FIVE NEW COCCIDA'- FROM MEXICO. 45 



ambulacra, genital sagment, testaceous ; rest of ventral surface blackish 

 grey. Autennte : first segment twice as long as head, oue-third 

 longer than second, which is one-half longer than third, fourth one- 

 fourth longer than third. Posterior lobe of pronotum superficially 

 cariuate longitudinally, subtectiform, rounded posteriorly. Anterior 

 femora scarcely incrassate ; intermediate femora three-sevenths longer 

 than tibiffi, which are somewhat more than five times as long as the 

 subcylindrical tarsi. Second tarsal segment about two and a half 

 times as long as first, and about twice as long as claw. Posterior legs 

 of similar proportions. Elytra reaching beyond apex of abdomen. 



<y . Abdomen beneath : fourth to seventh segments laterally some- 

 what compressed, medio-longitudinally sulcate. Apical margin of 

 seventh segment roundly but not profoundly emarginate ; eighth a little 

 longer medianly than seventh ; ninth about equal to eighth. Long, 

 excl. elytr. 5-8 mill. ; lat. max. 1*7 mill.

FIVE NEW COCCID^ FROM MEXICO. 

 By T. D. a. Cockerell. 



Mytilaspis mimosarum, n. sp. 



? . Scale 2 to 3 mm. long, brownish white, narrow, convex, 

 usually curved ; exuviae orange-brown. 3" scale as usual. Compared 

 with the next species (M. towmendiana) the scales are larger, and not 

 so pure white. 



? . Adult. Colour (after boiling in KHO) greenish or pale orange, 

 the anterior end sometimes slightly pinkish. Five groups of circum- 

 genital glands ; median of 9, anterior laterals 16 to 18, posterior 

 laterals 9 to 10. Only one pair of distinct lobes, these large and 

 brownish, rounded, slightly crenulated or entire, separated by an 

 interval in which are two pointed squames. A pair of pyriform glands 

 at the base of each median lobe, but quite at the lateral margins, though 

 the outer one is curved inwards ; second lobe represented by two colour- 

 less minute lobules, the inner one the larger ; after this come a spine 

 and a pair of large spine-like squames ; then two broad and very low 

 eminences representing the third lobe, the second usually minutely 

 crenulate ; then a spine and two very large spine-like squames ; then 

 after a considerable interval two or three more spine-like squames, and 

 three such on the lateral margins of each of the next three segments. 

 None of the segments have their lateral margins noticeably produced. 

 Submarginal transverse glands as usual ; dorsal glands as usual, not 

 especially numerous. Anal orifice about opposite the median group of 

 circumgenital glands, and 138 /x distant from tips of median lobes. Skin 

 minutely striated throughout. Length of the longest squames, 24 /*. 



? . Second stage. Colour (after boiling) pale yellowish brown ; 

 one pair of large low lobes ; large squames.
