sixth joint. 



Found on the mesa near Little Mountain, Mesilla Valley, 

 Ne\v Mexico, Oct. 6, 1904, by Dr. David Griffiths. Commu- 

 nicated by Professor E. O. Wooton. 



Larger and darker than T. cornuta, and without the protu- 

 berance. Much darker and otherwise different from T. fi/l- 

 gcns Ckll. ; without the stripes and lateral foot-like processes 

 of T. fulvaradiata Ckll. The Guticrrc.ia is very abundant in 



the Mesilla Valley.

PUI.YIXAIUA KICUS Hempel. Thiscoccid was recorded from the \\Vst 

 Indies by Maxwell-Lefroy, who gave measurements of the antenna- and 

 legs. An examination of the data presented shows that the species was 

 not P. ficns at all, but /'. inf>a)iia- Ckll. The true /'. Jicus is known 

 only from Brazil. T. D. A. COCKKKKU..
