LicJitensia colimensis, sp. n. 



? .— Ovisac white. Skin with numerous large colourless 

 oval pits, 15-21 /z long; spiracles large, the outer ring about 

 75 /A diameter ; margin with numerous sharp spines, as in 

 the other American members of the genus ; anal plates 

 ordinary, about 165 /jl long ; legs and antennse light brown ; 

 claw-digitules with large knobs, extending considerably 

 beyond claw; tarsal digitules as in L. crescentice] bin I 

 tarsus with a constriction ; antennas 8-jointed. Measurements 

 of legs and antennse in /u. : — Anterior leg — femur + trochanter 

 195, tibia 135, tarsus 63; hind leg — femur + trochanter 213, 

 libia 135, tarsus 75-81. Antennal joints : (1) 30, (2) 3G-45, 

 (3) 66-72, (4) 37-45, (5) 36-42, (6) 33-35, (7) 30, (8) 

 39-45. 



Hob. Colima, July 12 ; on Celtis (?). 



The antennje are as in L. lycii, except that joint 2 is 

 longer ; the tibia and tarsus are too small for L. crescenticB or 

 mimosce, but agree pretty well with hjcii. The constrictiou 

 of the anterior tarsus is a little before the middle in lycii; in 

 colimensis a similar constriction exists, but a little beyond 

 the middle. 



Lichtensia zapotlana, sp. n. 



? . — Ovisac long, pure white, narrow, firm, not adhering 

 to objects ; length 6, breadth 2 millim. $ covered with an 

 easily deciduous glassy secretion ; the insect is very dark 

 brown and very hard to clear, remaining dark after prolonged 

 boiling in KHO. Anal plates ordinary; marginal spines 

 sharp, about 30 /j> long, and as far apart as the length of one ; 

 anterior leg with femur + trochanter 330, tibia 204, tarsus 

 100 fi; antennee 8-jointed, (1) 45, (2) 33-35, (3) 111-114, 

 (4) 69-81, (5) 60-66, (6) 39-40, (7) 30-32, (8) 45-51. 



(^ . — Scale glassy, roughish, with a subreticulate appear- 

 ance, dorsal area (between the longitudinal lines) about equal 

 to either lateral area. ^ reddish, marked with black ; costa 

 with a greyish-red stripe. 



IJab. Zapotlan, July 7, on a leguminous shrub. 



Seems near to L. argentata, Hempel. Pulvinaria pnrvnJd^ 

 Ckll., is also allied, and should stand as Lichtensia p irviila : 

 it is a smaller insect than zapotlana^ but has even larger legs. 

 It appears that in tropical Mexico (and possibly in tiie whole 

 Neotropical region) Lichtensia takes the place of L^ulvinaria^ 

 the species of the latter genus found there being introductions 

 from elsewhere. There are genuine species of Pulvinaria dt 

 present found only in the West Indies and Braz.il, but it is
